                                  THE COMPANY
 
     The Company designs, develops and markets proprietary radio frequency
integrated circuits ("RFICs") for wireless communications applications such as
cellular and PCS, cordless telephony, wireless LANs, wireless local loop,
industrial radios, wireless security and remote meter reading. The Company
offers a broad array of products, including amplifiers, mixers and
modulators/demodulators, that represent a substantial majority of the RFICs
required in wireless subscriber equipment. The Company designs products using
three distinct process technologies: GaAs HBT, GaAs MESFET and silicon bipolar
transistor. The Company believes that for certain applications, GaAs HBT devices
offer advantages in terms of linearity, efficiency, reduced system complexity
and size.
 
     The wireless communications industry has grown rapidly over the past decade
as cellular, PCS, paging and other wireless communications services have become
widely available and increasingly affordable. As wireless usage has grown,
wireless service providers have continued to improve the quality and
functionality of their services and have sought to offer greater bandwidth for
increased capacity. Capacity and functionality have been addressed by the
allocation of less congested frequency bands and by the wireless industry's
movement from analog to digital signal modulation standards. These digital
standards place a premium on linear power amplification, which can translate
into higher quality signals.
 
     The wireless markets are characterized by a proliferation of analog and
digital signal modulation standards including AMPS, TACS, TDMA, CDMA and hybrid
standards. The equipment designed for each standard generally requires unique RF
and baseband integrated circuit solutions which must be designed to meet the
demands of subscriber equipment users for greater functionality, smaller and
lighter equipment, longer battery life and better security, all at reduced
costs. As a result, many OEMs have relied increasingly on third party, value-
added technology providers that have the component and systems level expertise
to design, and the production capacity to supply, these solutions. The Company
believes this trend has been particularly evident in the RF segment due to the
scarcity of RFIC engineers and the design complexity of RF technology.
 
   
     TRW Inc. ("TRW"), which is the Company's largest shareholder and will
beneficially own 31.1% of the Common Stock of the Company after the consummation
of this offering, is currently manufacturing all of the Company's GaAs HBT
products using TRW's proprietary technologies and has granted the Company a
license to use its GaAs HBT process to design products for commercial wireless
applications. Through its relationship with TRW, the Company has become a
leading commercial supplier of GaAs HBT RFICs based on sales. The Company's GaAs
HBT power amplifiers and small signal devices have been designed into advanced
subscriber equipment manufactured by leading OEMs such as QUALCOMM, Nokia,
Hyundai, Samsung, Motorola and LG. The Company also offers GaAs MESFET and
silicon components through a delivery strategy called Optimum Technology
Matching(R) to complement its GaAs HBT products. Optimum Technology Matching(R)
allows the Company to offer RFIC solutions, on a component by component basis,
that best fulfill each OEM's performance, cost and time-to-market requirements.
    
 
     The Company's strategy is to focus on wireless markets by offering a broad
range of standard and custom-designed RFICs in order to position itself as a
"one-stop" solution for its customers' RFIC needs. To meet demand for the
Company's GaAs HBT products, TRW is expanding its GaAs manufacturing facility
and the Company is constructing an approximately 50,000 square foot fabrication
facility. The Company believes that operating its own GaAs HBT wafer fabrication
facility will improve its ability to respond to customer demand for GaAs HBT
products and will provide it with greater opportunities to enhance product and
process quality and reliability.
 
     The Company was incorporated as a North Carolina corporation in 1991. The
Company's principal executive offices are located at 7625 Thorndike Road,
Greensboro, North Carolina, 27409-9421, and its telephone number is (910)
664-1233.

                                  RISK FACTORS
 
     This offering involves a high degree of risk. In addition to the other
information set forth in this Prospectus, the following risk factors should be
considered carefully in evaluating the Company and its business before
purchasing any of the shares of Common Stock offered hereby. This Prospectus
contains certain forward-looking statements that involve risks and
uncertainties, such as statements of the Company's plans, objectives,
expectations and intentions. The cautionary statements made in this Prospectus
should be read as being applicable to all related forward-looking statements
wherever they appear in this Prospectus. The Company's actual results could
differ materially from those discussed in this Prospectus. Factors that could
cause or contribute to such differences include those discussed below, as well
as those discussed elsewhere in this Prospectus.
 
VARIABILITY OF OPERATING RESULTS; DEPENDENCE ON A LIMITED NUMBER OF CUSTOMERS;
GAAS HBT CAPACITY CONSTRAINTS
 
     The Company has experienced and expects to continue to experience
significant variability of its operating results. Future variability of
operating results may be caused by a variety of factors, including, but not
limited to: the demand for wireless subscriber equipment; the rate at which the
Company's gallium arsenide heterojunction bipolar transistor ("GaAs HBT") and
other products are adopted by customers; the ability of the Company to commence
commercial production at its planned fabrication facility; the ability of the
Company eventually to manufacture and deliver products in a timely and
cost-effective manner at acceptable yields and in volumes sufficient to satisfy
customer demands; the timing of significant orders; the mix of products sold;
changes in pricing by the Company and its competitors, customers or suppliers;
the length of sales cycles for the Company's products; variations in
manufacturing, assembly and test yields; market acceptance of customers'
products; the pattern of end-user or customer purchasing cycles; the
introduction of new products, processes and technologies by the Company and its
competitors; and general industry and global economic conditions.
 
     A substantial portion of the Company's revenues is attributable to
custom-designed products that are designed and manufactured for specific
customers. Custom products are often manufactured on an exclusive basis for the
originating customer for a negotiated period of time. In late calendar 1995 and
early calendar 1996, the Company's operating results fluctuated substantially
due to high material scrap caused by low manufacturing, assembly and test yields
related to the Company's development of a Code Division Multiple Access ("CDMA")
chipset for QUALCOMM Incorporated ("QUALCOMM"). There can be no assurance that
the Company will not experience similar problems while developing future
products. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Overview."
 
   
     A relatively limited number of customers have historically accounted for a
significant portion of the Company's revenues, and the identity of those
customers has varied significantly from period to period. In fiscal 1997, sales
to QUALCOMM and Samsung Electronics Co., Ltd. ("Samsung") accounted for 32.1%
and 23.4%, respectively, of the Company's revenues, and sales to the Company's
five most significant customers in the aggregate accounted for 73.0% of
revenues. In fiscal 1996, sales to QUALCOMM and Cincinnati Microwave, Inc.
("Cincinnati Microwave") accounted for 31.3% and 11.9%, respectively, of the
Company's revenues, and sales to the Company's five most significant customers
in the aggregate accounted for 60.7% of revenues. The Company expects that sales
of its products to a limited number of customers will continue to account for a
high percentage of its revenues in future periods. The Company also expects that
some of its key customers in future periods may be different from its key
customers in prior periods, and there can be no assurance that the Company will
be able to replace revenues generated by former key customers in prior periods
with revenues generated from existing or new customers in future periods.
    
 
     Due primarily to the Company's inability to meet requested delivery times
and quantity requirements, QUALCOMM has determined to produce internally certain
components and to look to other sources for other components to replace all
products currently purchased from the Company. Accordingly, the Company expects
sales to QUALCOMM to cease in May 1997. Further, the Company believes that
certain prospective original equipment manufacturer ("OEM") customers have been
reluctant to use the Company's GaAs HBT
 
                                        5
<PAGE>   9
 
   
products in their devices due to the Company's capacity constraints with respect
to such products. Although TRW is in the process of expanding its manufacturing
capacity and the Company is constructing its own GaAs HBT wafer fabrication
facility, the Company remains and will remain subject to capacity constraints
with respect to GaAs HBT products. As a result, there can be no assurance that
other customers will not seek alternate sources for certain high volume
requirements. The Company is attempting to replace sales previously made to
QUALCOMM with sales to other customers. A failure to replace sales previously
made to QUALCOMM would have a material adverse effect on the Company's business,
financial condition and results of operations.
    
 
   
     The Company has significantly increased its expense levels to support its
recent growth and intends to continue to make significant investments in
research and development, capital equipment and customer service and support
capabilities worldwide, especially as it constructs and begins to operate its
own wafer fabrication facility. These investments will make it difficult for the
Company to reduce its operating expenses in a particular period if the Company's
revenue goals for that period are not met. There can be no assurance that the
Company will achieve a rate of growth or level of sales in any future period
commensurate with its increased level of operating expenses and the failure to
do so would have a material adverse effect on the Company's business, financial
condition and results of operations.
    
 
     Due to the foregoing factors, as well as other unanticipated factors, it is
likely that in some future quarter the Company's operating results will be below
the expectations of public market analysts or investors. In such event, the
price of the Company's Common Stock would be materially adversely affected. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
DEPENDENCE ON TRW
 
   
     The Company believes TRW is one of only two suppliers of commercial
quantities of GaAs HBT wafers. The Company's GaAs HBT products are fabricated
solely by TRW using TRW's proprietary technologies. For the year ended March 31,
1997, sales of GaAs HBT products constituted approximately 85% of the Company's
revenues. The Company has entered into a supply contract with TRW pursuant to
which TRW is required to deliver to the Company certain minimum quantities of
GaAs HBT wafers until December 31, 2000, which quantities decline significantly
from current levels beginning in 1999. The Company currently is purchasing from
TRW a number of wafers that approximates the minimum number of wafers required
to be delivered by TRW to the Company under the supply contract. However, the
Company believes that in future periods it may purchase from TRW a quantity of
wafers in excess of the minimum quantity of wafers required to be supplied by
TRW under such contract. Although TRW has to date allocated to the Company a
substantial portion of TRW's commercial GaAs HBT wafer production, the Company
nevertheless has experienced significant difficulty obtaining sufficient
production capacity to meet demand for certain of its GaAs HBT products.
Further, although the Company plans to begin fabricating its own GaAs HBT wafers
in commercial quantities in the second half of 1998 using technologies licensed
from TRW, the Company expects to remain dependent upon TRW to satisfy the
Company's GaAs HBT production requirements in the future. The fabrication of
GaAs HBT wafers involves highly complex and unique processes, and a failure by
TRW to manufacture and deliver wafers on a timely basis, to maintain acceptable
manufacturing yields, to continue to allocate to the Company a substantial
portion of TRW's commercial wafer production or to successfully defend against
any claim that its GaAs HBT process infringes on third parties' intellectual
property rights would have a material adverse effect on the Company's business,
financial condition and results of operations.
    
 
     TRW currently is in the process of expanding its fabrication facility to
increase its capacity to fabricate GaAs HBT wafers. Technological, personnel and
manufacturing changes and new equipment purchases associated with TRW's
expansion, among other factors, may prevent or delay an increase in the number
of GaAs HBT wafers manufactured for the Company by TRW. Accordingly, there can
be no assurance that TRW will be able successfully to expand its capacity in a
manner that achieves acceptable manufacturing yields, cost and quality. Further,
the expansion of TRW's fabrication facility is subject to a determination by TRW
to postpone, downsize or terminate such expansion plans. A decision by TRW to
postpone, downsize or terminate its expansion plans, a delay in such expansion
for any reason or a failure to achieve acceptable
 
                                        6
<PAGE>   10
 
manufacturing yields would have a material adverse effect on the Company's
business, financial condition and results of operations.
 
     Pursuant to a license agreement between TRW and the Company, TRW has
granted to the Company certain licenses to TRW's GaAs HBT and molecular beam
epitaxial ("MBE") processes used to produce certain GaAs HBT products for
commercial wireless communications applications that operate on signals having a
frequency of less than 10 GHz. The Company plans to construct a fabrication
facility and begin manufacturing its own GaAs HBT products in commercial
quantities in the second half of 1998 using processes covered by such licenses.
Such licenses are granted without representation or warranty as to validity or
noninfringement and may be terminated by TRW if the Company's facility is not
operational, based on certain specified parameters, by December 31, 1998.
Further, certain exclusive licenses for GaAs HBT processes that may be used to
produce products for wireless communications applications may be made entirely
non-exclusive by TRW if the Company fails to meet certain revenue goals. A
decision by TRW to terminate such license agreement or to make the rights
granted therein non-exclusive or a determination that its GaAs HBT processes
infringe a third party's intellectual property rights would have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Business -- Strategic Relationship with TRW" and "Certain
Transactions -- TRW."
 
CONSTRUCTION AND OPERATION OF FABRICATION FACILITY
 
     The Company currently is in the process of constructing an approximately
50,000 square foot wafer fabrication facility at which the Company intends to
fabricate four-inch GaAs HBT wafers using technologies licensed from TRW. See
"Business -- Facilities." The Company expects to be able to manufacture GaAs HBT
products at a cost that is less than the price paid by the Company to TRW for
such products; however, there is no assurance that the Company will be able to
do so. Further, to date, the Company has never fabricated any semiconductor
wafers of any kind. Replicating at the Company's planned wafer fabrication
facility the precise manufacturing processes used by TRW at its GaAs HBT
facility will be labor intensive, technically challenging, time consuming and
logistically complex. It will require significant investments of labor and
capital by both the Company and TRW. The transfer process is scheduled to occur
over a two-year period and the major steps will include facility design,
equipment and material specifications and sourcing, clean room certification,
equipment installation and the hiring and training of skilled production
personnel. Once the clean room is operational, the Company must transfer TRW's
manufacturing process and run test wafers until the manufacturing process is
adjusted to the point where commercial production is feasible. Before production
can commence, wafers must be qualified by individual customers on a
component-by-component basis, even for products previously qualified by TRW at
its facility. While many of the technology transfer steps must occur
concurrently, other steps must occur after the achievement of certain milestones
and thus the delay in one or more steps could materially delay the entire
technology transfer process. As a result, there can be no assurance that the
Company will be able to transfer TRW's GaAs HBT processes successfully or in a
timely manner or that the Company will be able successfully to produce GaAs HBT
wafers in a manner that achieves acceptable manufacturing yields or allows the
Company to offer its GaAs HBT products at competitive prices. The failure or any
delay by the Company to adapt successfully the technologies employed by TRW or
to fabricate GaAs HBT wafers at acceptable manufacturing yields, costs and
quality and in volumes sufficient to satisfy customer demands would have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
     Although TRW has agreed to provide the Company with technical assistance,
training and instruction to facilitate this technology transfer, the ability of
the Company to complete a successful technology transfer from TRW will be
subject to numerous risks. In particular, TRW fabricates three-inch MBE wafer
starting material and three-inch GaAs HBT wafers at its facility, while the
Company will fabricate four-inch wafers at its facility. Accordingly, in
addition to replicating TRW's complex proprietary manufacturing processes, the
Company must be able to adapt such processes from three-inch wafers to four-inch
wafers, which involves a number of technical hurdles including the development
of new back-side wafer thinning processes for the larger wafers. These processes
have not yet been developed and no assurance can be given that such development
will be successful.
 
                                        7
<PAGE>   11
 
     The Company currently believes its fabrication facility will be operating
at commercial levels in the second half of 1998. Until such time, the Company
will purchase all or substantially all of its GaAs HBT products from TRW, which
currently is allocating to the Company a substantial portion of TRW's
manufacturing capacity. The Company believes the risk of losing orders for GaAs
HBT products, particularly from large OEMs who may require significant volumes
of certain products for their wireless devices, will increase significantly
during the second half of 1998 until its fabrication facility has begun
operating at commercial levels. The construction of such facility is subject to
various risks, including inclement weather conditions, unforeseen hazards or
conditions that hinder, delay or increase the cost of development,
unavailability of building materials, unavailability of manufacturing equipment,
construction delays and other conditions beyond the control of the Company.
Accordingly, there can be no assurance that the Company will be able to complete
such construction by the time indicated above. A delay in the completion of such
fabrication facility would have a material adverse effect on the Company's
business, financial condition and results of operations. In this regard, TRW has
the right to terminate the licenses granted to the Company if such facility is
not operational by December 31, 1998. See "-- Dependence on TRW."
 
     The fabrication of GaAs wafers involves precise processes that are highly
complex and unique, that require advanced and costly equipment and that are
being modified continually in an effort to improve yields and product
performance. The Company expects that its customers will continue to establish
demanding specifications for quality, performance and reliability that must be
met by the Company's products. Defects in masks, minute impurities in materials
used, contamination of the manufacturing environment, equipment failure and
small imperfections in the fabrication process can cause a substantial
percentage of wafers to be rejected or numerous die on each wafer to be
nonfunctional. In addition, the more brittle nature of GaAs wafers can result in
higher processing losses relative to traditional silicon-based semiconductor
processes. Moreover, the operation of a wafer fabrication facility requires
significant fixed costs, consisting primarily of occupancy costs, investments in
manufacturing equipment, repair, maintenance and depreciation costs related to
such equipment and labor costs related to manufacturing and process engineering.
There can be no assurance that the Company will have revenue to offset such cost
increases.
 
ADOPTION OF GAAS HBT COMPONENTS
 
   
     Commercial applications of GaAs HBT technologies are relatively new, and
certain current and potential customers of the Company may be reluctant to
design wireless systems that incorporate GaAs HBT products because of perceived
risks relating to GaAs HBT technology generally. Such perceived risks include
product reliability, the unfamiliarity of designing systems with GaAs HBT
components as compared with silicon or gallium arsenide metal semiconductor
field effect transistor ("GaAs MESFET") components, novel design requirements,
unfamiliar manufacturing processes and uncertainties about the relative cost
effectiveness of GaAs HBT products compared to high performance silicon-based or
GaAs MESFET integrated circuits. Further, there currently are only two suppliers
of commercial quantities of GaAs HBT wafers. Certain customers may be reluctant
to rely on a small company such as RFMD as a sole supplier of large quantities
of critical GaAs HBT components. For the year ended March 31, 1997,
approximately 85% of the Company's revenues was attributable to the sale of GaAs
HBT products, and the Company may remain dependent upon GaAs HBT products to
generate a substantial portion of future revenues. There can be no assurance
that additional OEMs will design the Company's GaAs HBT products into their
respective systems, that the companies that have utilized the Company's GaAs HBT
products will continue to do so in the future or that GaAs HBT integrated
circuit technology will achieve widespread market acceptance. Failure of GaAs
HBT to become widely adopted would have a material adverse effect on the
Company's business, financial condition and results of operations.
    
 
MANAGEMENT OF GROWTH
 
   
     The Company currently is experiencing a period of significant growth that
has placed and will continue to place a significant strain on the Company's
resources. The Company has grown from 67 employees on March 31, 1996 to 131
employees on March 31, 1997. The Company's ability to manage its growth
effectively will require it to implement and improve operational and financial
systems and to expand, train and manage its
    
 
                                        8
<PAGE>   12
 
employee base. In particular, the Company's prospects depend upon its ability to
attract qualified persons with experience in RF engineering, integrated circuit
design, wireless systems and technical marketing and support. Competition for
such persons is intense, and the number of persons with such experience is
limited. The Company also will be required to manage multiple relationships with
various customers, business partners and other third parties, such as its
foundry and assembly partners. Moreover, the Company will incur significant
expenses associated with its rapid growth and may incur additional unexpected
costs relating to its anticipated expansion, particularly related to its current
plan to build its own wafer fabrication facility. The Company's systems,
procedures or controls may not be adequate to support the Company's operations
and Company management may not be able to achieve the rapid expansion necessary
to exploit potential market opportunities for the Company's products. The
Company's future operating results will also depend on its ability to expand its
sales and marketing and research and development organizations, and expand its
administrative support organization. If the Company is unable to attract
qualified persons or manage growth effectively, the Company's business,
financial condition and results of operations would be materially adversely
affected.
 
RELATIONSHIP WITH NOKIA
 
     The Company, TRW and Nokia Mobile Phones Ltd. ("Nokia") have agreed in
principle to cooperate to develop and supply Nokia with RFICs that are
manufactured using TRW's GaAs HBT processes. The arrangement contemplates that
the Company and Nokia will negotiate separate agreements to address the
development and supply of each product. Pursuant to the arrangement, the Company
has agreed to provide Nokia with access to certain RFIC technologies and to the
Company's GaAs HBT foundry if and when such facility becomes operational, and
Nokia has agreed to provide the Company with rights to bid for and supply
Nokia's requirements for certain RFICs. The arrangement can be terminated
without penalty by TRW, the Company or Nokia for any reason. The arrangement
does not obligate Nokia to purchase any products from the Company, and there can
be no assurance that Nokia will become or subsequently remain a significant
customer or that the Company's relationship with Nokia will continue. A
termination by Nokia or TRW of this relationship would have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Business -- Customers."
 
LIMITED OPERATING HISTORY AND OPERATING LOSSES
 
   
     The Company was incorporated in 1991 and was in the development stage prior
to the year ended March 31, 1995. The Company had net losses totalling
approximately $14.4 million from the period of inception to March 31, 1996. As
of March 31, 1997, the Company had an accumulated deficit of approximately $12.7
million. The Company expects to incur substantial additional costs to construct
a fabrication facility and expand its operations and to design and develop new
products. Although the Company was profitable for the year ended March 31, 1997,
there can be no assurance, due to the Company's history of annual and quarterly
operating losses, its planned substantial expansion of manufacturing capacity,
its dependence on third parties and the difficulty of predicting the demand for
its products, among other factors, that the Company will be able to sustain such
profitability. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."
    
 
DEPENDENCE ON THIRD PARTIES
 
     All of the Company's products currently are manufactured by independent
third parties, and the Company expects to continue to rely heavily on
independent third parties in the future. The Company purchases all of its GaAs
HBT products from TRW, which the Company believes is currently one of only two
suppliers of commercial quantities of GaAs HBT wafers. In addition, the Company
uses two independent foundries to manufacture its silicon-based products and two
independent foundries to manufacture its GaAs MESFET products. The foundries
that supply the Company's GaAs MESFET requirements are owned and operated by ITT
Industries, Inc. and TriQuint Semiconductor, Inc. ("TriQuint"), which are
competitors of the Company. Foundry capacity for GaAs products has been
difficult to obtain at times in the past. The Company is and will remain
dependent on a small number of independent foundries to manufacture and
 
                                        9
<PAGE>   13
 
deliver its products on a timely basis, to achieve acceptable manufacturing
yields and to offer competitive pricing to the Company. Accordingly, the failure
of such independent foundries to manufacture and deliver the Company's products
on a timely basis, to allocate to the Company sufficient capacity to meet the
Company's requirements, to achieve acceptable manufacturing yields or to offer
competitive pricing to the Company would have a material adverse effect on the
Company's business, financial condition and results of operations. Further, no
assurance can be given that the Company would be able to locate other foundries
to fabricate its products in the event of a loss of any current source of
supply.
 
     The Company uses independent vendors to package all of its integrated
circuits. The Company has encountered packaging quality problems with certain of
such vendors, particularly with regard to GaAs products. There can be no
assurance that the Company will not experience packaging problems in the future.
A delay or reduction in product shipment or reduced assembly yields would have a
material adverse effect on the Company's business, financial condition and
results of operations. See "-- International Sales and Operations" and
"Business -- Manufacturing, Packaging and Testing."
 
COMPETITION
 
     Competition in the markets for the Company's products is intense. The
Company faces competition from several companies primarily engaged in the
business of designing, manufacturing and selling silicon and GaAs MESFET RFICs,
as well as suppliers of discrete products such as transistors, capacitors and
resistors. The Company also faces competition from companies that have or may
develop GaAs HBT or other new fabrication processes. In addition, many of the
Company's existing and potential OEM customers manufacture or assemble wireless
communications devices and have substantial in-house technological capabilities.
Such OEMs currently may be developing, or may develop in the future, products
that compete directly with the Company's products. A decision by one or more
large OEM customers of the Company to design and manufacture integrated circuits
internally would have a material adverse effect on the Company's business,
financial condition and results of operations. The Company expects competition
in the future to increase. Increased competition could result in decreased
prices for the Company's products, reduced demand for the Company's products and
a reduction in the Company's ability to recover development engineering costs.
Any of these developments would have a material adverse effect on the Company's
business, financial condition and results of operations.
 
     Many of the Company's current and potential customers have entrenched
market positions, substantial internal manufacturing capacity, established
patents, copyrights, trade names, trademarks and intellectual property rights
and substantial technological capabilities. Most of the Company's current and
potential competitors, including ANADIGICS, Inc. ("ANADIGICS"), Motorola Inc.
("Motorola"), NEC Corp. ("NEC"), Philips N.V. ("Philips"), Rockwell
International Corp. ("Rockwell") and TriQuint, have significantly greater
financial, technical, manufacturing and marketing resources than the Company.
There can be no assurance that the Company will be able to compete successfully
with its existing or new competitors. See "Business -- Competition."
 
RAPID TECHNOLOGICAL CHANGE; DEPENDENCE ON DEVELOPMENT AND GROWTH OF WIRELESS
MARKETS
 
     The Company's prospects depend upon continued development and growth of
markets for wireless communications products and services, including cellular
telephony, PCS handsets, wireless LANs, wireless security systems and other
wireless applications. No assurance can be given regarding the rate at which the
markets for such products will develop or the Company's ability to produce
competitive products for such markets as they develop.
 
     The Company supplies RFICs almost exclusively for wireless applications.
The wireless markets currently are characterized by frequent introduction of new
products and services in response to evolving product and process technologies
and consumer demand for greater functionality, lower costs, smaller products and
better performance. Consequently, the Company has experienced a degree of
product design obsolescence. Because the demand of OEMs for improvements in
product performance is expected to increase, the Company believes that its
future success will depend in part upon its ability to continue to
 
                                       10
<PAGE>   14
 
improve its product designs and to develop new products based on emerging wafer
fabrication technologies. If a competing process technology emerges that permits
the fabrication of integrated circuits that are superior to the RFICs fabricated
under the existing processes available to the Company, and if the Company is
unable to design successfully products under such technology or to develop
competitive or alternative products that are economically viable and that can be
delivered in sufficient product quantity to OEMs at acceptable yields, the
Company's business, financial condition and results of operations would be
materially and adversely affected. Competition among the Company's target
customers is intense and thus many OEMs may be reluctant to implement new
technologies. Further, in each of the markets in which the Company competes,
prices of established products tend to decline significantly over time.
Developing these enhancements, new designs and technologies requires significant
investments by the Company in research and development efforts, and there can be
no assurance that funds for such investments will be available when needed on
acceptable terms or that such efforts will be successful. See
"Business -- Research and Development."
 
NEED FOR ADDITIONAL CAPITAL
 
     The Company will require substantial capital to construct its wafer
fabrication facility and to fund its operations and growth. The Company's wafer
fabrication facility is scheduled to be developed in two phases, the first of
which has a budgeted cost of $40 million and the second of which involves an
expansion of production capacity at a budgeted cost of $30 million. The Company
expects to use approximately $15 million of the net proceeds from this offering
to finance a portion of the cost of constructing the first phase of the
fabrication facility, and to finance the remainder of such phase with cash on
hand and previously obtained financing commitments. The Company's future capital
requirements will depend on many factors, including the actual cost of
constructing the new fabrication facility, whether demand for the Company's
products justifies the phased expansion of its facility, the timing and extent
of spending to support product development efforts and expansion of sales and
marketing, the timing of introductions of new products and market acceptance of
the Company's products. The Company expects that it may need to raise additional
equity or debt financing during 1998 to finance a portion of the cost of
constructing the second phase of the fabrication facility. However, there can be
no assurance that additional financing will not be required prior to such time.
There can be no assurance that additional equity or debt financing, if required,
will be available on acceptable terms or at all. See "Use of Proceeds" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
 
DEPENDENCE UPON KEY PERSONNEL
 
     The Company's success depends in part upon retaining the services of
certain technical, marketing, sales and management personnel. None of the
Company's employees has an employment agreement with the Company. The loss of
any key personnel would have a material adverse effect on the Company's
business, financial condition and results of operations. Further, the Company's
prospects depend upon its ability to attract qualified personnel for its
operations. The competition for qualified personnel is intense, and the number
of persons with experience, particularly in RF engineering, integrated circuit
design, wireless systems and technical marketing and support, is limited. There
can be no assurance that the Company will be able to attract, assimilate or
retain other skilled personnel in the future. Any inability on the part of the
Company to attract or retain additional key employees or the loss of one or more
of its current key employees would have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Management."
 
INTERNATIONAL SALES AND OPERATIONS
 
   
     Sales to customers located outside the United States accounted for
approximately 27%, 24% and 42% of total revenues for fiscal 1995, 1996 and 1997,
respectively. The Company expects that revenues derived from international sales
will continue to represent a significant portion of its total revenues.
International sales are subject to a variety of risks, including those arising
from currency fluctuations and restrictions, tariffs, trade barriers, taxes and
export license requirements. Because all of the Company's foreign sales are
currently denominated in U.S. dollars, the Company's products become less price
competitive in countries with
    
 
                                       11
<PAGE>   15
 
currencies that are low or are declining in value against the U.S. dollar. In
addition, there can be no assurance that the Company's international customers
will continue to accept orders denominated in U.S. dollars. If such customers do
not continue to accept orders denominated in U.S. dollars, the Company's
reported revenues and earnings would become more directly subject to foreign
exchange fluctuations. See Note 2 of Notes to Financial Statements.
 
     All of the packaging materials used to assemble the Company's integrated
circuits are supplied by, and all of the Company's products are assembled by,
independent circuit assembly vendors, most of which are located in Asia. Due to
its reliance on such foreign suppliers and assemblers, the Company is subject to
the risks of conducting business outside of the United States. These risks
include unexpected changes in, or impositions of, legislative or regulatory
requirements, delays resulting from difficulty in obtaining export licenses,
tariffs and other trade barriers and restrictions, and the burdens of complying
with a variety of foreign laws and other factors beyond the Company's control.
The Company also is subject to general geopolitical risks in connection with its
international operations, such as political, social and economic instability,
potential hostilities and changes in diplomatic and trade or business
relationships. Although the Company has not to date experienced any material
adverse effect on its operations as a result of such regulatory, geopolitical
and other factors, there can be no assurance that such factors will not
adversely affect the Company's operations in the future or require the Company
to modify its current business practices. The Company currently transacts
business with its foreign assemblers in U.S. dollars and consequently the cost
of the Company's packaging components, as well as assembly costs, would increase
in countries with currencies that are increasing in value against the U.S.
dollar. In addition, there can be no assurance that the Company's international
assemblers will continue to accept orders denominated in U.S. dollars. If such
assemblers do not continue to accept orders denominated in U.S. dollars, the
Company's costs would become more directly subject to foreign exchange
fluctuations.
 
INTELLECTUAL PROPERTY CLAIMS
 
     The Company's success depends in part on its ability to obtain patents,
trademarks and copyrights, maintain trade secret protection and operate its
business without infringing on the proprietary rights of third parties. See
"-- Dependence on TRW."
 
     The Company may be notified in the future that it is infringing patent or
other intellectual property rights of others, although there are no such pending
lawsuits against the Company or notices that the Company is infringing
intellectual property rights of others. No assurance can be given that in the
event of such infringement, licenses could be obtained on commercially
reasonably terms or that litigation will not occur. The failure to obtain
necessary license or other rights or the occurrence of litigation arising out of
such claims would have a material adverse effect on the Company's business,
financial condition and results of operations.
 
     In addition to patent and copyright protection, the Company also relies on
trade secrets, technical know-how and other unpatented proprietary information
relating to its product development and manufacturing activities which it seeks
to protect, in part, by confidentiality agreements with its employees and third
parties. There can be no assurance that these agreements will not be breached,
that the Company would have adequate remedies for any breach or that the
Company's trade secrets and proprietary know-how will not otherwise become known
or independently discovered by others. See "Business -- Intellectual Property."
 
GOVERNMENT REGULATION OF COMMUNICATIONS INDUSTRY
 
     The sale of products by customers who purchase the Company's products may
be materially and adversely affected by governmental regulatory policies, the
imposition of common carrier tariffs or taxation of telecommunications services.
Further, national governments control the allocation and use of radio
frequencies and may implement regulations or take other action that directly or
indirectly has a material adverse effect on the Company's business, financial
condition or results of operations.
 
CONCENTRATION OF STOCK OWNERSHIP
 
     Upon consummation of this offering, directors and executive officers of the
Company and their affiliates (including TRW) collectively will beneficially own
approximately 53.9% of the Common Stock (52.6% if the
 
                                       12
<PAGE>   16
 
   
Underwriters' over-allotment option is exercised in full), and TRW, the
Company's largest shareholder, will beneficially own approximately 31.1% of the
Common Stock (30.3% if the Underwriters' over-allotment option is exercised in
full). As a result, these shareholders will be able to exercise significant
influence over all matters requiring shareholder approval, including the
election of directors and approval of significant corporate transactions. TRW
has granted David A. Norbury, President and Chief Executive Officer of the
Company, an irrevocable proxy to vote 2,683,930 of the 4,621,487 shares of
Common Stock beneficially owned by TRW. Such proxy will expire if and when the
Company's fabrication facility becomes operational. See "Certain
Transactions -- TRW" and "Principal and Selling Shareholders."
    
 
NO PRIOR PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE
 
     Prior to this offering, there has been no public market for the Company's
Common Stock, and there can be no assurance that an active public market for the
Common Stock will develop or be sustained after this offering. The initial
public offering price will be determined by negotiation between the Company, the
Selling Shareholders and the representatives of the Underwriters. See
"Underwriting."
 
     The trading price of the Company's Common Stock could be subject to wide
fluctuations in response to quarterly variations in operating results, changes
in financial estimates by securities analysts, announcements of technological
innovations or new products by the Company or its competitors, or other events
or factors. In addition, the stock market has experienced extreme price and
volume fluctuations that have particularly affected the market prices for many
high technology companies. These broad market fluctuations may materially and
adversely affect the market price of the Company's Common Stock.
 
SUBSTANTIAL DILUTION
 
   
     Purchasers of the Common Stock offered hereby will incur immediate and
substantial dilution of approximately $7.22 per share in the net tangible book
value per share of the Common Stock from the initial public offering price. See
"Dilution."
    
 
SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Sales of the Company's Common Stock in the public market after this
offering could adversely affect the market price of the Company's Common Stock.
Following this offering, there will be 13,740,330 shares of Common Stock
outstanding, of which the 2,537,000 shares offered hereby will be freely
tradeable without restriction under the Securities Act of 1933, as amended (the
"Securities Act"), except for shares acquired in this offering by "affiliates"
of the Company, as that term is defined in Rule 144 under the Securities Act.
Upon expiration of the lock-up agreements 180 days after the date of this
Prospectus, approximately 8,519,400 additional shares of Common Stock will
become eligible for sale in the public market, subject to the provisions of Rule
144 or Rule 701. In addition, up to 1,111,111 shares of Common Stock could
become eligible for sale at such time if the TRW Convertible Note were to be
converted. Such lock-up agreements are subject to release at the discretion of
the representatives of the Underwriters. Moreover, the Company intends to file
registration statements under the Securities Act covering shares of Common Stock
reserved for issuance under stock option and stock purchase plans, including up
to 463,567 shares of Common Stock that were or may be issued upon the exercise
of stock options during 1997. Certain of the Company's shareholders have the
right to cause the Company to register their shares under the Securities Act and
to include their shares in any future registration of securities effected by the
Company under the Securities Act. See "Shares Eligible for Future Sale" and
"Description of Capital Stock -- Registration Rights."
    
 
ANTI-TAKEOVER AND CERTAIN OTHER PROVISIONS
 
     Certain provisions of the Company's articles of incorporation and bylaws
could have the effect of making it more difficult for a third party to acquire,
or of discouraging a third party from attempting to acquire, control of the
Company. These provisions include the ability of the Board of Directors to
designate the rights and preferences of Preferred Stock and issue such shares
without shareholder approval and the requirement of supermajority shareholder
approval of certain transactions with parties affiliated with the Company. Such
 
                                       13
<PAGE>   17
 
provisions could limit the price that certain investors might be willing to pay
in the future for shares of the Company's Common Stock. See "Description of
Capital Stock."
 
     Pursuant to an agreement among the Company, TRW and certain other
shareholders of the Company, TRW has agreed to refrain from taking certain
actions affecting the control of the Company for five years following this
offering. This agreement further provides, however, that in the event of an
offer by a third party to acquire all of the outstanding shares of the Company,
TRW will have a 30-day period in which to make a counterproposal on the same or
better terms and to have such proposal submitted to the Company's shareholders.
This right could have the effect of discouraging a third party from offering to
acquire all of the outstanding shares of the Company. See "Certain
Transactions -- TRW -- Standstill Agreement." In addition, under the terms of
its credit facility with Silicon Valley Bank, the Company is prohibited from
entering into mergers or acquisitions, undergoing a material change in ownership
or making dispositions of assets other than in the ordinary course of business.

                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of the 2,500,000 shares of
Common Stock offered by it hereby are estimated to be approximately $22.7
million assuming an initial public offering price of $10.00 per share and after
deducting the underwriting discount and estimated offering expenses
(approximately $26.2 million if the Underwriters' over-allotment option is
exercised in full). The Company will not receive any proceeds from the sale of
shares of Common Stock by the Selling Shareholders.
    
 
   
     The Company intends to use approximately $15 million of the net proceeds to
the Company to finance a portion of the cost of constructing the first phase of
a new GaAs HBT wafer fabrication facility that will be located adjacent to the
Company's existing facility in Greensboro, North Carolina. The wafer fabrication
facility is scheduled to be developed in two phases, the first of which has a
budgeted cost of $40 million and the second of which involves an expansion of
production capacity at a budgeted cost of $30 million. The Company expects to
finance the remainder of the first phase with cash on hand and previously
obtained financing commitments. The Company expects that it may need to raise
additional equity or debt financing during 1998 to finance a portion of the cost
of constructing the second phase of the fabrication facility. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
    
 
   
     The Company intends to use a portion of the net proceeds to the Company to
repay all outstanding indebtedness under its credit facility with Silicon Valley
Bank, which indebtedness consists of approximately $350,000 outstanding at March
31, 1997 under a revolving line of credit that bears interest at prime plus
0.75% and matures in December 1997 and approximately $295,000 outstanding at
March 31, 1997 for separate term loans made under an equipment line of credit
that bear interest at prime plus 1.5% and mature 36 months from the date of each
loan.
    
 
     The remaining net proceeds will be used for working capital and general
corporate purposes, which may include expansion of the Company's facilities.
Pending application of net proceeds as set forth above, the Company intends to
invest the net proceeds in short-term, investment grade debt securities.
 
                                DIVIDEND POLICY
 
   
     The Company has never declared or paid any cash dividends on its capital
stock and does not anticipate paying any cash dividends in the foreseeable
future. The Company intends to retain its future earnings, if any, to fund the
development and growth of its business. Any future decision concerning the
payment of dividends on the Common Stock will depend upon the earnings,
financial condition and capital requirements of the Company, as well as such
other factors deemed relevant by the Board of Directors, in its sole discretion.
Under the terms of the TRW Convertible Note, the Company is prohibited from
authorizing, declaring or paying any dividends until the Company's wafer
fabrication facility becomes operational. Under the terms of its credit facility
with Silicon Valley Bank, the Company is prohibited from paying any dividends or
making any other distributions or payments on account, or in redemption,
retirement or purchase, of any of its capital stock. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."

                                 CAPITALIZATION
 
   
     The following table sets forth the capitalization of the Company as of
March 31, 1997 on an actual, pro forma and pro forma as adjusted basis. The pro
forma capitalization gives effect to the conversion of outstanding shares of
Preferred Stock into an aggregate of 7,954,320 shares of Common Stock and the
pro forma as adjusted capitalization gives effect to such conversion and the
sale of 2,500,000 shares of Common Stock by the Company in this offering and the
application of the estimated net proceeds therefrom, after deducting the
underwriting discount and estimated offering expenses. See "Use of Proceeds."
This information should be read in conjunction with the Company's Financial

(1) Consists of 7,954,320 shares of Preferred Stock that will automatically
     convert into 7,954,320 shares of Common Stock upon the consummation of this
     offering.
    
   
(2) For financial reporting purposes, the Company records deferred compensation
     expense with respect to stock options granted at exercise prices below the
     deemed fair market value of the underlying Common Stock in an amount equal
     to the difference between the exercise price of such options and the deemed
     fair market value of the underlying Common Stock at the time of grant.
     Deferred compensation expense is amortized ratably over the vesting period
     of the related options. See Notes 2 and 10 of Notes to Financial
     Statements.
    
   
(3) Excludes (i) 1,111,111 shares of Common Stock issuable upon the conversion

     shares of Common Stock issuable upon exercise of options outstanding at

                                    DILUTION
 
   
     At March 31, 1997, the pro forma net tangible book value of the Company was
approximately $15.6 million or $1.39 per share. "Pro forma net tangible book
value" per share is equal to the Company's total tangible assets (before the
offering) less total liabilities divided by the total number of shares of Common
Stock outstanding on a pro forma basis, giving effect to the conversion of all
outstanding shares of Preferred Stock. After giving effect to the sale of the
2,500,000 shares of Common Stock offered by the Company hereby at an assumed
initial public offering price of $10.00 per share and after deducting the
underwriting discount and estimated offering expenses, the pro forma net
tangible book value of the Company at March 31, 1997 would have been $38.2
million or $2.78 per share. This represents an immediate increase in the pro
forma net tangible book value of $1.39 per share to existing shareholders and an
immediate dilution of $7.22 per share to purchasers in this offering. The

     The foregoing tables assume no exercise of the Underwriters' over-allotment

with the "Management's Discussion and Analysis of Financial Condition and

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
     The following discussion and analysis should be read in conjunction with
"Selected Financial Data" and the Company's Financial Statements and Notes
thereto included elsewhere in this Prospectus. Except for the historical
information contained herein, the discussion in this Prospectus contains certain
forward-looking statements that involve risks and uncertainties, such as
statements of the Company's plans, objectives, expectations and intentions. The
cautionary statements made in this Prospectus should be read as being applicable
to all related forward-looking statements wherever they appear in this
Prospectus. The Company's actual results could differ materially from those
discussed herein. Factors that could cause or contribute to such differences
include those discussed in "Risk Factors," as well as those discussed elsewhere
herein.
 
OVERVIEW
 
   
     The Company designs, develops and markets RFICs for wireless communications
applications. These applications include cellular and personal communication
services ("PCS"), cordless telephony, wireless local area networks ("wireless
LANs"), wireless local loop ("WLL"), industrial radios, wireless security and
remote meter reading. To date, a significant portion of the Company's revenues
has been attributable to the sale of RFICs used in cellular telephones and PCS
handsets. The Company offers products fabricated under three distinct process
technologies: GaAs HBT, GaAs MESFET and silicon bipolar transistor. For fiscal
1996 and fiscal 1997, approximately 58% and 85%, respectively, of the Company's
revenues were derived from the sale of GaAs HBT products. The Company may
continue to rely heavily on sales of GaAs HBT products in future periods.
    
 
     Prior to fiscal 1995, the Company was in the development stage. After
emergence from the development stage, the Company has experienced a significant
increase in product revenues. In February 1995, the Company and QUALCOMM entered
into a development contract for certain RFICs to be used by QUALCOMM in its CDMA
handsets. During fiscal 1996, the Company began shipping products developed
under that contract in commercial quantities, and revenues increased
significantly. Due primarily to the Company's inability to meet requested
delivery times and quantity requirements, QUALCOMM has determined to produce
internally certain components and to look to other sources for certain other
components to replace all products currently purchased from the Company.
Accordingly, the Company expects sales to QUALCOMM to cease in May 1997.
Although the Company is attempting to replace the sales previously made to
QUALCOMM with sales to other customers, no assurance can be given that it will
be able to do so. Further, the Company's ability to supply GaAs HBT components
remains subject to capacity constraints, and the relatively lengthy design cycle
for custom RFICs makes it difficult to quickly commence high volume sales to new
customers. As a result, the Company currently does not expect growth in
revenues, if any, to be significant over the next two fiscal quarters.
 
     Product revenue is recognized when shipped, and all product sales are
denominated in U.S. dollars. The Company derives its revenues from the sale of
standard and custom-designed products. Custom-designed products are usually
developed for volume production orders from large OEMs and normally are
manufactured on an exclusive basis for the originating customer for a negotiated
period of time. Once exclusivity periods expire, the Company attempts to migrate
custom products rapidly into the standard product category in order to broaden
its customer base and leverage its design and product development expenditures.
 
     The Company currently derives a majority of its revenues from the sale of
custom-designed products. However, the Company's strategy is to maintain a
balanced product mix between standard and custom-designed products so as to
reduce the Company's reliance on individual customers and product orders.
 
   
     A relatively limited number of customers historically have accounted for a
significant portion of the Company's revenues, and the composition of the
Company's most significant customers has varied significantly from period to
period. In fiscal 1997, sales to QUALCOMM and Samsung accounted for 32.1% and
23.4%, respectively, of revenues, and sales to the Company's five most
significant customers in the aggregate accounted for 73.0% of revenues. In
fiscal 1996, sales to QUALCOMM and Cincinnati Microwave accounted for 31.3% and
11.9% of revenues, respectively, and sales to the Company's five most
significant customers in
    
 
                                       19
<PAGE>   23
 
   
the aggregate accounted for 60.7% of revenues. Further, only two of the
Company's five most significant customers for fiscal 1996 were among the
Company's five most significant customers for fiscal 1997. Because the markets
for wireless devices are characterized by the presence of a relatively small
number of large OEMs that place high-volume orders, the Company expects that
sales of its products to a limited number of customers will continue to account
for a high percentage of its revenues in the future and that the composition of
the Company's most significant customers will continue to change significantly
from period to period.
    
 
     The Company currently uses independent foundries to manufacture and
assemble all of its RFICs. The Company generally contracts for the fabrication
of wafers and the assembly and packaging of circuits at negotiated prices
pursuant to purchase orders or short-term contracts. Substantially all of the
Company's integrated circuits are assembled by vendors located in Asia, and all
assembly contracts are denominated in U.S. dollars. All of the Company's final
products are tested in the Company's facilities in Greensboro, North Carolina.
 
   
     The Company historically has experienced significant fluctuations in gross
profit margins. For the fiscal years ended March 31, 1995, March 31, 1996 and
March 31, 1997, the Company's gross profit margins were approximately 28.0%,
21.5% and 45.1%, respectively. The Company believes that its gross profit
margins have been significantly affected by manufacturing, assembly and test
yields. In particular, in fiscal 1996, the Company experienced poor
manufacturing, assembly and test yields during the initial stage of developing a
CDMA chipset for QUALCOMM. The Company believes the poor yields related to the
development of such chipset were attributable to the fact that such chipset was
used in one of the first CDMA phones designed for commercial production, which
caused several unexpected changes in product specifications during development
and the use of very precise specification requirements for final products.
Further, QUALCOMM was the first large OEM to order from the Company significant
volumes of RFICs, and the related increase in production volumes initially
resulted in an unacceptable amount of product scrap. Although the Company
believes it has learned how to better control product yields for new products,
there can be no assurance that future operating results will not be affected by
low manufacturing, assembly and test yields. Further, the Company sells products
in intensely competitive markets, and the Company believes that downward
pressure on average selling prices will occur in the future.

  Fiscal 1997 Compared to Fiscal 1996
    
 
   
     Revenues.  Revenues increased 203% from $9.5 million for the year ended
March 31, 1996 to $28.8 million for the year ended March 31, 1997. The increase
primarily reflected an overall increase in the volume
    
 
                                       20
<PAGE>   24
 
   
of products shipped to existing and new customers, primarily in the cellular and
PCS handset markets. The Company sells products in intensely competitive
markets, and the Company believes that downward pressure on average selling
prices will occur in the future. For the years ended March 31, 1996 and March
31, 1997, a significant portion of the Company's revenues was attributable to
sales of RFICs used in cellular and PCS handsets, and the Company expects this
trend to continue in the future. In addition, for the year ended March 31, 1997,
approximately 85% of the Company's revenues was attributable to the sale of GaAs
HBT products, and the Company may remain dependent upon GaAs HBT products to
generate a substantial portion of its future revenues. Engineering revenues
accounted for 13.7% of revenues for the year ended March 31, 1996 compared to
3.3% of revenues for the year ended March 31, 1997. For the year ended March 31,
1997, sales to QUALCOMM and Samsung accounted for 32.1% and 23.4%, respectively,
of revenues. Due primarily to the Company's inability to meet QUALCOMM's
requested delivery times and quantity requirements, QUALCOMM has determined to
produce internally certain components and to look to other sources for other
components to replace all products currently purchased from the Company.
Accordingly, the Company expects sales to QUALCOMM to cease in May 1997.
    
 
   
     Gross profit.  Gross profit margin increased from 21.5% for the year ended
March 31, 1996 to 45.1% for the year ended March 31, 1997. The increase was
primarily attributable to an increase in production volumes during the year
ended March 31, 1997, a reduction in average wafer costs primarily attributable
to quantity discounts, and improvements in manufacturing, assembly and test
yields, which reduced scrap and lowered the per unit cost of goods sold. The
Company also experienced favorable product sales mix and pricing for the year
ended March 31, 1997.
    
 
   
     During the year ended March 31, 1997, the Company increased its inventory
allowance by approximately $766,000, and at March 31, 1997 the Company's
inventory allowance of $847,000 represented approximately 8.4% of the gross cost
of inventories. As indicated in Note 2 of Notes to Financial Statements, the
Company's inventories are stated at the lower of cost or market determined using
the average cost method, and the Company provides for potential obsolete or slow
moving inventory based on management's analysis of inventory levels and future
sales forecasts. The increase in the Company's inventory allowance during the
year ended March 31, 1997 was primarily attributable to the significant increase
in sales and corresponding increase in inventory levels during such period, the
concentrated nature of the Company's customer base, which has caused the Company
to make significant investments in certain products to meet certain of its large
OEM customers' high volume requirements, and the uncertain effect of
technological and product changes on the wireless products manufactured by the
Company's customers.
    
 
   
     Research and development.  Research and development expenses increased
45.5% from $4.2 million for the year ended March 31, 1996 to $6.2 million for
the year ended March 31, 1997. The increase was primarily attributable to
increased salaries and benefits related to increased headcount and additional
spending on development mask sets, wafers and prototype assembly for both
standard and custom-designed products. As a result of revenue growth, research
and development expenses as a percentage of revenues decreased from 44.6% for
the year ended March 31, 1996 to 21.4% for the year ended March 31, 1997.
    
 
   
     General and administrative.  General and administrative expenses increased
13.5% from $1.2 million for the year ended March 31, 1996 to $1.4 million for
the year ended March 31, 1997. The increase was attributable primarily to
increased salaries and benefits related to headcount increases. General and
administrative expenses as a percentage of revenues decreased from 12.9% for the
year ended March 31, 1996 to 4.8% for the year ended March 31, 1997.
    
 
   
     Marketing and selling.  Marketing and selling expenses increased 106.9%
from $1.8 million for the year ended March 31, 1996 to $3.8 million for the year
ended March 31, 1997. The increase was primarily attributable to increased
commissions reflecting the increase in sales during fiscal 1997 and, to a lesser
degree, increased salaries and benefits relating to increased headcount and
additional spending on promotional activities. Marketing and selling expenses as
a percentage of revenues decreased from 19.1% for the year ended March 31, 1996
to 13.1% for the year ended March 31, 1997.

     Other income (expense), net.  Other income (expense), net increased from
$56,000 for the year ended March 31, 1996 to $114,000 for the year ended March
31, 1997. The increase was principally attributable to higher interest income
earned on higher average cash balances during the year ended March 31, 1997.
    
 
   
     Income tax expense.  The effective tax rate for the year ended March 31,
1997 was 6.2%, which is less than the federal and state statutory rate of 40%
due to the use of net operating loss carryforwards. The Company did not provide
for income taxes in the year ended March 31, 1996 as a result of the loss
incurred in such fiscal year.
    
 
  Fiscal 1996 Compared to Fiscal 1995
 
   
     Revenues.  Revenues increased 464% from $1.7 million for the year ended
March 31, 1995 to $9.5 million for the year ended March 31, 1996. The increase
in total revenues for the year ended March 31, 1996 was primarily due to an
increase in volume principally related to increased product shipments to OEMs in
the cellular and cordless telephones, PCS and industrial radio markets. For the
year ended March 31, 1996, sales to QUALCOMM and Cincinnati Microwave accounted
for 31.3% and 11.9%, respectively, of revenues. Engineering revenues as a
percentage of revenues were 13.7% for the year ended March 31, 1996 compared to
25.7% for the year ended March 31, 1995.
    
 
   
     Gross profit.  Gross profit margin decreased from 28.0% for the year ended
March 31, 1995 to 21.5% for the year ended March 31, 1996. This decrease was
primarily attributable to poor manufacturing, assembly and test yields primarily
associated with custom-designed products developed for QUALCOMM, which was the
first high volume OEM to order significant quantities of RFICs from the Company.
    
 
     Research and development.  Research and development expenses increased from
$2.8 million for the year ended March 31, 1995 to $4.2 million for the year
ended March 31, 1996. The increase was attributable primarily to an increase in
salaries related to increased headcount and an increase in expenditures on
development mask sets, wafers and prototype assembly related to increased
developmental activities and development contracts with QUALCOMM and other
customers. Research and development expenses decreased as a percentage of total
revenues from 168% for the year ended March 31, 1995 to 44.6% for the year ended
March 31, 1996.
 
   
     General and administrative.  General and administrative expenses increased
97.7% from $620,000 for the year ended March 31, 1995 to $1.2 million for the
year ended March 31, 1996. The increase was attributable primarily to increased
bad debt expense and salaries and benefits related to increased headcount. The
Company reserved $490,000 for bad debts during the year ended March 31, 1996
related to outstanding receivable balances from two specific customers, most of
which was subsequently recovered. General and administrative expenses as a
percentage of revenues decreased from 36.7% for the year ended March 31, 1995 to
12.9% for the year ended March 31, 1996.
    
 
   
     Marketing and selling.  Marketing and selling expenses increased 54.0% from
$1.2 million for the year ended March 31, 1995 to $1.8 million for the year
ended March 31, 1996. The increase was due primarily to increased salaries and
benefits related to increased headcount along with increased promotional
activities and commissions. Marketing and selling expenses as a percentage of
revenues decreased from 69.9% for the year ended March 31, 1995 to 19.1% for the
year ended March 31, 1996.
    
 
     Other income (expense), net.  Other income (expense), net increased from
$41,000 for the year ended March 31, 1995 to $56,000 for the year ended March
31, 1996. This increase was due primarily to higher interest income for the year
ended March 31, 1996.
 
     Income tax expense.  The Company did not provide for income tax expense in
fiscal 1995 or fiscal 1996 because the Company incurred losses for such fiscal
years.

     Revenues increased each quarter in fiscal 1996 as a result of increased
unit product shipments. Revenues generally increased in each quarter of fiscal
1997 with the exception of the fourth quarter. The increase in revenues during
1997 reflects increased unit shipments to the cellular and PCS handset market
segments, and the decrease in revenues in the fourth quarter of fiscal 1997
reflects a decline in sales to QUALCOMM. Gross profit margins experienced wide
fluctuations throughout the eight quarters. Gross profit margin reached a low of
10.4% in the fourth quarter of fiscal 1996 due to high material scrap caused by
low production test yields related to the Company's development contract with
QUALCOMM. Gross profit margin was the highest in the second quarter of fiscal
1997 because of favorable product sales mix and pricing, improved manufacturing,
assembly and test yields and increased absorption of manufacturing overhead due
to higher sales volume and a reduction in average wafer costs. The Company's
research and development expense increased over the two-year period to $1.8
million in the fourth quarter of fiscal 1997. The Company's marketing and
selling and general and administrative expenses generally increased over the
two-year period to $1.2 million and $431,000, respectively, in the fourth
quarter of fiscal 1997, reflecting increased salaries and benefits related to
increased headcount, commissions, promotional activities and general corporate
expenses.
    
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Historically, the Company's cash flow from operations has been insufficient
to satisfy the Company's cash requirements. To date, the Company has funded its
operations primarily through the private sale of equity and debt securities,
bank borrowings and equipment leases. Since fiscal 1994, the Company's primary
cash requirements have been to finance operating activities, to purchase
property and equipment and to repay capital lease obligations and bank
borrowings and interest.
 
   
     The Company and Silicon Valley Bank have entered into a secured credit
facility that includes a $7 million working capital revolving line of credit and
a $2 million equipment line of credit. Both lines of credit have an expiration
date of December 19, 1997. Borrowings under the revolving line of credit can be
made from time to time in an amount not to exceed 80% of eligible accounts
receivable and bear interest at prime plus 0.75%, payable monthly. Borrowings
under the equipment line of credit are converted into term loans, repayable in
36 equal monthly installments from the date of advance, and bear interest at
prime plus 1.5%. The credit facility requires, among other things, that the
Company maintain certain amounts of tangible net worth and certain ratios with
regard to liquidity and debt to equity. At March 31, 1997, there was
approximately $645,000 outstanding under such facility. The Company intends to
repay the outstanding indebtedness under such facility with a portion of the
proceeds from this offering. See "Use of Proceeds."
    
 
     In February 1997, the Company entered into an equipment lease agreement
with an equipment financing company, pursuant to which such financing company
agreed to finance the lease of equipment having an aggregate cost not in excess
of $10 million. The terms of such lease agreement provide for a lease term of 52
months and monthly lease payments of 2.41% of the cost of the equipment leased,
subject to adjustment by such financing company proportionately to the change in
the weekly average of interest rates of five-year U.S. treasury securities.
Pursuant to the lease agreement, the Company has issued to such financing
company a warrant for 41,322 shares of Common Stock and has agreed to issue to
such financing company, upon the lease under the agreement of equipment having
an aggregate cost of $5 million, a warrant to purchase an additional 41,323
shares of Common Stock. Both warrants are exercisable at $9.00 per share and
expire five years from their respective dates of issuance. The Company
anticipates using such lease agreement to finance the acquisition of wafer
fabricating, clean room and other testing and manufacturing equipment to be used
in its proposed fabrication facility.
 
   
     In February 1997, the Company entered into agreements with a financing
company providing for the financing of the clean room facility at the Company's
proposed wafer fabrication facility and for the sale and lease-back of such
facility between the Company and the financing company when the facility has
been completed. The facility has an aggregate cost of approximately $2.5
million. The terms of the lease agreement provide for a term of 60 months from
the date the facility is completed, and for monthly lease payments calculated by
applying a lease investment return factor of 9.25% to the aggregate amount of
the cost of the facility and the interest accrued on such amount at an annual
rate of 9.25% prior to installation. The Company has the option to purchase the
facility at the end of the lease term for the lesser of the fair market value of
the equipment at such time or 10% of the original cost of the facility.

     The Company entered into a lease agreement in October 1996 with the owner
of the real estate on which the Company's wafer fabrication facility is proposed
to be built that provides for the construction of the facility. The lease
agreement has a term of 15 years from the completion of the building with two
10-year renewal options. The initial rental payment under the lease is to be
calculated on a per-square-foot basis based on the per-square-foot cost of the
construction of the building. To the extent that such construction cost is any
amount up to $90.00 per square foot, the annual lease payment per square foot
will be 12.5% of such cost. All of such construction cost in excess of $90.00
per square foot, up to an aggregate cost of $170.00 per square foot, will be
amortized over the initial 15-year term of the lease at a rate of 12%.
Construction costs in excess of $170.00 per square foot are to be paid by the
Company directly to the contractors. The initial rent under the lease will
increase by 4.5% after three years, and every three years thereafter by a
percentage equal to 80% of the percentage increase in the Consumer Price Index
during the immediately preceding three years. The Company has agreed under the
lease to provide guarantees in secured cash or corporate guarantees for all
construction costs in excess of $80.00 per square foot up to $170.00 per square
foot. The Company currently anticipates that the fabrication facility will
comprise approximately 50,000 square feet, will be constructed at an aggregate
cost of approximately $8.5 million and will require the Company to make
guarantees in secured cash or corporate guarantees of approximately $4.6
million, which must be made at such time as the aggregate cost of such facility
exceeds $80.00 per square foot. The actual cost of the Company's fabrication
facility is subject to a number of factors outside of the Company's control, and
such cost may be in excess of the Company's estimates. See "Risk
Factors -- Construction and Operation of Fabrication Facility."
    
 
   
     The Company will require substantial capital to construct its wafer
fabrication facility and to fund its operations and growth. The Company's wafer
fabrication facility is scheduled to be developed in two phases, the first of
which has a budgeted cost of $40 million, comprising facility, equipment and
other costs of $14 million, $22 million and $4 million, respectively, and the
second of which involves an expansion of production capacity at a budgeted cost
of $30 million, consisting of additional facility, equipment and other costs of
$8 million, $16 million and $6 million, respectively. The Company has obtained
financing for approximately $6.4 million of its phase one facility costs
(consisting of the clean room financing and real estate lease agreement
discussed above) and approximately $10 million of its phase one equipment costs
(consisting of the equipment lease agreement discussed above). The Company
intends to use approximately $15 million of the net proceeds to the Company from
this offering and cash on hand to finance the remaining portion of the cost of
constructing the first phase of the fabrication facility. The Company currently
believes its fabrication facility will be operating at commercial levels (i.e.,
capable of producing approximately 2,500 wafers per year) in the second half of
1998. Further, the Company believes that upon completion of the first phase of
construction, its fabrication facility will have a capacity of 10,000 wafers per
year and that, upon completion of its second phase of construction, such
facility will have a capacity of 25,000 wafers per year. See "Risk
Factors -- Construction and Operation of Fabrication Facility." The Company's
future capital requirements will depend on many factors, including the actual
cost of constructing the new fabrication facility, whether demand for the
Company's products justifies the phased expansion of its facility, the timing
and extent of spending to support product development efforts and expansion of
sales and marketing, the timing of introductions of new products and market
acceptance of the Company's products. The Company expects that it may need to
raise additional equity or debt financing during 1998 to finance a portion of
the cost of constructing the second phase of the fabrication facility. However,
there can be no assurance that additional financing will not be required prior
to such time. Further, there can be no assurance that additional equity or debt
financing, if required, will be available on acceptable terms or at all. Under
the terms of the TRW Convertible Note, the Company is prohibited from incurring
debt in excess of $25 million, other than debt incurred for the construction and
operation of the wafer fabrication facility.

INTRODUCTION
 
     The Company designs, develops and markets proprietary radio frequency
integrated circuits ("RFICs") for wireless communications applications such as
cellular and PCS, cordless telephony, wireless LANs, WLL, industrial radios,
wireless security and remote meter reading. The Company offers a broad array of
products, including amplifiers, mixers, and modulators/demodulators that
represent a substantial majority of the RFICs required in wireless subscriber
equipment. The Company designs products using three distinct process
technologies: GaAs HBT, GaAs MESFET and silicon bipolar transistor. The Company
believes that for certain applications, GaAs HBT devices offer advantages in
terms of linearity, efficiency, reduced system complexity and size.
 
     TRW is currently manufacturing all of the Company's GaAs HBT products and
has granted the Company a license to use its GaAs HBT process to design products
for commercial wireless applications. Through its relationship with TRW, the
Company has become a leading commercial supplier of GaAs HBT RFICs. The
Company's GaAs HBT power amplifiers and small signal devices have been designed
into advanced subscriber equipment manufactured by leading OEMs such as
QUALCOMM, Nokia, Hyundai Electronics Industries Co. Ltd. ("Hyundai"), Samsung,
Motorola and LG Information and Communications, Ltd. ("LG"). The Company also
offers GaAs MESFET and silicon components through a delivery strategy called
Optimum Technology Matching(R) to complement its GaAs HBT products. Optimum
Technology Matching(R) allows the Company to offer RFIC solutions, on a
component by component basis, that best fulfill OEMs' performance, cost and
time-to-market requirements.
 
INDUSTRY BACKGROUND
 
     The wireless communications industry has grown rapidly over the past decade
as cellular, paging, PCS and other emerging wireless communications services
have become widely available and increasingly affordable. Technological
advances, changes in telecommunications regulations and the allocation and
licensing of additional radio spectrum have helped fuel this growth worldwide
and have led not only to the development of competing wireless communications
services, but also to the development of new and emerging wireless applications,
including second generation digital cordless telephony, wireless LANs, WLL,
wireless security and remote meter reading. As wireless usage grows, wireless
service providers continue to improve the quality and functionality of the
services they offer and seek to offer greater bandwidth for increased capacity.
 
     To expand capacity from first generation cellular communications networks,
certain national governments have made available less congested frequency bands
for new wireless communications services. In the United States, the Federal
Communications Commission (the "FCC") has allocated and auctioned 10 MHz and 30
MHz portions of spectrum in the 1850 to 1990 MHz range for PCS, and allocated
broad band spectrum in the 2.4 GHz range for wireless LANs. Capacity and
functionality also are being addressed by the wireless industry's movement from
wireless networks that use analog signal modulation techniques to wireless
networks that use digital signal modulation techniques. As compared to analog
technologies, digital technologies generally provide improved signal quality,
facilitate the transmission of both voice and data and improve capacity by
allowing the transmission of more information in a smaller amount of frequency
space. These digital technologies place a premium on linear power amplification,
which can translate into higher quality signals.
 
     The wireless communications markets are characterized by a proliferation of
different air interface signal transmission standards in different parts of the
world, including analog standards, such as Advanced Mobile Phone Service
("AMPS") and Total Access Communications Systems ("TACS"), digital standards,
such as Time Division Multiple Access ("TDMA") and CDMA, and certain hybrid
standards. For PCS, the FCC has approved seven different air interface
standards. The handsets designed for each air interface standard generally
require unique RF and baseband integrated circuit solutions that must be
designed to meet the demands of subscriber equipment users for greater
functionality, smaller and lighter equipment, longer battery
 
                                       26

life and better security, all at reduced costs. As a result of these technical
challenges and end user demands, it has become increasingly difficult for OEMs
of subscriber equipment to develop and supply all the required components in a
timely and cost-effective manner. This has caused some OEMs to rely increasingly
on third party value-added technology providers that have the component and
systems level expertise to design and the production capacity to supply these
solutions. In addition, new entrants to the wireless subscriber equipment
market, such as large consumer electronics companies, tend to be less vertically
integrated than established OEMs, and thus must rely even more on third party
suppliers. This technology outsourcing trend is particularly evident in the RF
segment of the equipment due to the scarcity of RFIC engineers and the design
complexity of the technology.
 
  RF Overview
 
     A typical subscriber device for wireless personal communications, such as a
handset, contains digital, baseband and RF components. Digital components
control the overall circuitry and encrypt the voice or other data intended for
transmission and reception, while baseband components are used to process
signals into or from their original electrical form (low frequency analog voice
or data). RF components, such as amplifiers, mixers, attenuators, switches,
modulators, demodulators, oscillators and frequency synthesizers, convert,
switch, process and amplify the high frequency signals that carry the
information to be transmitted or received.
 
     RF technology presents different engineering challenges than standard
semiconductor design. In general, digital and baseband semiconductor design
engineers create standard semiconductor circuit designs by combining "cells"
that previously have been evaluated and characterized. Because cells have
predictable performance, the design engineer can use computers to automate the
design process, which helps accelerate the development of these components. Each
RF component, however, has distinctly different characteristics that influence
overall system performance in complex ways. Instead of having stable inputs and
outputs, the RF circuit characteristics can drift based on process variations,
temperature, power supply and other variables. As a result, performance
characteristics are unique for each device, and the RF engineer must evaluate
and develop new designs on a continuous basis for each system performance level
and air interface standard. In addition to being skilled in semiconductor
circuit design, the RF circuit designer must have a thorough understanding of
signal processing principles, must understand the totality of the system for
which the device is intended and must be able to create designs that function
within the unique parameters of different wireless system architectures. As RF
technology has moved from discrete components to integrated circuit solutions,
the scarcity of engineers with both integrated circuit design and RF expertise
has become more pronounced.
 
  RF Device Technology
 
     In early generations of wireless communications equipment, individually
packaged discrete components were mounted on circuit boards to form complex
circuits used to transmit and receive RF signals. Size, reliability and cost
concerns ultimately led to a move from discrete devices to silicon-based
integrated circuits. The use of silicon integrated circuits in high frequency
wireless technologies, however, has been limited because of decreased operating
performance generally at frequencies higher than approximately 1 GHz. In
particular, at high frequencies silicon integrated circuits consume more power,
have relatively high noise and distortion parameters and create excess heat.
 
     Within the last decade, GaAs semiconductor technology has emerged as an
effective alternative or complement to silicon technology in many high
performance RF applications. GaAs has inherent physical properties that allow
electrons to move up to five times faster than in silicon, which permits the
manufacture of GaAs devices that operate at much higher speeds than silicon
devices or at the same speeds with lower power consumption. This is particularly
important in battery powered portable applications such as handsets. Moreover,
the semi-insulating GaAs substrate significantly reduces some of the unwanted
parasitic effects of the conductive silicon substrate that cause its performance
to degrade at high frequencies.
 
     GaAs integrated circuits were first implemented using a type of transistor
known as MESFET. While GaAs MESFET integrated circuits have become accepted for
many high frequency applications, these devices have certain limitations. In
particular, for power amplifiers used in digital systems, it is important to
have a
 
                                       27
<PAGE>   31
 
linear signal (i.e., one that is not altered or distorted when amplified). It is
difficult for GaAs MESFET devices to meet high linearity performance criteria
without sacrificing other performance criteria. In addition, GaAs MESFET power
amplifiers generally require both a positive and negative power supply for power
stages, which requires the inclusion of additional components or circuitry and a
corresponding increase in device size and complexity. Moreover, the lateral
structure of GaAs MESFET devices hinders the ability to shrink the device size
to enhance manufacturing yields and reduce costs. A different type of GaAs
transistor known as an HBT, which has been used in military and space
applications over the past decade, has emerged recently in commercial RF
applications.
 
THE RF MICRO DEVICES SOLUTION
 
   
     The Company is a leading supplier of GaAs HBT RFICs for commercial wireless
applications based on sales. The Company's GaAs HBT products include power
amplifiers and small signal devices that have been designed into advanced
subscriber handsets manufactured by leading OEMs such as QUALCOMM, Nokia,
Hyundai, Samsung, Motorola and LG. In addition to the advantages that GaAs
provides over silicon in terms of speed, efficiency and the ability to operate
at high frequencies, the Company believes that GaAs HBT components offer the
following benefits over GaAs MESFET devices in comparable applications:
    
 
          - Efficiency -- Efficiency is a measure of RF power output as a
     percentage of battery power consumed by the device. The Company believes
     its GaAs HBT power amplifiers are more efficient and use less power to
     transmit the same output power than comparable GaAs MESFET devices.
     Increased efficiency can translate into improved battery life and increased
     talk time.
 
          - Linearity -- Linearity is a measure of the distortion of a signal as
     a result of the amplification of the signal. The Company believes GaAs HBT
     products have higher breakdown voltages and smaller and more constant
     base-collector capacitance than comparable GaAs MESFET devices, which
     results in better linearity. Improved linearity can translate into a higher
     quality signal, which is important for wireless networks using digital air
     interface standards such as TDMA and CDMA.
 
          - Complexity -- GaAs HBT transistors are bipolar devices that require
     only a single polarity power supply, while GaAs MESFET transistors
     generally require both a positive and negative power supply, which results
     in the need to include a negative voltage generator and other additional
     components or circuitry. As a result, GaAs HBT system architectures are
     simpler and easier to design, which can translate into reduced component
     costs and smaller equipment.
 
          - Size -- GaAs MESFET devices have a lateral or horizontal design
     structure while GaAs HBT devices have a more vertical structure. The
     Company believes that GaAs HBT circuits can be made smaller than GaAs
     MESFET devices, enabling more die per wafer, which can increase
     manufacturing yields and translate into reduced costs.
 
     In addition to its expertise in GaAs HBT process technology, the Company's
design engineers, test engineers and marketing personnel are experienced in
designing and delivering RFICs based on silicon bipolar and GaAs MESFET
technologies. As a result, the Company is able to offer a broad array of
standard and custom-designed RF solutions through a delivery strategy called
Optimum Technology Matching(R). Optimum Technology Matching(R) allows the
Company to offer OEM customers RFIC solutions on a component-by-component basis
that best fulfill the OEMs' performance, cost and time-to-market requirements.
Across these three semiconductor technologies, the Company offers more than 60
products that have a wide range of applications.
 
     The Company's circuit design staff is continually developing RFIC design
solutions for new and emerging wireless applications. The Company's research and
development activities include not only new circuit designs, but also the
development and refinement of proprietary design tools and models to facilitate
new product development. Moreover, the Company is continually evaluating test RF
circuits under emerging semiconductor process technologies to augment its
Optimum Technology Matching(R) program and to meet its customers' future
wireless equipment needs.

STRATEGY
 
     The Company's objective is to be the leading worldwide supplier of RFICs
for a broad range of commercial wireless applications. To meet this objective,
the Company has developed a focused strategy, the key elements of which include:
 
          Focus on Wireless Markets.  Since the Company's formation in 1991, it
     has focused its efforts almost exclusively on the design, development and
     sale of RFICs to participants in the commercial wireless markets. The
     Company has developed and sold integrated circuits for a broad range of
     applications within these markets, including cellular and PCS, cordless
     telephony, industrial radios, wireless LANs, WLL, wireless security and
     wireless utility meter reading. The Company's customers include some of the
     leading wireless OEMs, including Nokia, Motorola, QUALCOMM, Samsung and LG.
     The Company continuously pursues opportunities to use its RF circuit design
     and engineering capabilities and Optimum Technology Matching(R) expertise
     to provide cost-effective integrated circuit solutions for emerging high
     volume wireless applications.
 
          Offer a Wide Range of RF Products.  The Company supplies its customers
     with a broad range of standard and custom-designed RFICs in order to
     position itself as a "one-stop" solution for its customers' RFIC needs. The
     Company offers a full line of products that include power amplifiers, low
     noise amplifiers/mixers, quadrature modulators/demodulators and automatic
     gain control amplifiers. For cellular and PCS applications, the Company
     offers products addressing virtually all of the analog and digital air
     interface standards. The Company's design engineering staff has developed
     proprietary design and fabrication modeling techniques and tools to enable
     the Company to deliver state-of-the-art integrated circuit designs that
     meet its customers' stringent technical specifications.
 
          Leverage GaAs HBT Capabilities.  The Company believes that its GaAs
     HBT expertise allows it to deliver high efficiency, high performance
     components such as linear power amplifiers and low noise amplifiers to the
     wireless communications markets. As the Company improves its design and
     manufacturing of GaAs HBT components, it will seek to incorporate GaAs HBT
     technology in other RF components in an effort to improve the price
     performance characteristics of its products. Through its Optimum Technology
     Matching(R) strategy, the Company is often able to leverage GaAs HBT design
     wins into additional sales for its silicon and GaAs MESFET components.
 
          Expand Manufacturing Capacity.  In June 1996, the Company entered into
     a strategic relationship with TRW in order to provide GaAs HBT components.
     As a part of this relationship, TRW is expanding its GaAs HBT manufacturing
     capacity. In addition, the Company is constructing an approximately 50,000
     square foot fabrication facility in which the Company intends to fabricate
     its own GaAs HBT wafers using TRW's proprietary GaAs HBT and related wafer
     fabrication technologies. This facility currently is scheduled to reach
     commercial production levels in the second half of 1998. See "Risk
     Factors -- Construction and Operation of Fabrication Facility" and
     "Management's Discussion and Analysis of Financial Condition and Results of
     Operations -- Liquidity and Capital Resources." The Company believes that
     operating its own GaAs HBT wafer fabrication facility will improve its
     ability to respond to customer demand for GaAs HBT products and will
     provide it with greater opportunities to enhance product and process
     quality and reliability.
 
          Maintain Balanced Product Mix.  The Company strives to maintain a
     balance between custom and standard products. Custom-designed products are
     usually developed for volume production orders from large OEMs. Custom
     products normally are manufactured on an exclusive basis for the
     originating customer for a negotiated period of time. Once exclusivity
     periods expire, the Company attempts to migrate custom products rapidly
     into the standard product category in order to broaden its customer base
     and leverage its design and product development expenditures.
 
MARKETS
 
     The Company designs, develops and markets its products to both domestic and
international OEMs for commercial applications in the wireless markets,
including cellular and PCS handsets, cordless telephony,
 
                                       29
<PAGE>   33
 
industrial radios, WLAN equipment, WLL handsets, wireless security systems and
wireless utility meter reading systems.
 
  Cellular Telephony and Personal Communication Services
 
     In cellular and PCS applications, calls are placed through hand held
subscriber devices by establishing a connection with a base station via RF
channels. While the initial PCS services are comparable to cellular telephony,
as PCS becomes more widely deployed, it is expected that a subscriber will be
able to use a single small, lightweight handset and a single phone number for
all calls in the home, office or elsewhere with relatively seamless routing.
Based on information published by Dataquest, there were 85.5 million cellular
subscribers worldwide at the end of 1995 and this number was projected to grow
to 363.8 million by 2000.
 
  Cordless Telephony
 
     Cordless telephones are moving from first generation analog phones
operating at low (46-49 MHz) frequencies to digital cordless phones operating at
higher frequencies. In the United States, new phones operating in the 902-928
MHz frequency range use spread spectrum modulation to provide improved range and
voice quality, less interference and greater security. In Western Europe, the
Digital European Cordless Telephone, which operates in the 1880-1900 MHz
frequency range, has been successfully introduced, and, in Japan, the Personal
HandyPhone System ("PHS") was introduced in July 1995. PHS operates at the 1895-
1907 MHz frequency range and acts as a cordless telephone while at home, a
wireless PBX extension at the office, and a low mobility cellular-like phone
elsewhere.
 
  Wireless Local Loop Systems
 
     A WLL system is a fixed location wireless communications system in which
the end user is connected to the local telephone company's central switch via a
wireless connection. WLL systems employ simplified cellular or PCS technology.
The absence of high speed mobility, roaming or intercell handoff requirements
make the infrastructure and operating costs of WLL systems significantly lower
than traditional wired and cellular systems. WLL systems can be rapidly
deployed, even in difficult terrain areas, and are easily scalable.
 
  Wireless Networks
 
     Wireless networking involves the transmission and reception of data such as
e-mail, faxes and computer files by desktop and portable computers via wireless
RF links rather than wired lines. Network coverage ranges from wireless LANs,
which might be found within a business or single building, to metropolitan area
networks, which would be limited to a defined metropolitan or geographic area,
to wide area networks, which connect individuals and work groups over larger
geographic areas.
 
  Industrial Radios
 
     Industrial digital radios are trunked radio networks that transmit voice
communications from one location to another (point-to-point) and from one
location to many locations (point-to-multipoint). Industrial radios are
primarily used by law enforcement officers and in other public safety
applications.
 
  Other Markets
 
     The Company also supplies custom components for other applications in
wireless markets, such as wireless security systems and wireless utility meter
reading systems, and is pursuing other emerging wireless markets, including
enhanced two-way paging, wireless environmental monitoring devices and wireless
handheld devices used for point-of-sale, bar coding and other applications. The
Company also pursues opportunities to leverage the technological advantages of
its RF components by identifying applications in other markets. For example, the
Company has applied its RF power amplifier design expertise to develop high
performance power line amplifiers for the cable television ("CATV") market and
markets various GaAs HBT and MESFET components for satellite and microwave
communications applications. In addition, certain of its
 
                                       30
<PAGE>   34
 
components, such as gain blocks and attenuators, are used for instruments and in
other non-wireless applications.
 
TECHNOLOGY
 
     The following diagram illustrates a typical wireless system:
 
                                     CHART
 
     In the receive mode, a signal strikes the antenna and is applied to a low
noise amplifier (LNA). The LNA amplifies the strength of the incoming signal by
a factor of approximately 10 to 1,000 times and applies it to the mixer. Without
distorting the information contained, the mixer transforms the carrier frequency
of the signal from its original high value, termed an RF frequency (869-894 MHz
for cellular systems and 1930-1990 MHz for PCS systems), to a lower frequency
(usually at 200 MHz or less) called an "intermediate frequency" ("IF"). The IF
amplifier then amplifies this signal further while reducing much of its
amplitude variation before it is applied to the quadrature demodulator where the
digital information is recovered from the signal. This digital information is
supplied to the baseband portion of the handset where it is processed to recover
the original voice or data.
 
     In the transmit mode, voice or other data that the user desires to transmit
is processed into digital information in the baseband section of the handset.
This information is applied to the quadrature modulator, where the digital
information is combined with an intermediate frequency carrier signal. This
modulated IF signal is applied to the upconverter where it is raised to an RF
frequency (824-849 MHz for cellular and 1850-1910 MHz for PCS). The linear power
amplifier then amplifies this low strength signal significantly to levels of one
watt or more to allow the signal to cover substantial distances as it leaves the
antenna. The linear power amplifier must produce this high-level signal with a
minimum of distortion, particularly when processing signals employing complex
digital modulation standards such as CDMA.

Description of Graphic in Business Section

This graphic, titled "Simplified digital handset," illustrates the basic
components of the RF section of a typical wireless communications system and the
sequence in which information travelling through such a system is applied to
these components.  The bottom right corner contains the words "Baseband
Section."  Immediately above is a line formed into a rectangular wave pattern,
meant to depict the passage of digital information.  Immediately above this wave
pattern is an arrow pointing to the left, and to the pattern's left in
descending order are the letters "I" and "Q".  A line leads to the left from
each of these letters, crossing a vertical dotted line that runs the length of
the graphic and denotes the division between the baseband section, which
occupies approximately one quarter of the graphic, and the RF section, which
occupies the remainder of the graphic.  The words "RF Section" appear at the
bottom of this latter section.  Immediately above is a rectangle of dotted lines
with the word "Transmitter" at the top.  Within this rectangle are, from right
to left, a rectangle in which the words "Quadrature Modulator" appear (and the
right side of which the lines extending from the letters "I" and "Q" in the
baseband section touch), a rectangle in which the word "Upconverter" appears and
a triangle, pointing to the left, in which the words "Linear PA" appear.  These
three shapes are linked by a line that continues to the left of the triangle,
passes through the left side of the rectangle of dotted lines in which the three
shapes are located, and turns upward, where it reaches a stylized depiction of
an antenna emitting a signal that occupies the upper left corner of the graphic.
The word "Antenna" appears immediately below this depiction. The line continues
upward and then turns to the right, where it crosses into another rectangle of
dotted lines.  This rectangle has the word "Receiver" immediately above it and
contains three rectangles that are linked by the line and contain the labels,
from left to right, "LNA/Mixer," "Gain Control IF Amplifier" and "Quadrature
Demodulator."  From the right side of the rightmost rectangle, two parallel
lines extend rightward through the right side of the rectangle of dotted lines
in which these three shapes are located and across the vertical dotted line
representing the division between the RF section and the baseband section.
Within the baseband section, the two parallel lines reach another pair of the
letters "I" and "Q," which are in descending order.  To the right of these
letters appears another line formed into a rectangular wave pattern, meant to
depict the passage of digital information.  Immediately above this pattern, in
the upper right corner of the graphic, is an arrow pointing to the right.

  Power Amplifiers
 
     Power amplifiers provide signal amplification in the transmitter section of
a wireless system in order to boost a signal through the antenna. Power
amplifiers operate at different frequencies, power levels and air interface
standards and generally are classified either as linear amplifiers, which add a
minimum amount of distortion to the shape of the input signal, or non-linear
amplifiers, which are used in analog devices. Power amplifiers are often the
most critical RF component for a number of reasons. They frequently are the most
expensive component and are difficult to design and implement. In addition,
power amplifiers normally use the greatest amount of battery power in a handset,
which impacts talk time, and they generally dissipate the greatest amount of
heat. The Company's GaAs HBT power amplifiers offer low distortion, small size,
high efficiency and improved linearity, and they are able to operate from a
single polarity power source.

  Quadrature Modulators/Demodulators
 
     Quadrature modulators are devices in the transmitter section of a wireless
system that combine digital information with an RF signal by varying the phase
and amplitude of the signal so that the resulting signal can be transmitted.
Quadrature demodulators reverse this process in the receiver section by taking
received RF signals and recovering the embedded digital information for further
processing. The Company believes its GaAs HBT process technology produces
quadrature modulators/demodulators with superior amplitude and phase balance.
 
  Low Noise Amplifiers/Mixers
 
     A low noise amplifier (LNA) is a device in the receiver section of a
wireless system that receives signals from an antenna at extremely low microvolt
levels and amplifies such signals by a factor of approximately 10 to 1,000 times
with the addition of as little "white noise" as possible. In general, the less
noise added by a LNA, the weaker the signal it can process. LNAs are commonly
integrated into circuits with mixers (also referred to as "down-mixers" or "down
converters"), and this combination generally is referred to as a "receiver front
end." Mixers accept the filtered output from the LNA, which is typically at a
high frequency and difficult to process, and mix it with a local oscillator
signal to produce a lower frequency (IF) signal, which is easier to process.
 
  IF Components
 
     In a typical handset, high frequency RF signals are converted into lower
frequency IF signals by the LNA/Mixer and then to baseband in the receive
functions. In the transmit function, baseband inputs (e.g., voice) are converted
from analog to digital form and processed through the IF range to the higher RF
frequency before transmission through the antenna. RFMD's IF devices include
digitally controlled IF amplifiers, which amplify baseband signals after they
have been converted from analog to digital form, and IF amplifiers with
automatic gain control and received signal strength indicators, which are used
for IF-to-baseband conversion in the receive mode.
 
  Gain Blocks
 
     Gain blocks are simple general purpose amplifiers that boost signals over a
broad frequency range. They are used for amplifier applications whenever noise
is not a concern and whenever a signal's strength has been diminished by
processing through a filter or other component.
 
  Transceivers
 
     Transceivers are highly integrated circuits that combine transmitters with
receivers into a single device. Because this degree of integration generally
results in some performance compromises, single chip transceivers tend to be
used in cost-sensitive applications where performance is less critical.
 
  Attenuators
 
     An attenuator is a device that reduces the level of an input signal by
controllable amounts. RFMD's attenuators are programmable through use of an
external analog or digital control signal to reduce signals to desired levels
with minimal noise and signal loss when the device is not active. Like gain
blocks, attenuators have many applications both within and outside the wireless
markets.

     For the year ended March 31, 1997, sales to QUALCOMM and Samsung were
approximately $9.3 million and $6.7 million, respectively, representing
approximately 32.1% and 23.4%, respectively, of the Company's revenues. Because
of the Company's inability to meet delivery terms and quantity requirements,
QUALCOMM has determined to produce internally certain components and to look to
other sources for other components to replace all products currently purchased
from the Company. Accordingly, the Company expects that sales to QUALCOMM will
cease in May 1997. See "Risk Factors -- Variability of Operating Results;
Dependence on a Limited Number of Customers; GaAs HBT Capacity Constraints." The
Company expects to be a leading supplier of GaAs HBT RFICs based on sales after
giving effect to the expected loss of sales to QUALCOMM. For information with
respect to export sales by geographic area, see Note 2 of Notes to Financial
Statements.
    
 
     The Company, TRW and Nokia have agreed in principle to cooperate to develop
and supply Nokia with RFICs that are manufactured using TRW's GaAs HBT
processes. The arrangement contemplates that the Company and Nokia will
negotiate separate agreements to address the development and supply of each
component. Pursuant to the arrangement, the Company has agreed to provide Nokia
with access to certain RFIC technologies and to its GaAs HBT foundry if and when
such facility becomes operational, and Nokia has agreed to provide the Company
with rights to bid for and supply Nokia's requirements for certain RFICs. The
arrangement can be terminated without penalty by TRW, the Company or Nokia for
any reason. The
 
                                       34
<PAGE>   39
 
arrangement does not obligate Nokia to purchase any products from the Company,
and there can be no assurance that Nokia will become or subsequently remain a
significant customer of the Company or that this relationship will continue. See
"Risk Factors -- Relationship with Nokia."
 
SALES AND MARKETING
 
     The Company sells its products worldwide directly to customers as well as
through a network of 27 domestic sales representative firms and 26 foreign sales
representative firms. The Company selects its domestic and foreign
representatives based on technical skills and sales experience, as well as the
presence of complementary product lines and the customer base served. The
Company provides ongoing training to its representatives to keep them
knowledgeable of the Company's products. The Company maintains an internal
marketing organization that is responsible for developing sales and advertising
literature, such as product announcements, catalogs, brochures and magazine
articles in trade and other publications, and preparing technical presentations
for industry conferences.
 
     The Company believes that maintaining a close relationship with customers
and providing customers with ongoing technical support is essential to customer
satisfaction in the wireless communications industry. The Company's design and
application staff interacts with customers during all stages of design and
production, provides customers with current product application notes and
engineering data, maintains regular contact with customer engineers and assists
in the resolution of technical problems. The Company assigns to its largest
customers a contract account manager who maintains regular contact with the
customer to determine its product needs and concerns. Members of senior
management also are involved in managing relationships with significant
customers. The Company believes that maintaining close contact with customers
improves their level of satisfaction and enables the Company to anticipate their
future product needs.
 
MANUFACTURING, PACKAGING AND TESTING
 
     The Company's manufacturing cycle consists of semiconductor wafer
fabrication, assembly and packaging and final product testing. With the
exception of product testing, the Company outsources all stages of production.
The Company uses independent foundries located in the United States to
manufacture its products. The Company uses two independent foundries to supply
its silicon-based product requirements and two independent foundries to supply
its GaAs MESFET devices. The Company purchases all GaAs HBT wafers from TRW. See
"-- Strategic Relationship with TRW." Although TRW is in the process of
expanding its fabrication facility to increase its capacity to fabricate GaAs
HBT wafers, the Company has experienced capacity limitations on its ability to
supply GaAs HBT components. To address these concerns, the Company is seeking to
establish an additional source for such products and is constructing a
fabrication facility at which it plans to fabricate such products. The Company's
reliance on independent foundries involves a number of risks, including the
possibility of material disruptions in the supply of key RFICs and the lack of
control over delivery schedules, manufacturing yields, quality and fabrication
costs. See "Risk Factors -- Dependence on TRW" and "-- Dependence on Third
Parties."
 
     The Company intends to use a portion of the net proceeds from this offering
to construct an approximately 50,000 square foot fabrication facility adjacent
to its existing facility in Greensboro, North Carolina to fabricate four-inch
GaAs HBT wafers using technologies licensed from TRW. The facility will be
constructed in two phases, the first of which is budgeted at approximately $40
million and involves construction of the building shell, installation and
certification of an approximately 10,300 square foot clean room and the purchase
or lease and installation of the required fabrication equipment. The first phase
will continue until the GaAs HBT process technology transfer from TRW is
completed and specified commercial production yields are attained, which is
anticipated to occur in the second half of 1998. The second phase is budgeted at
approximately $30 million and involves an approximately 6,000 square foot
expansion to the clean room and the purchase or lease and installation of an
additional production equipment. The commencement and completion of the second
phase of the fabrication facility are dependent on a number of factors,
including the timing of completion of the first construction phase, the
availability of necessary capital, whether the Company successfully completes
the transfer of TRW's GaAs HBT and MBE processes, the demand for GaAs HBT
products and a number of other factors both within and outside the control of
the Company. See
 
                                       35

"Risk Factors -- Construction and Operation of Fabrication Facility,"
"-- Adoption of GaAs HBT Components," "-- Need for Additional Capital" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
 
     The Company maintains an inventory of certain standard products based on
its internal forecasts of expected demand for such products. For custom-designed
products, designs of the Company's products are verified by both the Company and
the customer before orders for production wafers are placed. Upon receipt of
orders from an OEM, the Company schedules production based on order size,
customer delivery requirements, production schedules and other production
considerations. The Company's GaAs HBT products are subject to supply
constraints as discussed under "Risk Factors -- Variability of Operating
Results; Dependence on a Limited Number of Customers; GaAs HBT Capacity
Constraints" and "-- Dependence on TRW."
 
   
     The Company currently uses five vendors located in Asia and one vendor
located in the United States to package and assemble its products. All of such
vendors are certified to applicable ISO 9000 series specifications, which means
that their operations have in each case been determined by independent examiners
to comply with certain internationally developed quality control standards. The
Company qualifies and monitors assembly contractors based on cost and quality.
Such contractors typically provide the Company with per-unit pricing. The
Company has encountered packaging quality problems with certain of such vendors,
particularly with regard to GaAs products which generally are more brittle than
silicon-based products and therefore more susceptible to breakage. The Company
believes that until it can obtain and train additional vendors to package its
GaAs products, it will have to continue to monitor closely its vendors as
production volumes increase. See "Risk Factors -- Dependence on Third Parties"
and "-- International Sales and Operations."
    
 
     The Company tests 100% of its products for compliance with both DC and RF
parameters at its facility in Greensboro, North Carolina.
 
STRATEGIC RELATIONSHIP WITH TRW
 
     In June 1996, the Company and TRW entered into a broad strategic
relationship based on several agreements which evidence an investment by TRW in
RFMD, a technology license from TRW to the Company (the "License Agreement") and
a supply arrangement between the parties (the "Supply Agreement"). As a part of
such alliance, TRW provided the Company with $15 million of equity and debt
financing and became a significant shareholder in the Company. See "Principal
and Selling Shareholders" and "Certain Transactions -- TRW." The key goal of the
Company in entering into this alliance was to enable the Company to construct a
four-inch wafer fabrication facility to manufacture products using GaAs HBT
technologies developed by TRW and licensed to the Company.
 
     Pursuant to the License Agreement, TRW has granted to the Company fully
paid up, royalty-free, worldwide licenses with respect to certain of TRW's
existing and future GaAs HBT patent rights and MBE process patent rights, in
each case with accompanying know-how and technical information, to design,
develop, manufacture, market, service and repair certain existing products of
the Company and any GaAs HBT product in which the emitter of the GaAs HBT has a
width of one to three microns, in either case provided such products are for
commercial wireless communications applications and operate on signals having a
frequency of less than 10 GHz. The license with respect to the GaAs HBT rights
currently is effective, and the MBE license becomes effective as of the date
that the Company's wafer fabrication facility becomes operational. Subject to
TRW's right to use the licensed technology to fulfill existing contractual
obligations and to provide to customers on an ongoing basis certain specified
foundry services, both licenses are exclusive as to all persons including TRW,
but may be made non-exclusive at the option of TRW if the Company fails to meet
certain revenue goals. See "Risk Factors -- Dependence on TRW" and "Certain
Transactions -- TRW -- License Agreement."
 
     TRW also granted non-exclusive licenses to the Company to use certain of
its existing GaAs HBT rights and MBE rights for the development and sale of
certain of the Company's existing products for applications other than
commercial wireless communications or that operate on signals having a frequency
of 10 GHz or
 
                                       36
<PAGE>   41
 
more. In addition, TRW agreed to provide certain technical assistance to the
Company in connection with the design, construction and operation of the
Company's planned wafer fabrication facility. The License Agreement provides
that TRW will offer to the Company, on the same terms as are offered to third
parties, certain future non-HBT related technologies that it develops for a
period of 10 years following the date on which the Company's wafer fabrication
facility becomes operational. The Company has agreed to share with TRW any
modifications or improvements that it makes in the technology or the products
developed therefrom, and to grant TRW a non-exclusive, royalty-free license to
use such modifications or improvements in applications outside the Company's
field of use. The licenses granted pursuant to the License Agreement are granted
without representation or warranty as to validity or noninfringement and may be
terminated by TRW if the Company's wafer fabrication facility is not operational
by December 31, 1998. In addition, upon any termination of the License Agreement
for default, whether due to the default of the Company or otherwise, the
Company's rights to TRW's technologies shall cease. See "Risk
Factors -- Dependence on TRW" and "Certain Transactions -- TRW -- License
Agreement."
 
     Under the terms of the Supply Agreement, the Company has agreed to purchase
from TRW, and TRW has agreed to sell to the Company, certain minimum quantities
of three-inch GaAs HBT processed wafers and four-inch GaAs epitaxial wafer
starting material until December 31, 2000, which quantities decline
significantly from current levels beginning in 1999. The Company currently is
purchasing from TRW a number of wafers that approximates the minimum number of
wafers required to be delivered by TRW to the Company under the Supply
Agreement. However, the Company believes that in future periods it may purchase
from TRW a quantity of wafers in excess of the minimum quantity of wafers
required to be supplied by TRW under such contract. See "Risk
Factors -- Dependence on TRW" and "Certain Transactions -- TRW -- Supply
Agreement."
 
RESEARCH AND DEVELOPMENT
 
   
     The Company's research and development efforts are focused primarily on the
development of new integrated circuit products. At March 31, 1997, there were 44
persons in the Company's research and development organization. The Company's
research and development efforts also are directed at improving manufacturing
processes and yields. In fiscal 1995, 1996 and 1997, the Company incurred
approximately $2.8 million, $4.2 million and $6.2 million, respectively, of
research and development expenses. The Company does not separately account for
Company-sponsored and customer-sponsored research and development expenses.
    
 
     The market for RFICs is characterized by rapid changes in product designs
and the emergence of new semiconductor technologies used to fabricate higher
performance devices. Because the demand of OEMs for continual improvements in
product performance is expected to increase, the Company believes that its
future success depends in part on its ability to design RFICs under emerging
wafer fabrication technologies that meet the cost and performance parameters of
its customers. See "Risk Factors -- Rapid Technological Change; Dependence on
Development and Growth of Wireless Markets."
 
COMPETITION
 
     Competition in the markets for the Company's products is intense. The
Company faces competition from several companies primarily engaged in the
business of designing, manufacturing and selling silicon and GaAs MESFET RFICs,
as well as suppliers of discrete products such as transistors, capacitors and
resistors. The Company may face future competition from companies that have or
may develop GaAs HBT or other fabrication processes. In addition, the Company's
current and potential competitors include OEMs that have or may develop the
ability to produce RFICs or discrete products internally for their requirements.
The Company's primary competitors include ANADIGICS, Motorola, NEC, Philips,
Rockwell and TriQuint.
 
     The Company believes that competition within the markets for its products
is driven primarily by the ability to design and deliver high performance and
price competitive products in sufficient quantities and in a timely manner.
Competition is also affected by the quality of customer service and technical
support and the
 
                                       37
<PAGE>   42
 
ability to design customized products that address each customer's particular
requirements and cost limitations.
 
     Many of the Company's current and potential competitors have entrenched
market positions, established patents, copyrights, trade names, trademarks and
intellectual property rights and substantial technological capabilities.
Further, most of the Company's current and potential competitors have
significantly greater financial, technical, manufacturing and marketing
resources than the Company. Increased competition could adversely affect the
Company's revenue and profitability by causing it to reduce prices or by
reducing demand for the Company's products. See "Risk Factors -- Competition."
 
INTELLECTUAL PROPERTY
 
     It is the Company's practice to seek U.S. patent and copyright protection
on its products and developments, where appropriate, and to protect its
proprietary technology under U.S. and foreign laws affording protection for
trade secrets and for integrated circuit designs. The Company owns one U.S.
patent and has one pending U.S. patent application. The U.S. patent was issued
on March 4, 1997 and will expire in 2015.
 
     The Company relies primarily upon trade secrets, technical know-how and
other unpatented proprietary information relating to its product development and
manufacturing activities. To protect its trade secrets, technical know-how and
other proprietary information, the Company's employees are required to enter
into agreements providing for maintenance of confidentiality and the assignment
of rights to inventions made by them while in the employ of the Company. The
Company also has entered into non-disclosure agreements to protect its
confidential information delivered to third parties in conjunction with possible
corporate collaborations and for other purposes. However, there can be no
assurance that these types of agreements will effectively prevent unauthorized
disclosure of the Company's confidential information, that these agreements will
not be breached, that the Company would have adequate remedies for any breach or
that the Company's trade secrets and proprietary know-how will not otherwise
become known or independently discovered by others. See "Risk
Factors -- Intellectual Property Claims."
 
   
     While the Company has not been involved in any patent or other intellectual
property rights litigation, there can be no assurance that third parties will
not assert claims against the Company with respect to existing and future
products. In the event of litigation to determine the validity of any third
party's claims, such litigation could result in significant expense to the
Company, and divert the efforts of the Company's technical and management
personnel, whether or not such litigation is determined in favor of the Company.
The wireless industry is subject to frequent litigation regarding patent and
other intellectual property rights. Leading companies and organizations in the
wireless industry have numerous patents that protect their intellectual property
rights in these areas. In the event of an adverse result of any such litigation,
the Company could be required to expend significant resources to develop
non-infringing technology or to obtain licenses to the technology which is the
subject of the litigation. There can be no assurance that the Company would be
successful in such development or that any such license would be available on
commercially reasonable terms.
    
 
BACKLOG
 
   
     At March 31, 1997, the Company's backlog was approximately $19.2 million.
At March 31, 1996, the Company's backlog was approximately $15.0 million.
Purchase orders from QUALCOMM represented approximately $1.5 million and $3.8
million of the Company's backlog at March 31, 1997 and March 31, 1996,
respectively. The Company includes in its backlog all accepted product purchase
orders for which delivery has been specified within one year. Product orders in
the Company's backlog are subject to changes in delivery schedules or to
cancellation at the option of the purchaser without significant penalty. The
Company's backlog may vary significantly from time to time depending upon the
level of capacity available to satisfy unfilled orders. Accordingly, although
useful for scheduling production, backlog as of any particular date may not be a
reliable indicator of sales for any future period.
    
 
                                       38
<PAGE>   43
 
EMPLOYEES
 
   
     At March 31, 1997, the Company had 131 full-time employees. The Company
believes that its future prospects will depend, in part, on its ability to
continue to attract and retain skilled technical, marketing and management
personnel. Competition for such personnel is intense, and the number of persons
with relevant experience, particularly in engineering, software design and
marketing, is limited. None of the Company's employees is represented by a labor
union, and the Company has never experienced any work stoppage. The Company
believes that its employee relations are good. See "Risk Factors -- Management
of Growth" and "-- Dependence Upon Key Personnel."
    
 
FACILITIES
 
     The Company's principal administrative facility is located in a building
comprising approximately 25,000 square feet in Greensboro, North Carolina. The
Company leases such building under a lease agreement that expires at the end of
2002, the term of which may be extended for an additional three years. The
Company has the option to request an expansion of this facility, in which case
the term of the lease would be extended to seven years from the date of
completion of such expansion. The Company has leased real estate adjacent to its
principal facility for the construction by a third party real estate developer
of a wafer fabrication facility that will consist of approximately 50,000 square
feet initially. The Company intends to use a portion of the net proceeds from
this offering to finance a portion of the cost of constructing the first phase
of this facility. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources." The
lease for the fabrication facility has a term of 15 years from the date of
completion of the initial stage, which is anticipated to occur in the second
half of 1998, with two 10-year renewal options. The Company also leases
approximately 17,500 square feet of commercial space in Greensboro, North
Carolina that it uses for office space and storage. Such facility is leased
under three leases that each expire at the end of 1999.
 
LEGAL AND ENVIRONMENTAL MATTERS
 
     The Company is not a party to any legal proceeding.
 
     If, and at such time as, the Company's planned wafer fabrication facility
becomes operational, the Company will be subject to a variety of extensive and
changing federal, state and local governmental laws, regulations and ordinances
related to the use, storage, discharge and disposal of toxic, volatile or
otherwise hazardous chemicals used in the RFIC manufacturing process. Any
failure to comply with such requirements then in effect or subsequently adopted
could result in the imposition of fines on the Company, the suspension of
production or a cessation of operations. In addition, such requirements could
restrict the Company's ability to expand its facilities or require the Company
to acquire costly equipment or incur other significant expenses to comply with
environmental regulations or clean up discharges. The Company believes that
costs arising from existing environmental laws will not have a material adverse
effect on the Company's financial position or results of operations. There can
be no assurance, however, that the environmental laws will not become more
stringent in the future or that the Company will not incur significant costs in
the future in order to comply with such laws.

(1) The potential realizable value is calculated based on the term of the option
     at its time of grant (10 years) and is calculated by assuming that the
     stock price on the date of grant as determined by the Board of Directors
     appreciates at the indicated annual rate compounded annually for the entire
     term of the option and that the option is exercised and sold on the last
     day of its term for the appreciated price. The 5% and 10% assumed rates of
     appreciation are derived from the rules of the Securities and Exchange
     Commission (the "Commission") and do not represent the Company's estimate
     or projection of the future Common Stock price.
 
   
(2) Such options vest and become exercisable in five equal installments on the
     first five anniversaries of the date of grant.
    
 
   
STOCK OPTION PLANS
    
 
  1992 Stock Option Plan
 
     The Company's 1992 Stock Option Plan (the "1992 Option Plan") was adopted
by the shareholders of the Company in February 1992. The 1992 Option Plan
provides for the grant of options to purchase Common Stock to key employees,
non-employee directors and advisors and consultants in the service of the
Company. The 1992 Option Plan permits the granting of both incentive stock
options (options that meet the requirements of Section 422A of the Internal
Revenue Code of 1986, as amended (the "Code")) ("Incentive Options") and
nonqualified stock options (options that do not meet such requirements)
("Nonqualified Options"). The aggregate number of shares of Common Stock that
may be issued pursuant to options granted under the 1992 Option Plan may not
exceed 1,426,000 shares, subject to adjustment upon the occurrence of certain
events affecting the Company's capitalization.
 
     The 1992 Option Plan is administered by the Compensation Committee of the
Board of Directors (see "-- Board Committees" and "-- Compensation Committee
Interlocks and Insider Participation"), which is authorized, subject to the
provisions of the 1992 Option Plan, to determine to whom and at what time
options may be granted, the designation of each option as either an Incentive
Option or a Nonqualified Option, the per
 
                                       44
<PAGE>   49
 
share exercise price, the duration of each option, the number of shares subject
to each option, the rate and manner of exercise and the timing and form of
payment.
 
     An Incentive Option may not have an exercise price less than the fair
market value of the Common Stock on the date of the grant or an exercise period
that exceeds ten years from the date of grant, may not be granted to any person
who holds more than 10% of the total combined voting power of all classes of
capital stock of the Company (unless the terms of such Incentive Option meet
certain additional criteria) and is subject to certain other limitations that
allow the optionee to qualify for favorable tax treatment. Nonqualified Options
may have an exercise price less than the fair market value of the underlying
Common Stock on the date of grant and may have an exercise period of more than
ten years from the date of grant. Other than as described below, no option
granted under the 1992 Option Plan may be exercisable during the six months
immediately following the date of grant.
 
   
     Except as may be provided in an individual option agreement, if the
employment or service of a person to whom an option has been granted under the
1992 Option Plan is terminated for any reason, the optionee or his or her
personal representative may exercise such option to the extent that he or she
was entitled to exercise it as of the date of termination only during the 30-day
period following such termination and in no event after the expiration of ten
years from the date such option was granted. No option granted under the 1992
Option Plan may be transferred by the optionee. Shares issued upon the exercise
of options granted under the 1992 Option Plan are subject to repurchase by the
Company at fair market value, at the Company's option, upon the death,
disability or other termination of the optionholder's employment with the
Company.
    
 
     The 1992 Option Plan includes provisions designed to protect the rights of
optionholders upon the occurrence of certain events affecting the capital stock
of the Company, and provides for the acceleration of the exercisability of all
options granted thereunder in the event of the acquisition or a sale of
substantially all the assets of the Company or a business combination in which
the Company's shareholders would receive less than 50% of the resulting
corporation's voting capital stock.
 
   
     As of March 31, 1997, the Company had granted options to employees
(including certain officers; see "-- Option Grants During Fiscal 1996" and
"Principal and Selling Shareholders") for 1,065,116 shares of Common Stock under
the 1992 Option Plan, of which options for 18,080 shares have been exercised and
options for 15,700 shares have been forfeited. The exercise prices of
outstanding options granted under the 1992 Option Plan range from $0.15 to $9.00
per share, with a weighted average of $2.09 per share. The Company intends to
terminate the 1992 Option Plan effective upon the consummation of this offering,
after which no additional options will be awarded under the 1992 Option Plan.
Such action will not affect options outstanding under the 1992 Option Plan.
    
 
  1997 Key Employees' Stock Option Plan
 
     The Company has adopted the 1997 Key Employees' Stock Option Plan (the
"1997 Option Plan"), which provides for the grant of options to purchase Common
Stock to key employees and independent contractors in the service of the
Company. The 1997 Option Plan permits the granting of both Incentive Options and
Nonqualified Options. The aggregate number of shares of Common Stock that may be
issued pursuant to options granted under the 1997 Option Plan may not exceed
1,300,000 shares, subject to adjustment in the event of certain events affecting
the Company's capitalization.
 
     The 1997 Option Plan is administered by the Compensation Committee of the
Board of Directors (see "-- Board Committees"), which is authorized, subject to
the provisions of the 1997 Option Plan, to determine to whom and at what time
options may be granted, the designation of the option as either an Incentive
Option or a Nonqualified Option, the per share exercise price, the duration of
each option, the number of shares subject to each option, the rate and manner of
exercise and the timing and form of payment.
 
     An Incentive Option may not have an exercise price less than the fair
market value of the Common Stock on the date of the grant or an exercise period
that exceeds 10 years from the date of grant, and is subject to certain other
limitations that allow the optionee to qualify for favorable tax treatment.
Nonqualified Options
 
                                       45
<PAGE>   50
 
may have an exercise price less than the fair market value of the underlying
Common Stock on the date of grant but, like Incentive Options, are limited to an
exercise period of no longer than 10 years.
 
     Except to the extent, if any, as may be permitted by the Code, Rule 16b-3
under the Securities Exchange Act of 1934, as amended (the "Exchange Act") or
any successor statute or rule, an option granted under the 1997 Option Plan will
not be transferable (including by pledge or hypothecation) other than by will or
the laws of intestate succession, and such an option will be exercisable during
the optionee's lifetime only by the optionee. If an optionee is subject to
Section 16 of the Exchange Act, shares acquired upon the exercise of an option
will not, without the consent of the Compensation Committee, be transferable
(including by pledge or hypothecation) until the expiration of six months after
the date the option was granted. In addition, the Company may impose such
restrictions on any shares acquired upon exercise of options granted under the
1997 Option Plan as it may deem advisable, including, without limitation,
transfer and other restrictions necessary to ensure compliance with the
Securities Act and any blue sky or securities laws applicable to such shares.
 
     As a general matter, no option granted under the 1997 Option Plan to an
optionee who was an employee of the Company or a related corporation at the time
of the grant may be exercised unless the optionee is, at the time of exercise,
an employee of the Company or any of its subsidiaries and has been an employee
continuously since the date the option was granted, subject to certain
post-termination provisions in the case of Incentive Options.
 
  Directors' Option Plan
 
     The Company has adopted the Directors' Option Plan, the purpose of which is
to compensate nonemployee directors for their service on the Board of Directors,
enable such directors to increase their holdings of Common Stock and allow the
Company to attract and retain qualified nonmanagement directors. Under the
Directors' Option Plan, directors who are not employees of the Company are
entitled to receive options to acquire shares of Common Stock in accordance with
the terms of the plan. An aggregate of 200,000 shares of Common Stock have been
reserved for issuance under the Directors' Option Plan, subject to adjustment
for certain events affecting the Company's capitalization. There currently are
five directors of the Company eligible to participate in the Directors' Option
Plan.
 
     The Directors' Option Plan is administered by the Compensation Committee of
the Board of Directors. Subject to the provisions of the plan, the Compensation
Committee has full and final authority, in its discretion, to establish, amend
and rescind rules and regulations for the administration of the plan, to
construe and interpret the plan, the rules and regulations for the plan and the
agreements evidencing options and to make all other determinations deemed
necessary or advisable for administering the plan. However, no director or any
other person has any discretion with respect to the granting of options pursuant
to the plan.
 
     Under the Directors' Option Plan, each director who is not an employee of
the Company will be entitled to receive an initial award in the form of an
option to purchase 10,000 shares of Common Stock of the Company at the time of
consummation of this offering. Such option may be exercised upon consummation of
this offering at the initial public offering price and will expire to the extent
not exercised prior to the tenth anniversary of the date on which this offering
is consummated. In addition, each nonemployee director of the Company who is
first elected to the Board of Directors after consummation of this offering will
be granted an initial award (an "Initial Award") on the date of such election of
options to purchase 10,000 shares of Common Stock of the Company. Further, each
nonemployee director of the Company will be granted an award (an "Annual Award")
to purchase 5,000 shares of Common Stock of the Company on each anniversary of
his or her initial grant so long as he or she remains a member of the Board of
Directors.
 
     Initial Awards and Annual Awards will be exercisable on a per share basis
at the fair market value per share of the Common Stock on the date of grant. For
purposes of the Directors' Option Plan, "fair market value" means the closing
sale price of the Common Stock as reported on the Nasdaq National Market on the
date of grant.
 
                                       46
<PAGE>   51
 
     Initial Awards and Annual Awards will vest in equal annual installments
over the three-year period following the date of grant and will expire on the
tenth anniversary of the date of grant. Except as described below, no options
covered by Initial Awards and Annual Awards may be exercised unless the optionee
is, on the date of exercise, a director and has been a director continuously
since the date of grant.
 
     Options granted under the Directors' Option Plan will be nonqualified stock
options subject to federal income taxation under Section 83 of the Code. In
general, under Section 83 of the Code, an optionee will not be subject to
federal income tax upon the grant of an option. The exercise of an option,
however, will result in tax consequences to the optionee and to the Company.
 
  Employee Stock Purchase Plan
 
     The Company has adopted the Employee Stock Purchase Plan (the "Stock
Purchase Plan"), which is intended to qualify as an "employee stock purchase
plan" under Section 423 of the Code. All regular full-time employees of the
Company (including officers) and all other employees whose customary employment
is for more than a specified number of months in any calendar year or more than
a specified number of hours per week, who in either case have been employed by
the Company on the commencement date of the first purchase period under the
Stock Purchase Plan or for at least three months, may participate in the Stock
Purchase Plan. Directors who are not employees will not be eligible. An
aggregate of 500,000 shares of Common Stock have been reserved for offering
under the Stock Purchase Plan and are available for purchase thereunder, subject
to anti-dilution adjustments in the event of certain changes in the capital
structure of the Company.
 
     To participate in the Stock Purchase Plan, an employee must authorize the
Company in writing to deduct an amount (not less than 1% nor more than 15% of a
participant's base compensation) from his or her pay during six-month periods to
be specified in the Stock Purchase Plan (each a "Purchase Period"). On the first
day of each Purchase Period, the Company will grant to each participating
employee an option to purchase up to a specified number of shares of Common
Stock. The exercise price for the option for each Purchase Period will be the
lesser of 85% of the fair market value of the Common Stock on the first or last
business day of the Purchase Period. The fair market value will be the closing
price of the Common Stock as quoted on the Nasdaq National Market. If an
employee is not a participant on the last day of the Purchase Period, such
employee will not be entitled to exercise his or her option, and the amount of
his or her accumulated payroll deduction will be refunded to the employee. An
employee's rights under the Stock Purchase Plan will terminate upon his or her
voluntary withdrawal from the plan at any time or upon termination of
employment.
 
     The Company makes no cash contributions to the Stock Purchase Plan, but
bears the expenses of its administration. The Stock Purchase Plan is
administered by the Compensation Committee, which has authority to establish the
number and duration of the Purchase Periods during the term of the Stock
Purchase Plan, and to make rulings and interpretations thereunder.

TRW
 
     On June 6, 1996, the Company initiated a strategic alliance with TRW and
entered into agreements pursuant to which the Company issued to TRW (i) 826,446
shares of Class C Preferred Stock in exchange for $5,000,000 in cash (which
shares will convert on a one-for-one basis into Common Stock upon the closing of
this offering); (ii) 2,683,930 shares of Common Stock in exchange for TRW's
execution and performance of
 
                                       48
<PAGE>   53
 
the License Agreement, all of which shares are subject to certain voting and
transfer restrictions as described below; (iii) the TRW Convertible Note in the
maximum principal amount of $10,000,000, convertible into up to 1,111,111 shares
of Common Stock; and (iv) the TRW Warrant for the purchase, under certain
circumstances, of up to 1,000,000 shares of Common Stock at $10.00 per share.
The Company also entered into the Supply Agreement, which provides for the
purchase by the Company from TRW of certain minimum quantities of GaAs HBT
wafers and GaAs epitaxial wafers during the years 1996 to 2000, and TRW has
agreed to refrain from taking certain actions regarding control of the Company
during the five years following this offering. See "Risk Factors -- Dependence
on TRW" and "Business -- Strategic Relationship with TRW."
 
  License Agreement
 
     Pursuant to the License Agreement, TRW granted to the Company fully paid
up, royalty-free worldwide licenses with respect to certain of TRW's existing
and future GaAs HBT patent rights and MBE process patent rights, in each case
with accompanying know-how and technical information, to design, develop,
manufacture, market, service and repair certain existing products of the Company
and any product with an emitter with a width of one to three microns, in either
case provided such products are for commercial wireless communication
applications and operate on signals having a frequency of less than 10 GHz. The
license with respect to the GaAs HBT patent rights was effective immediately,
and the MBE patent right license becomes effective as of the date that the
Company's GaAs HBT wafer fabrication facility becomes operational. Both licenses
are exclusive as to all persons including TRW, except that TRW has reserved the
right to fulfill existing contractual obligations and to provide to customers on
an ongoing basis certain specified foundry services. At the option of TRW, the
license will become non-exclusive if the Company fails to meet the following
revenue goals, as measured in accordance with GAAP, following the date on which
the Company's GaAs HBT wafer fabrication facility becomes operational: during
the first year, $30 million; during the second year, $65 million; and during the
third year, $125 million. See "Risk Factors -- Dependence on TRW."
 
     TRW also granted certain non-exclusive licenses to the Company and agreed
to provide certain technical assistance to the Company in connection with the
design, construction and operation of the Company's GaAs HBT wafer fabrication
facility. The License Agreement provides that TRW will offer to the Company, on
the same terms as are offered to third parties, certain non-GaAs HBT process
technologies that it develops in the future for a period of ten years following
the date on which the Company's GaAs HBT wafer fabrication facility becomes
operational. The Company has agreed to share with TRW any modifications or
improvements and to grant TRW a non-exclusive, royalty-free license to use such
modifications or improvements outside the Company's field of use.
 
     The licenses granted pursuant to the License Agreement may be terminated by
TRW if the Company's wafer fabrication facility is not operational by December
31, 1998, unless the parties agree upon a later date. See "Risk
Factors -- Dependence on TRW."
 
  Restricted Stock Agreement
 
     The Company and TRW have entered into a restricted stock agreement with
respect to the 2,683,930 shares of Common Stock issued to TRW in consideration
of the License Agreement. Pursuant to this agreement, TRW has granted to David
A. Norbury, the President of the Company, or any successor President, an
irrevocable proxy to vote these shares in favor of any measure approved by the
Board of Directors of the Company. Any attempt by TRW to revoke this proxy would
result in all of the shares becoming redeemable, at the option of the Company,
for an aggregate purchase price of $1.00. The agreement also provides that the
shares may not be transferred by TRW to any third party without the Company's
written consent, and that any attempt at such a transfer would result in the
shares becoming redeemable as described above. Such a right of redemption will
also arise with respect to half of the 2,683,930 shares subject to the agreement
if the circumstances that would permit termination of the License Agreement
exist, namely if the Company's wafer fabrication facility is not operational by
December 31, 1998, unless the parties agree upon a later date. The agreement
does not affect TRW's right to receive any cash dividends that may be declared
and payable with
 
                                       49
<PAGE>   54
 
respect to the Common Stock. The agreement will terminate 30 days following the
agreed-upon date by which the facility must have become operational.
 
  TRW Convertible Note
 
   
     Under the terms of the TRW Convertible Note, the Company has borrowed $10
million from TRW. Unless otherwise agreed to in writing by TRW, such funds must
be used exclusively for the planning and construction and the operational,
working capital and related requirements of the Company's wafer fabrication
facility. The unpaid principal amount under the TRW Convertible Note bears
simple interest at the rate of 6% per annum and, subject to the prior conversion
of the TRW Convertible Note, all principal and accrued interest thereon is
payable in full in a lump sum on June 6, 2003. The indebtedness evidenced by the
TRW Convertible Note is subordinated to certain other indebtedness of the
Company. The Company may at its option prepay amounts owed under the TRW
Convertible Note without premium or penalty, unless TRW has initiated the
conversion of the TRW Convertible Note as described in the following paragraph.
Under the terms of the TRW Convertible Note, the Company is prohibited from
authorizing, declaring or paying any dividends until the Company's wafer
fabrication facility becomes operational. The Company is also prohibited from
incurring debt in excess of $25 million, other than debt incurred for the
construction and operation of the wafer fabrication facility.
    
 
   
     The TRW Convertible Note may be converted at any time before December 31,
1998 into up to 1,111,111 shares of Common Stock at a price of $9.00 per share.
The TRW Convertible Note must be converted immediately prior to the closing of
an underwritten public offering of Common Stock in which gross proceeds to the
Company are at least $15 million and in which the offering price to the public
is at least $12.00 per share and implies a pre-financing fully diluted valuation
of the Company of at least $75 million. If the initial public offering price of
shares of Common Stock in this offering is $12.00 per share or more, the TRW
Convertible Note will automatically be converted into 1,111,111 shares of Common
Stock immediately prior to the closing of this offering. If such price is less
than $12.00 per share, however, there will be no mandatory conversion, and the
TRW Convertible Note will continue to represent debt of the Company, unless
converted at the option of TRW.
    
 
   
     As part of the TRW Convertible Note financing arrangement, the Company
issued to TRW a warrant (the "Deficit Warrant") for the purchase of up to
1,111,111 shares of Common Stock at a price of $9.00 per share. The Deficit
Warrant is exercisable only to the extent that the TRW Convertible Note is not
converted into Common Stock. If the TRW Convertible Note is converted into
Common Stock in full, the Deficit Warrant will terminate at such time without
being exercised. If the TRW Convertible Note is not converted in full, the
Deficit Warrant will remain outstanding and will not terminate until the earlier
of the full conversion of the TRW Convertible Note or December 31, 1998.
    
 
  TRW Warrant
 
     The TRW Warrant provides for the purchase of up to 1,000,000 shares of
Common Stock at a price of $10.00 per share. The TRW Warrant first becomes
exercisable on the date that the Company's wafer fabrication facility becomes
operational, and thereafter must be exercised before the first to occur of (i)
the second anniversary of such date and (ii) 90 days after the Company has
provided notice to TRW that the current market price of the Common Stock is, and
has been for at least 20 consecutive trading days, greater than $12.00 per
share. If the Company's wafer fabrication facility does not become operational
by December 31, 1998, the TRW Warrant will terminate and be of no further force
or effect.
 
  Supply Agreement
 
     Under the terms of the Supply Agreement, the Company has agreed to purchase
from TRW, and TRW has agreed to sell to the Company, certain minimum quantities
of three-inch GaAs HBT processed wafers and four-inch GaAs epitaxial wafer
starting material until December 31, 2000. See "Risk Factors -- Dependence on
TRW" and "Business -- Strategic Relationship with TRW."
 
                                       50
<PAGE>   55
 
  Standstill Agreement
 
     TRW has agreed with the Company and the current holders of Preferred Stock
that, before the fifth anniversary of the closing of this offering, it will not,
and will cause its affiliates not to, (i) acquire, offer to acquire or agree to
acquire, directly or indirectly, any voting securities or rights or options to
acquire any assets of the Company or any voting securities of the Company in
excess of the lesser of (a) 40% of the Company's equity securities or (b) the
actual maximum percentage of the Company's equity securities owned by TRW
(assuming conversion by TRW of all of its convertible securities and the
exercise of any warrants or options held by TRW), calculated on a fully diluted
basis; (ii) make any public announcement with respect to, or submit any proposal
for, any extraordinary transaction involving the Company or its securities or
assets; (iii) make, or in any way participate in, any solicitation of proxies to
vote, or seek to advise or influence any person or entity with respect to the
voting of, any voting securities of the Company; (iv) form, join or in any way
participate in a "group" within the meaning of the Exchange Act with respect to
any voting securities of the Company; and (v) solicit or encourage any person to
propose a business combination or similar transaction with, or a change in
control of, the Company. Notwithstanding the foregoing, if any party makes a
bona fide offer to purchase all of the outstanding shares of the Company, TRW
will be entitled during the 30-day period following notification of such offer
to make a counterproposal for all outstanding shares of the Company on the same
or better terms and conditions as provided in the offer.
 
OTHER TRANSACTIONS
 
     On August 4, 1995, the Company entered into a note and warrant purchase
agreement with a subsidiary of Allen Telecom, which is a shareholder of the
Company and of which Erik H. van der Kaay, who is a director of the Company, is
Executive Vice President. See "Management -- Directors and Executive Officers"
and "Principal and Selling Shareholders." This agreement provided for the
borrowing by the Company of up to $2,000,000 and for the issuance to such
subsidiary of warrants to purchase up to 109,091 shares of Common Stock at a
price of $2.75 per share. On August 7, 1995, the Company borrowed $1,000,000
from such subsidiary pursuant to this agreement, which amount earned interest at
a rate equal to the prime rate of interest as reported in the Wall Street
Journal plus one percent, and issued a warrant for the purchase of up to 54,546
shares of Common Stock for $2.75 per share. On November 10, 1995, the Company
borrowed an additional $500,000 pursuant to this agreement, at the same rate of
interest, and issued a warrant for the purchase of 27,272 shares of Common Stock
for $2.75 per share. Pursuant to the terms of this second warrant, and by virtue
of the closing of the sale of 1,818,783 shares of Class C Preferred Stock on
November 22, 1995, the number of shares purchasable under this warrant was
reduced to 12,400 and the purchase price was increased to $6.048 per share. The
Company satisfied its obligations to pay principal and interest on amounts
borrowed under this agreement on November 22, 1995, when it repaid $454,279 in
cash and issued an aggregate of 178,071 shares of Class C Preferred Stock to the
Allen Telecom subsidiary, which shares are now owned directly by Allen Telecom.
Allen Telecom continues to hold warrants for the purchase of an aggregate of
66,946 shares of Common Stock; the warrant to purchase up to 54,546 shares for
$2.75 per share expires on August 6, 2000 and the warrant to purchase 12,400
shares for $6.048 per share expires on November 9, 2000.
 
     The Company and all of the current holders of Preferred Stock are party to
an agreement pursuant to which such holders have certain rights to require the
Company to register the sale of equity securities of the Company held by them,
or to include such securities in a registration initiated by the Company. See
"Description of Capital Stock -- Registration Rights."
 
     The Company has granted options to purchase Common Stock under the 1992
Option Plan to certain executive officers. See "Management -- Option Grants
During Fiscal 1996," "-- Stock Option Plans -- 1992 Stock Option Plan" and
"Principal and Selling Shareholders."

                       PRINCIPAL AND SELLING SHAREHOLDERS
 
     The following table sets forth information with respect to the beneficial
ownership of Common Stock as of March 31, 1997, and as adjusted to reflect the
sale of shares of Common Stock offered by the Company and the Selling
Shareholders hereby (assuming no exercise of the Underwriters' over-allotment
option), by (i) each person known by the Company to own beneficially five
percent or more of the Company's outstanding shares of Common Stock, (ii) each
director of the Company, (iii) the Named Executive Officers and (iv) all current
directors and executive officers as a group. Beneficial ownership is determined
in accordance with the rules of the Commission. In computing the number of
shares beneficially owned by a person and the percentage ownership of that
person, shares of Common Stock subject to options or warrants held by that
person that are currently exercisable or that are or may become exercisable
within 60 days of the date hereof are deemed outstanding. Such shares, however,
are not deemed outstanding for the purposes of computing the percentage
ownership of any other person. Except as indicated in the footnotes to this
table and pursuant to applicable community property laws, each shareholder named
in the table has sole voting and investment power with respect to the shares set
forth opposite such shareholder's name.

                          DESCRIPTION OF CAPITAL STOCK
 
   
     Upon completion of this offering, the authorized capital stock of the
Company will consist of 50,000,000 shares of Common Stock, no par value, and
5,000,000 shares of Preferred Stock, of which 13,740,330 shares of Common Stock
and no shares of Preferred Stock will be issued and outstanding. Upon completion
of this offering, and assuming no conversion of the TRW Convertible Note and no
exercise of outstanding options or warrants, the Company will have 3,287,478
shares of Common Stock reserved for issuance pursuant to the TRW Convertible
Note and outstanding options and warrants, including a warrant that the Company
may issue in the event certain financing is provided. All outstanding shares of
Common Stock are, and the shares of Common Stock offered hereby will be, when
issued, duly authorized, validly issued, fully paid and nonassessable shares of
Common Stock of the Company. As of March 31, 1997, there were 14 record holders
of Common Stock.
    
 
COMMON STOCK
 
     The holders of Common Stock are entitled to one vote per share on all
matters on which the holders of Common Stock are entitled to vote and do not
have cumulative voting rights in the election of directors. Holders of Common
Stock are entitled to receive dividends when, as and if declared by the
Company's Board of Directors out of funds legally available therefor. In the
event of the liquidation, dissolution or winding up of the Company, holders of
Common Stock will be entitled to share ratably in the assets, if any, available
for distribution after payment of all creditors and the liquidation preferences
on any outstanding shares of Preferred Stock. Holders of Common Stock have no
preemptive rights to subscribe for any additional securities of any class which
the Company may issue, nor any conversion, redemption or sinking fund rights.
The rights and privileges of holders of Common Stock are subject to the
preferences of any shares of Preferred Stock that the Company may issue in the
future.
 
PREFERRED STOCK
 
     The Company may issue shares of Preferred Stock in one or more classes or
series within a class as may be determined by the Company's Board of Directors,
who may establish, from time to time, the number of shares to be included in
each class or series, may fix the designation, powers, preferences and rights of
the shares of each such class or series and any qualifications, limitations or
restrictions thereof, and may increase or decrease the number of shares of any
such class or series without any further vote or action by the shareholders. Any
Preferred Stock so issued by the Board of Directors may rank senior to the
Common Stock with respect to the payment of dividends or amounts upon
liquidation, dissolution or winding up of the Company, or both. In addition, any
such shares of Preferred Stock may have class or series voting rights. Moreover,
under certain circumstances, the issuance of Preferred Stock or the existence of
the unissued Preferred Stock may tend to discourage or render more difficult a
merger or other change in control of the Company.
 
     As of March 31, 1997, the Company had issued and outstanding 975,000 shares
of Class A-1 Preferred Stock, 1,034,091 shares of Class A-2 Preferred Stock,
3,300,000 shares of Class B Preferred Stock and 2,645,229 shares of Class C
Preferred Stock. Effective upon consummation of this offering, all outstanding
shares of Preferred Stock will be converted automatically into Common Stock on a
one-for-one basis pursuant to their terms. No shares of Preferred Stock will be
outstanding after this offering. No dividends have been or will be paid on
outstanding shares of Preferred Stock.
 
   
TRW CONVERTIBLE NOTE AND WARRANTS
    
 
   
     The Company has outstanding the TRW Convertible Note, under which it has
borrowed $10 million from TRW, and the related Deficit Warrant. The TRW
Convertible Note and the Deficit Warrant may be converted or exercised at TRW's
option at any time before December 31, 1998 into up to an aggregate of 1,111,111
shares of Common Stock at a price of $9.00 per share, and must be converted in
the event of a public offering meeting certain criteria, at which time the
Deficit Warrant would expire without having been exercised. In the absence of a
mandatory conversion of the TRW Convertible Note, the Deficit Warrant will
    
 
                                       55
<PAGE>   60
 
   
expire on December 31, 1998. See "Certain Transactions -- TRW -- TRW Convertible
Note." The Company also has outstanding the TRW Warrant, which will become
exercisable at such time as the Company's wafer fabrication facility becomes
operational into up to 1,000,000 shares of Common Stock at an exercise price of
$10.00 per share. The TRW Warrant will terminate (i) upon the earlier of (a) the
second anniversary of the date it becomes exercisable or (b) 90 days after the
Common Stock has traded for at least 20 consecutive trading days at a price
greater than $12.00 per share or (ii) if the Company's wafer fabrication
facility does not become operational by December 31, 1998 or such other date as
may be agreed upon. See "Certain Transactions -- TRW -- TRW Warrant." In
addition, in connection with certain financing transactions, the Company has
issued or agreed to issue the Lender Warrants, which comprise (i) two warrants
granted to Allen Telecom to purchase up to 54,546 shares for $2.75 per share and
up to 12,400 shares for $6.048 per share, which expire on August 6, 2000 and
November 9, 2000, respectively (See "Certain Transactions -- Other
Transactions"), (ii) a warrant granted to a lender to purchase up to 41,322
shares of Common Stock for $9.00 per share that expires on February 25, 2002,
and (iii) a warrant that the Company has agreed to issue to such lender in the
event certain financing is provided, which warrant would be exercisable into up
to 41,323 shares of Common Stock for $9.00 per share and have a term of five
years.
    
 
CERTAIN PROVISIONS OF THE ARTICLES OF INCORPORATION AND BYLAWS
 
  General
 
     A number of provisions of the Company's articles of incorporation and
bylaws deal with matters of corporate governance and the rights of shareholders.
Certain of these provisions may be deemed to have an anti-takeover effect and
may delay or prevent takeover attempts not first approved by the Board of
Directors (including takeovers that certain shareholders may deem to be in their
best interests). These provisions also could delay or frustrate the removal of
incumbent directors or the assumption of control by shareholders. The Company
believes that these provisions are appropriate to protect the interests of the
Company and all of its shareholders.
 
  Certain Business Combinations
 
     The Company's articles of incorporation require that any business
combination, as defined in the articles, to be entered into by the Company with
a person or entity beneficially owning 15% or more of the Company's outstanding
voting shares (an "Interested Shareholder") be approved by the affirmative vote
of the holders of at least 60% of the outstanding voting shares, other than
shares held by such Interested Shareholder, or, alternatively, by a majority of
certain members of the Board of Directors not affiliated with such Interested
Shareholder. The business combinations that are subject to these provisions
include a merger or share exchange with an Interested Shareholder, certain sales
to an Interested Shareholder of assets of the Company and certain issuances or
transfers to an Interested Shareholder by the Company or any of its subsidiaries
of equity securities of the Company or such subsidiary. These provisions will
make a takeover of the Company more difficult and may have the effect of
diminishing the possibility of certain types of "front-end loaded" acquisitions
of the Company or other unsolicited attempts to acquire the Company.
 
  Advance Notice Requirements for Shareholder Proposals and Director Nominations
 
     The Company's bylaws provide that a special meeting of shareholders may be
called only by the Board of Directors and certain designated officers of the
Company. Special meetings may not be called by the shareholders. The Company's
bylaws establish advance notice procedures for shareholder proposals and the
nomination, other than by or under the direction of the Board of Directors or a
committee thereof, of candidates for election as directors. These procedures
provide that the notice of shareholder proposals and shareholder nominations for
the election of directors must be in writing, contain certain specified
information and be received by the Secretary of the Company (i) in the case of
an annual meeting that is called for a date that is within 30 days before or
after the anniversary date of the immediately preceding annual meeting of
shareholders, not less than 60 days nor more than 90 days prior to such
anniversary date, and (ii) in the case of an annual meeting that is called for a
date that is not within 30 days before or after the anniversary date of the
immediately preceding annual meeting or, in the case of a special meeting of
shareholders, not later than the
 
                                       56
<PAGE>   61
 
close of business on the tenth day following the day on which notice of the date
of the meeting was mailed or public disclosure of the date of the meeting was
made, whichever occurs first. These provisions may preclude some shareholders
from bringing matters before the shareholders at any annual or special meeting,
including making nominations for directors.
 
  Amendment of Articles and Bylaws
 
     Subject to the North Carolina Business Corporation Act, the Company's
articles of incorporation may be amended by the affirmative vote of a majority
of the outstanding shares entitled to vote thereon. Notwithstanding the
foregoing, the amendment or repeal of certain provisions of the articles
relating to the shares which the Company shall have authority to issue, the
approval of certain business combinations as described above and certain other
matters require the affirmative vote of the holders of 60% of the Company's
voting securities, other than securities held by an Interested Shareholder. The
articles further provide that certain provisions of the bylaws relating to the
size and composition of the Board of Directors and meetings of shareholders may
be amended by the shareholders, except in certain specified circumstances, only
by the affirmative vote of the holders of 60% of the outstanding shares of
voting securities, other than securities held by an Interested Shareholder.
Moreover, the articles provide that the Board of Directors may repeal, amend or
adopt any bylaw adopted, amended or repealed by the shareholders. These
provisions will make it more difficult for shareholders to amend the articles or
bylaws.
 
  Anti-takeover Legislation
 
     Pursuant to the Company's articles of incorporation, the Company has
elected not to be governed by the North Carolina Control Share Act, which
restricts the right of certain shareholders who acquire specified amounts of the
Common Stock from voting those shares without certain approval by other
shareholders of the Company, and the North Carolina Shareholder Protection Act,
which imposes certain requirements for approval of transactions between the
Company and a shareholder beneficially owning in excess of 20% of the Common
Stock.
 
REGISTRATION RIGHTS
 
     Pursuant to an agreement between the Company and the current holders of
Preferred Stock (the "Investor Holders"), the Investor Holders are entitled to
certain rights as described below with respect to the registration under the
Securities Act of the sale of up to 12,898,952 shares of Common Stock (the
"Registrable Securities"). Such number represents 7,954,320 shares issuable upon
conversion of Preferred Stock, 2,683,930 shares of Common Stock held by TRW
(except that none of these shares will be Registrable Securities until released
from the terms of the restricted stock agreement between the Company and TRW;
see "Certain Transactions -- TRW"), 1,111,111 shares of Common Stock issuable in
connection with the conversion of the TRW Convertible Note and up to 1,149,591
shares of Common Stock issuable upon the exercise of the TRW Warrant and the
Lender Warrants. See "Certain Transactions -- TRW" and "-- Other Transactions."
 
     Subject to certain exceptions, if the Company proposes to register the sale
of any Common Stock for its own account or the account of others, the Investor
Holders are entitled to notice of such registration and to include the
Registrable Securities therein at the Company's expense. The Company has
obtained waivers of the foregoing rights from the Investor Holders in connection
with this offering. After June 6, 1997, the Investor Holders of at least 60% of
the Registrable Securities may require the Company to file a registration
statement at the Company's expense with respect to the Registrable Securities
held by such Investor Holders and such other Registrable Securities as other
Investor Holders may wish to include. The Company must use its diligent best
efforts to effect such a registration. Moreover, after the Company becomes
eligible for the use of a registration statement on Form S-3, the Investor
Holders will have the right to request the Company, at its expense, to effect an
unlimited number of registrations on Form S-3 (but no more than one registration
every six months) for any sale of Registrable Securities having a proposed
aggregate offering price (before deduction of underwriting discounts and
expenses of sale) of at least $500,000. The Company must use its best efforts to
effect such registrations.
 
                                       57
<PAGE>   62
 
     The foregoing registration rights are subject to certain conditions and
limitations, including (i) the right of the Company not to effect a requested
registration during the 90 days following this offering and (ii) the right of
the underwriters of an offering undertaken at the Company's initiative to limit
the number of Registrable Securities in the offering, unless other holders of
the Company's securities are permitted to include their securities in the
offering. The Investor Holders are subject to additional limitations with
respect to the exercise of registration rights by virtue of certain contractual
provisions. See "Underwriting."
 
TRANSFER AGENT AND REGISTRAR
 
     The Transfer Agent and Registrar for the Company's Common Stock is First
Union National Bank.
 
LISTING
 
     The Common Stock has been approved for quotation on the Nasdaq National
Market under the symbol "RFMD."
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Prior to this offering, there has been no market for the Common Stock of
the Company. Future sales of substantial amounts of Common Stock in the public
market could adversely affect market prices prevailing from time to time.
Furthermore, because only a limited number of shares will be available for sale
shortly after this offering because of certain contractual and legal
restrictions on resale as described below, sales of substantial amounts of
Common Stock of the Company in the public market after the restrictions lapse
could adversely affect the prevailing market price and the ability of the
Company to raise equity capital in the future.
 
   
     Upon completion of this offering, the Company will have outstanding an
aggregate of 13,740,330 shares of Common Stock, assuming no exercise of the
Underwriters' over-allotment option, no exercise of outstanding options and
warrants to purchase Common Stock and no conversion of the TRW Convertible Note.
Of these shares, the 2,537,000 shares sold in this offering will be freely
tradeable without restriction or further registration under the Securities Act
(except for any shares purchased by "affiliates," as that term is defined in
Rule 144 under the Securities Act ("Affiliate")). Of the remaining shares of
Common Stock, the Company believes that 6,804,354 shares (the "Affiliate
Shares") will be held by Affiliates and 4,398,976 shares (the "Nonaffiliate
Shares") will be held by nonaffiliates of the Company. All of such shares of
Common Stock are "restricted securities" as that term is defined in Rule 144
under the Securities Act ("Restricted Shares"). Restricted Shares may be sold in
the public market only if registered or if they qualify for an exemption from
registration under Rules 144 (including Rule 144(k)) or 701 promulgated under
the Securities Act, which rules are summarized below. As a result of the current
provisions of Rules 144 (including Rule 144(k)) and 701, the Company believes
Restricted Shares will be available for sale in the public market as follows:
(i) no Restricted Shares will be eligible for immediate sale on the effective
date of this offering; (ii) 8,519,400 Restricted Shares will be eligible for
sale upon expiration of lock-up agreements 180 days after the date of this
Prospectus; and (iii) 2,683,930 Affiliate Shares will become eligible for sale
at such time as they are released from the terms of the Restricted Stock
Agreement. See "Certain Transactions -- TRW -- Restricted Stock Agreement." In
addition, 1,111,111 shares of Common Stock issuable to TRW upon conversion of
the TRW Convertible Note will be eligible for immediate sale 180 days after the
date of this Prospectus upon expiration of a lock-up agreement executed by TRW.
    
 
     Upon completion of this offering, the holders of certain shares of Common
Stock, or their transferees, will be entitled to certain rights with respect to
the registration of such shares under the Securities Act. See "Description of
Capital Stock -- Registration Rights." Registration of such shares under the
Securities Act would result in such shares becoming freely tradeable without
restriction under the Securities Act (except for shares purchased by Affiliates)
immediately upon the effectiveness of such registration.
 
   
     In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this Prospectus, a person (or persons whose shares are aggregated)
who has beneficially owned Restricted Shares for at least one year (including
the holding period of any prior owner except an Affiliate) would be entitled to
sell within any
    
 
                                       58

three-month period a number of shares that does not exceed the greater of: (i)
one percent of the number of shares of Common Stock then outstanding (which will
equal approximately 137,403 shares immediately after this offering); or (ii) the
average weekly trading volume of the Common Stock on the Nasdaq National Market
during the four calendar weeks preceding the filing of a notice on Form 144 with
respect to such sale. Sales under Rule 144 are also subject to certain manner of
sale provisions and notice requirements and to the availability of current
public information about the Company. Under Rule 144(k), a person who is not
deemed to have been an Affiliate of the Company at any time during the 90 days
preceding a sale, and who has beneficially owned the shares proposed to be sold
for at least two years (including the holding period of any prior owner except
an Affiliate), is entitled to sell such shares without complying with the manner
of sale, public information, volume limitation or notice provisions of Rule 144;
therefore, unless otherwise restricted, "144(k) shares" may therefore be sold
immediately upon the completion of this offering. In general, under Rule 701 of
the Securities Act as currently in effect, any employee, consultant or advisor
of the Company who purchased shares from the Company in connection with a
compensatory stock or option plan or other written agreement is eligible to
resell such shares 90 days after the effective date of this offering in reliance
on Rule 144, but without compliance with certain restrictions, including the
holding period, contained in Rule 144.
    
 
     All of the Common Shares held by existing shareholders or acquired in the
future by such shareholders or by any director or executive officer of the
Company are subject to lock-up agreements with the Underwriters and may not be
sold or otherwise transferred until 180 days after the date of this Prospectus
without the consent of Montgomery Securities, on behalf of the Underwriters.
Montgomery Securities, on behalf of the Underwriters, may, in its sole
discretion and at any time without notice, release all or any portion of the
securities subject to these lock-up agreements.
 
   
     The Company intends to file registration statements under the Securities
Act covering shares of Common Stock reserved for issuance under the 1992 Option
Plan, the 1997 Option Plan, the Directors' Option Plan and the Stock Purchase
Plan. Based on the number of options outstanding and shares reserved for
issuance or anticipated to be reserved as issuance under these plans, such
registration statements would cover approximately 3,426,000 shares, including up
to 463,567 shares that were or may be issued upon the exercise of stock options
during 1997. See "Management -- Stock Option Plans." Such registration
statements are expected to be filed and become effective as soon as practicable
after the effective date of this offering. Accordingly, shares registered under
such registration statements will, subject to Rule 144 volume limitations
applicable to Affiliates, be available for sale in the open market, unless such
shares are subject to vesting restrictions with the Company or the lock-up
agreements described above. As of March 31, 1997, options to purchase 1,031,336
shares of Common Stock were issued and outstanding under the 1992 Option Plan
and options covering 18,080 shares of Common Stock had been exercised. See
"Management -- Compensation of Directors" and "-- Stock Option Plans."

</TABLE>
 
     The Representatives have advised the Company and the Selling Shareholders
that the Underwriters initially propose to offer the shares of Common Stock to
the public on the terms set forth on the cover page of this Prospectus. The
Underwriters may allow to selected dealers a concession of not more than
$          per share, and the Underwriters may allow, and such dealers may
reallow, a concession of not more than $          per share to certain other
dealers. After the initial public offering, the offering price and other selling
terms may be changed by the Representatives. The Common Stock is offered subject
to receipt and acceptance by the Underwriters, and to certain other conditions,
including the right to reject orders in whole or in part.
 
   
     The Company has granted an option to the Underwriters, exercisable during
the 30-day period after the date of this Prospectus, to purchase up to a maximum
of 380,550 additional shares of Common Stock to cover over-allotments, if any,
at the same price per share as the initial 2,537,000 shares to be purchased by
the Underwriters. To the extent that the Underwriters exercise this option, each
of the Underwriters will be committed to purchase such additional shares in
approximately the same proportion as set forth in the above table. The
Underwriters may purchase such shares only to cover over-allotments made in
connection with this offering.
    
 
                                       60
<PAGE>   65
 
     At the request of the Company, the Underwriters have reserved approximately
120,000 of the shares of Common Stock offered by the Company hereby for sale at
the initial public offering price to directors, officers, employees and certain
individuals associated with the Company, its directors, its officers or its
employees. The number of shares of Common Stock available to the public will be
reduced to the extent such persons purchase such reserved shares. Any reserved
shares that are not so purchased will be offered by the Underwriters to the
general public on the same basis as the other shares offered hereby.
 
     The Underwriting Agreement provides that the Company and the Selling
Shareholders will indemnify the Underwriters and their employees and controlling
persons against certain liabilities, including civil liabilities under the
Securities Act, or will contribute to payments the Underwriters may be required
to make in respect thereof.
 
     All of the shares of Common Stock currently held by existing shareholders
or acquired in the future by such shareholders or by any director or executive
officer of the Company are subject to lock-up agreements with the Underwriters
and may not be sold or otherwise transferred until 180 days after the date of
this Prospectus without the consent of Montgomery Securities, on behalf of the
Underwriters. Montgomery Securities, on behalf of the Underwriters, may, in its
sole discretion and at any time without notice, release all or any portion of
the securities subject to these lock-up agreements.
 
     Prior to this offering, there has been no public market for the shares of
Common Stock of the Company. Consequently, the initial public offering price
will be determined by negotiations between the Company and the Representatives.
Among the factors to be considered in such negotiations are the history of, and
prospects for, the Company and the industry in which it competes, an assessment
of the Company's management, its past and present operations and financial
performance, the prospects for future earnings of the Company, the present state
of the Company's development, the general condition of the securities markets at
the time of the offering, and the market price for publicly traded common stock
of comparable companies in recent periods.
 
     Certain persons participating in this offering may engage in transactions,
including the entry of stabilizing bids, syndicate covering transactions or the
imposition of penalty bids, which may involve the purchase of Common Stock on
the Nasdaq National Market or otherwise. A stabilizing bid means the placing of
any bid or the effecting of any purchase for the purpose of pegging, fixing or
maintaining the price of the Common Stock. A syndicate covering transaction
means the placing of any bid on behalf of the underwriting syndicate or the
effecting of any purchase to reduce a short position created in connection with
the offering. A penalty bid means an arrangement that permits the Underwriters
to reclaim a selling concession from a syndicate member in connection with the
offering when shares of Common Stock sold by the syndicate member are purchased
in syndicate covering transactions. Such transactions may stabilize or maintain
the market price of the Common Stock at a level above that which otherwise might
prevail in the open market and, if commenced, may be discontinued at any time.
 
     The Representatives have informed the Company that the Underwriters do not
expect to make sales of shares of Common Stock offered hereby to accounts over
which they exercise discretionary authority in excess of five percent of the
number of shares of Common Stock offered hereby.
 
                                 LEGAL MATTERS
 
     The validity of the Common Stock offered hereby will be passed upon for the
Company and the Selling Shareholders by Womble Carlyle Sandridge & Rice, PLLC,
Winston-Salem, North Carolina. Certain legal matters in connection with this
offering will be passed upon for the Underwriters by Hale and Dorr LLP,
Washington, D.C.

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors
RF Micro Devices, Inc.
 
   
     We have audited the balance sheets of RF Micro Devices, Inc. as of March
31, 1996 and 1997 and the related statements of operations, redeemable
convertible preferred stock and shareholders' deficiency and cash flows for each
of the three years in the period ended March 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
    
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
   
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of RF Micro Devices, Inc. at
March 31, 1996 and 1997 and the results of its operations and its cash flows for
each of the three years in the period ended March 31, 1997 in conformity with
generally accepted accounting principles.

1. DESCRIPTION OF COMPANY BUSINESS
 
     The Company designs, develops and markets proprietary analog radio
frequency and immediate frequency integrated circuits ("RFICs") for wireless
applications. These applications include cellular and cordless telephones, PCS
handsets, wireless local area data networks, wireless local loop handsets,
wireless security systems and remote meter reading systems. The Company ceased
being a development stage enterprise during the year ended March 31, 1995.
 
     The Company offers products fabricated under three distinct process
technologies: silicon bipolar transistor, gallium arsenide metal semiconductor
field effect transistor and gallium arsenide heterojunction bipolar transistor
("GaAs HBT"). In June 1996, the Company and TRW Inc. ("TRW") entered into a
license arrangement under which TRW exclusively licensed its GaAs HBT and
related wafer fabrication technologies to the Company for commercial wireless
applications operating at frequencies less than 10 GHz. The Company's GaAs HBT
integrated circuits are manufactured for the Company by TRW through a
proprietary process developed by TRW. In order to exploit this licensed
technology, a third party developer is currently constructing a GaAs HBT
four-inch wafer fabrication facility adjacent to the Company's executive offices
in Greensboro, North Carolina, which the Company will lease upon completion.
This facility is currently scheduled to be operating at commercial levels in the
second half of 1998. Until then, the Company will purchase all or substantially
all of its GaAs HBT parts from TRW.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Cash and Cash Equivalents
 
     Cash equivalents consist of demand deposit accounts, money market funds and
temporary, highly liquid investments with original maturities of three months or
less.
 
  Cash Restricted for Capital Additions
 
     Proceeds from the sale of Class C preferred stock to TRW (Note 13) and
proceeds from the $10 million note payable agreement with TRW (Note 6) are to be
used exclusively in funding the planning, construction and the operational,
working capital and related requirements of the wafer fabrication facility.
Unused proceeds from these instruments are classified as restricted cash on the
balance sheet.
 
  Property and Equipment
 
     Property and equipment are stated at cost. Depreciation of property and
equipment is provided using the straight-line method over the estimated useful
lives, ranging from 5 to 7 years, of the related assets.
 
  Inventories
 
     Inventories are stated at the lower of cost or market determined using the
average cost method. The Company's business is subject to the risk of
technological and design changes. The Company provides for potentially obsolete
or slow moving inventory based on management's analysis of inventory levels and
future sales forecasts at the end of each accounting period.
 
  Accounting Periods
 
   
     The Company uses a 52 or 53 week fiscal year ending on the Saturday closest
to March 31 of each year. Each of the fiscal years ended April 1, 1995, March
30, 1996 and March 29, 1997 were 52 week years. For purposes of financial
statement presentation, each fiscal year is described as having ended on March
31.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Revenue Recognition
 
     Revenue from product sales is recognized when products are shipped. The
Company also enters into engineering agreements with certain customers relating
to the development of customer specific applications. Revenue is recognized for
engineering contracts when contract milestones are met.
 
     The Company's products generally carry a one or two year warranty against
defects depending on the specific type of product. The Company provides for
estimated warranty costs in the period the related sales are made.
 
  Pro Forma Presentation of Liabilities and Shareholders' Equity (Unaudited)
 
   
     The Company has issued and outstanding four classes of redeemable
convertible preferred stock which automatically convert into common stock with
the closing of an initial public offering of the Company's common stock. The pro
forma presentation in the accompanying balance sheet gives effect to the
conversion of the preferred stock on the assumption that the Company will become
a public entity and the conditions for conversion, as described in Note 9, will
be satisfied.
    
 
  Risks and Uncertainties
 
     Pursuant to the strategic alliance with TRW (Note 13), TRW has granted to
the Company certain licenses to produce certain GaAs HBT products. The Company
plans to lease from a third party real estate developer a wafer fabrication
facility and begin manufacturing its own GaAs HBT products covered by such
licenses. These licenses may be terminated by TRW if the fabrication facility is
not operational by December 31, 1998. A decision by TRW to terminate the license
agreements or make them non-exclusive would have a material adverse effect on
the Company's operations.
 
   
     Until the Company is able to internally produce GaAs HBT products, it will
continue to purchase all such products from TRW. Sales of GaAs HBT products
represented 85% of the Company's total revenue for 1997. Failure by TRW to
continue to supply adequate quantities of product to the Company or the
inability to successfully transfer the GaAs HBT technology to the Company in a
timely manner would have a material adverse effect on the Company.
    
 
   
     The demand for certain of the Company's products has currently exceeded
supply capacity and consequently the Company has been unable to meet requested
delivery times and quantity requirements. One of the Company's most significant
customers, a company which is a subsidiary of one of the Company's corporate
shareholders, has decided to obtain these products from sources other than the
Company. This customer's purchases represented 15%, 31% and 32% of the Company's
revenue for the years ended March 31, 1995, 1996 and 1997. Continuation of
capacity limitations may cause existing or potential customers to develop other
sources of supply.
    
 
   
  Use of Estimates
    
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ materially from those estimates.

  Sales and Accounts Receivable
 
     The Company operates in a single industry and is engaged in the design and
sale of integrated circuits. Revenues from significant customers, those
representing 10% or more of total sales for the respective periods, are
summarized as follows:

     The Company's principal financial instrument subject to potential
concentration of credit risk is accounts receivable which are unsecured. The
Company's exposure to credit loss in the event that payment from a customer is
not received for revenue recognized equals the net outstanding accounts
receivable balance from that customer.
 
     The Company provides an allowance for doubtful accounts equal to estimated
losses expected to be incurred in the collection of accounts receivable.
 
  Research and Development
 
     The Company charges all research and development costs to expense as
incurred.
 
  Income Taxes
 
     The Company accounts for income taxes under Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS 109"). Under
SFAS 109, the liability method is used in accounting for income taxes and
deferred tax assets and liabilities are determined based on differences between
the financial reporting and tax bases of assets and liabilities.
 
  Stock Based Compensation
 
     The Company accounts for stock options in accordance with APB Opinion No.
25, "Accounting for Stock Issued to Employees." Under APB No. 25, no
compensation expense is recognized for stock options issued to employees at fair
value. For stock options granted at exercise prices below the deemed fair value,
the Company records deferred compensation expense for the difference between the
exercise price of the shares and the deemed fair market value. The deferred
compensation expense is amortized ratably over the vesting period of the
individual options.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
   
     In October 1995, the FASB issued Statement of Financial Accounting
Standards No. 123, "Accounting for Stock Based Compensation" ("SFAS 123"), which
provides an alternative to APB No. 25 in accounting for stock based compensation
issued to employees. SFAS 123 provides for a fair value based method of
accounting for employee stock options and similar equity instruments. However,
companies that continue to account for stock based compensation arrangements
under APB No. 25 are required by SFAS 123 to disclose the pro forma effect on
net (loss) income and (loss) earnings per share as if the fair value based
method prescribed by SFAS 123 had been applied. The disclosure requirements are
effective for fiscal years beginning after December 31, 1995, or upon initial
adoption of the statement, if earlier. The Company plans to continue to account
for stock based compensation using the provisions of APB 25 and has adopted the
disclosure requirements of SFAS 123 in 1997 (see Note 10).
    
 
  Impact of Recently Issued Accounting Standards
 
   
     In March 1995, the FASB issued Statement No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of"
("SFAS 121"), which requires impairment losses to be recorded on long-lived
assets used in operations when indicators of impairment are present and the
undiscounted cash flows estimated to be generated by those assets are less than
the assets' carrying amount. SFAS 121 also addresses the accounting for
long-lived assets that are expected to be disposed of. SFAS 121 is effective for
fiscal years beginning after December 15, 1995. The Company's adoption of SFAS
121 during 1997 did not have a material effect on the Company's financial
statements.

5. LINES OF CREDIT AND LONG-TERM DEBT
 
   
     During 1997, the Company increased its revolving working capital line of
credit to an amount equal to 80% of eligible accounts receivable up to a maximum
of $7 million. The line commitment expires on December 19, 1997 at which time
the balance is due and payable. At March 31, 1996 and 1997, the outstanding
balance was $350,000. This line bears interest at the prime rate plus 0.75%
(9.00% at March 31, 1996 and 9.25% at March 31, 1997) and is collateralized by
all the Company's assets. The effective interest rate on outstanding borrowings
under the line of credit for the year ended March 31, 1996 and 1997 was
approximately 8.90% and 9.15%, respectively. The agreement contains provisions
to allow the Company to utilize the line for letters of credit and foreign
exchange contracts, none of which are outstanding for any of the periods
presented.
    
 
   
     During 1997, the Company increased its equipment line of credit to $2
million. Borrowings on this line are converted to term loans, repayable in 36
equal monthly installments at the time the draw is made. At March 31, 1996 and
1997, the outstanding balance on the equipment line notes was approximately
$158,000 and $295,000. These borrowings bear interest at the prime rate plus
1.50% (10.50% at March 31, 1996 and 11% at March 31, 1997) and are
collateralized by all the Company's assets. The effective interest rate on these
term loans for the year ended March 31, 1996 and 1997 was approximately 10.25%
and 10.65%, respectively.
    
 
   
     Future year maturities under the equipment term loans at March 31, 1997 are

6. NOTE PAYABLE TO SHAREHOLDER
 
     The note payable to shareholder consists of a $10 million subordinated
convertible note issued on June 6, 1996 to a corporate shareholder of the
Company (see Note 13). The note bears interest at 6% and all principal

and accrued interest is payable in full on June 6, 2003. The Company incurred
interest expense of approximately $301,000 related to this note during 1997, of
which approximately $40,000 has been capitalized. Payment of interest will be
forfeited if and when the note is converted into the Company's capital stock.
    
 
     At the holder's option, all or any portion of the then outstanding
principal of the note is convertible at a conversion price of $9.00 per share.
The conversion price is subject to change in the event certain equity
transactions, as defined in the agreement, occur. If conversion occurs prior to
the closing of a public offering which results in gross proceeds of not less
than $15 million and a post-IPO market capitalization of at least $75 million,
the outstanding principal will be converted into newly created preferred stock
of the Company. If conversion occurs after a public offering meeting the
criteria specified above, the conversion shall be made into the Company's common
stock. Mandatory conversion into shares of the Company's common stock will
occur, at $9.00 per share, in full immediately prior to the closing of a public
offering in which the per share price is at least $12.00. The Company has
reserved a sufficient number of shares of its authorized but unissued stock to
permit conversion.
 
   
     In connection with the issuance of the $10 million subordinated convertible
note, the Company issued a warrant to purchase at any time through December 31,
1998 up to 1,111,111 shares of common stock, less the number, if any, that have
been acquired through conversion of the related $10 million note. Should the
related note convert into 1,111,111 shares of stock, the warrant shall become
null and void. The warrant has an exercise price of $9.00 per share, which is
subject to change in the event certain equity transactions, as defined in the
agreement, occur.

     At March 31, 1997, the Company had net operating loss carryforwards and
research and experimental credit carryforwards of approximately $3,258,000 and
$741,000, respectively, for income tax purposes. The tax benefits of these items
are reflected in the accompanying table of deferred tax assets and liabilities.
If not used, these carryforwards begin to expire in 2010. U.S. tax rules impose
limitations on the use of net operating losses following certain changes in
ownership. If such change occurs, the limitation could reduce the amount of
these benefits that would be available to offset future taxable income each
year, starting with the year of ownership change.
    
 
8. 401(K) PLAN
 
   
     Each employee is eligible to participate in the Company's fully qualified
401(k) plan after three months of service. An employee may invest a maximum of
15% of pretax earnings in the plan. Employer contributions to the plan are made
at the discretion of the Company and its Board of Directors. An employee is
fully vested in the employer contribution portion of the plan after completion
of 5 continuous years of service. The Company did not make any contributions to
the plan during the years ended March 31, 1995, 1996 or 1997.
    
 
9. REDEEMABLE CONVERTIBLE VOTING PREFERRED STOCK
 
     The Company's mandatorily redeemable preferred stock consists of Class A-1
redeemable convertible preferred stock, no par value, 1,000,000 shares
authorized, 975,000 shares issued and outstanding; Class A-2 redeemable
convertible preferred stock, no par value, 1,100,000 shares authorized,
1,034,091 shares issued and outstanding; Class B redeemable convertible
preferred stock, no par value, 3,700,000 shares authorized, 3,300,000 shares
issued and outstanding and Class C redeemable convertible preferred stock, no
par value, 2,700,000 shares authorized, 2,645,229 shares issued and outstanding.
 
     Contemporaneously with the closing of an underwritten public offering
resulting in gross proceeds of at least $15 million at a price per share which
implies a post-IPO market capitalization of the Company of at least $75 million,
each share of preferred stock shall automatically convert to common stock. The
preferred stock, which includes liquidation preferences, is convertible,
initially at the rate of one share of common stock for each share of preferred
stock. The conversion rate and value are subject to adjustment in the event of
certain changes, as defined in the articles of incorporation. Each share of
preferred stock is entitled to the number of votes per share equal to the number
of shares of common stock into which each share of preferred stock is
convertible. The preferred stock was recorded at the value received on the date
of issuance and includes redemption privileges if, on or after November 23,
2000, a public offering has not been completed. The redemption price is the
original issuance price of the preferred shares.
 
     The Company has reserved a sufficient number of its authorized shares of
common stock for the purpose of effecting the future conversion of the preferred
stock.

10. STOCK OPTIONS
 
   
     The Company has adopted an incentive stock option plan which provides for
the purchase of the Company's common stock by certain employees. Under the terms
of the plan, 20% of total shares awarded are exercisable one year after the date
of grant and 20% are exercisable for each of the following four years. Options
terminate ten years from date of grant. The Company has reserved a sufficient
number of shares of common stock for future issuance under the Stock Option
Plan.
    
 
   
     The Company has elected to follow Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" ("APB 25") and related
Interpretations in accounting for its employee stock options. The Company has
recorded deferred compensation expense of $300,000 for the difference between
the grant price and the deemed fair value of certain of the Company's common
stock options granted in 1997.
    
 
   
     Pro forma information regarding net (loss) income and (loss) earnings per
share is required by SFAS 123, and has been determined as if the Company
accounted for its employee stock options under the fair value method of SFAS
123. The fair value for these options was estimated at the date of grant using a
Black-Scholes option pricing model with the following weighted average
assumptions for the year ended March 31, 1997: risk-free interest rate of 6%, no
expected dividends, a volatility factor of .70 and a weighted average expected
life of the options of 5 years.
    
 
     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because changes in the subjective input assumption can materially
affect the fair value estimate, in management's opinion, the existing models do
not necessarily provide a reliable single measure of the fair value of its
employee stock options.
 
     For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The Company's
pro forma information follows:

12. INCOME (LOSS) PER SHARE OF COMMON STOCK
 
   
     Pro forma income (loss) per share of common stock and historical income
(loss) per share of common stock computed in accordance with APB No. 15 and
presented below are computed using the weighted average number of shares of
common stock and the dilutive effect of common stock equivalents outstanding.
The pro forma calculation assumes the conversion of all outstanding classes of
redeemable convertible pro forma stock and conversion of the convertible note
payable.
    
 
   
     In accordance with Securities and Exchange Commission Staff Accounting
Bulletins, all issuances of the Company's common and common equivalent shares,
at prices below the expected initial public offering price during the twelve
month period preceding the filing date of the initial public offering (cheap
stock), have been included in the pro forma and historical calculations as if
they were outstanding for all periods presented (using the treasury stock method
and the estimated initial public offering price).
    
 
   
     Historical (loss) income per share amounts, computed in accordance with APB
No. 15, were $(0.94), $(1.19) and $0.14 for 1995, 1996 and 1997, respectively.
Fully diluted income (loss) per share amounts are not shown as the effect is
anti-dilutive.
    
 
   
     In February 1997, the FASB issued Statement No. 128, "Earnings Per Share,"
which requires public companies to report basic and diluted earnings (loss) per
share using the calculation methodologies set forth in the statement. The
statement is effective for years ending after December 15, 1997; thus, this
pronouncement will be adopted by the Company for the fiscal year ending March
31, 1998. Application of this pronouncement to the calculation of pro forma
income per share for the year ended March 31, 1997, and continuing the
application of the cheap stock provisions discussed in the preceding paragraph,
would not have changed the pro forma income per share.
    
 
13. RELATED PARTY TRANSACTIONS
 
     During the year ended March 31, 1996, in connection with the bridge
financing which was subsequently converted to preferred stock, the Company
issued to a shareholder warrants that entitle the holder to purchase 66,946
shares of common stock at exercise prices ranging from $2.75 to $6.05 per share.
The warrants expire on dates ranging from August 2000 to November 2000. No
warrants have been exercised as of December 31, 1996.
 
     On June 6, 1996, the Company entered into a strategic alliance with TRW.
Pursuant to this alliance, the Company sold 826,445 shares of its Class C
preferred stock to TRW for net cash proceeds of $4,931,703. The Company also
entered into a $10 million subordinated, convertible promissory note agreement
with TRW, (see Note 6). The use of the proceeds from these transactions are to
be used exclusively in funding the development and construction of a wafer
fabrication facility.
 
   
     Additionally, TRW granted to the Company a worldwide right and license to
make, have made, use and sell the products manufactured in the wafer fabrication
facility. This right and license will become exclusive and perpetual upon
completion of the condition discussed below. In consideration of the license,
the Company issued to TRW 2,683,930 shares of restricted common stock valued at
$2,952,323. The common stock is restricted in that it is non-voting and
non-transferable. These restrictions will lapse when the Company successfully
utilizes the TRW technology in its manufacturing process in the fabrication
facility. If by December 31, 1998 the wafer foundry is not operational, as
defined in the agreement, TRW has the right to revoke the license and the
Company correspondingly has the right to redeem as much as one-half of the TRW
shares for a nominal amount. At the option of TRW, the license will become
non-exclusive if the Company fails to meet the following revenue goals, as
measured in accordance with generally accepted accounting principles, following
the date on which the Company's wafer fabrication facility becomes operational:
during the first year, $30 million; during the second year, $65 million; and
during the third year, $125 million.

                             RF MICRO DEVICES, INC.
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
   
     In connection with the licensing agreement, the Company issued a warrant to
TRW to purchase up to 1,000,000 shares of the Company's common stock at an
exercise price of $10.00 per share. The exercise price is subject to adjustment
in the event of certain changes, as defined by the agreement, affecting the
Company's capitalization. The TRW warrant first becomes exercisable on the date
that the Company's wafer facility becomes operational and thereafter must be
exercised before the first to occur of (i) the second anniversary of such date
and (ii) 90 days after the Company has provided notice to TRW that the current
market price of the Company's common stock is, and has been for at least 20
consecutive days, greater than $12.00 per share. If the Company's wafer facility
does not become operational by December 31, 1998, the warrant will terminate in
full. A value of $250,000 has been recorded for this warrant.
    
 
     The restricted common stock and the related warrant have an aggregate value
of $3,202,323, which represents the Company's right to use the technology and
accordingly, a related intangible asset has been recorded on the Company balance
sheet. Amortization of this intangible asset will be provided on a straight-line
basis over a fifteen year estimated useful life of the asset and will commence
once the wafer facility becomes operational. Should the technology license be
revoked or made nonexclusive under the circumstances described above, a
resulting charge to income would be recorded to recognize impairment, if any, of
its value.
 
14. COMMITMENTS
 
  Facility Construction and Equipment
 
   
     At March 31, 1997, the Company is committed to leasing from a third party
real estate developer a wafer fabrication facility which is under construction
adjacent to its existing facility. The facility will be built in two phases. The
first and second phases are budgeted at approximately $40 million and $30
million, respectively. The Company's lease arrangement with the developer is
based on a total estimated cost to construct the facility. The term of this
operating lease is 15 years with the option to renew for two separate 10 year
periods. The developer will provide partial construction financing for the
facility. For the remainder of the estimated construction costs, the Company is
obligated to put up cash deposits with the developer to fund the construction.
    
 
     Costs to install a clean room at the facilities, estimated to cost between
$2.5 and $3 million including equipment, will be financed through a construction
loan which will convert to a 60 month lease upon completion of construction and
an equipment lease line. The Company has also obtained a lease commitment for an
additional $10 million of financing for equipment to up-fit the new facility.
The term of these capital leases will be 52 months. In connection with this
financing commitment, the Company has issued a warrant to purchase 41,322 shares
of its common stock at an exercise price of $9.00 per share to the equipment
financing company.
 
     The terms of these lease financing commitments are as follows:

15. SUBSEQUENT EVENTS
 
   
     In March 1997, the Company's Board of Directors adopted the following which
were approved by the shareholders in the April 10, 1997 shareholder meeting:
    
 
     - The 1997 Key Employees' Stock Option Plan which will permit the granting
      of both Incentive and Nonqualified Options. The aggregate shares granted
      under this plan will not exceed 1.3 million.
 
     - The Nonemployee Directors' Option Plan which will provide for reserving
      up to 200,000 shares of common stock for future option grants under this
      plan.
 
   
     - The Employee Stock Purchase Plan, which is intended to qualify under
      Section 423 of the Internal Revenue Code. The plan is intended to provide
      the opportunity for the Company's employees to purchase the Company's
      common stock based on terms and conditions allowed by Section 423. An
      aggregate of 500,000 shares of common stock will be reserved for offering
      under this plan.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Sections 55-8-50 through 55-8-58 of the North Carolina Business Corporation
Act contains specific provisions relating to indemnification of directors and
officers of North Carolina corporations. In general, such sections provide that
(i) a corporation must indemnify a director or officer who is wholly successful
in his defense of a proceeding to which he is a party because of his status as
such, unless limited by the articles of incorporation, and (ii) a corporation
may indemnify a director or officers if he is not wholly successful in such
defense, if it is determined as provided by statute that the director or officer
meets a certain standard of conduct, provided when a director or officer is
liable to the corporation or is adjudged liable on the basis that personal
benefit was improperly received by him, the corporation may not indemnify him. A
director or officer of a corporation who is a party to a proceeding may also
apply to the courts for indemnification, and the court may order indemnification
under certain circumstances set forth in the statute. A corporation may, in its
articles of incorporation or bylaws or by contract or resolution, provide
indemnification in addition to that provided by statute, subject to certain
conditions.
 
     The Registrant's bylaws provide for the indemnification of any director or
officer of the Registrant against liabilities and litigation expenses arising
out of his status as such, excluding (i) any liabilities or litigation expenses
relating to activities which were at the time taken known or believed by such
person to be clearly in conflict with the best interest of the Registrant and
(ii) that portion of any liabilities or litigation expenses with respect to
which such person is entitled to receive payment under any insurance policy.
 
     The Registrant's articles of incorporation provide for the elimination of
the personal liability of each director of the Registrant to the fullest extent
permitted by law.
 
     In connection with the Offering, the Registrant intends to obtain
directors' and officers' liability insurance, under which any controlling
person, director or officer of the Registrant will be insured or indemnified
against certain liabilities which he may incur to his capacity as such.
 
     Under the underwriting agreement to be entered into by the Registrant,
certain controlling persons, directors and officers of the Registrant may be
entitled to indemnification by underwriters who participate in the distribution
of securities covered by the Registration Statement against certain liabilities,
including liabilities under the Securities Act.
 
ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES.
 
     Since April 1, 1994, except as set forth below, no securities of the
Registrant have been sold by the Registrant without registration under the
Securities Act.
 
                                      II-1
<PAGE>   87
 
     On December 30, 1994 and January 24, 1995, the Registrant issued an
aggregate amount of 1,272,727 shares of Class B Convertible Preferred Stock to
certain individuals and entities, each, except one individual, believed to be an
accredited investor. In exchange for such shares, the Registrant received cash
in the aggregate amount of $3,500,000. The Registrant issued the securities in
reliance on the exemption from registration provided by Section 4(2) of the
Securities Act.
 
     On August 4, 1995, the Registrant issued to an investor, believed to be an
accredited investor, a subordinated note to evidence the borrowing of up to
$2,000,000. The note bore interest at a rate equal to the prime rate as reported
in the Wall Street Journal plus one percent. The note had a term of the shorter
of six months or the closing date of the sale and issuance of equity securities
by the Registrant with cash proceeds of at least $1,000,000. In connection with
the note, on August 7, 1995 and November 10, 1995, the Registrant borrowed
$1,000,000 and $500,000, respectively, from the investor and issued to the
investor warrants for the purchase of up to an aggregate amount of 54,546 and
27,272 shares of Common Stock, respectively, for a purchase price of $2.75 per
share. The Registrant issued the note and warrants in each case in reliance on
the exemption from registration provided by Section 4(2) of the Securities Act.
On November 22, 1995, in reliance on the exemption provided by Section 4(2) of
the Securities Act, the Registrant issued an aggregate amount of 178,071 shares
of Class C Convertible Preferred Stock to this investor in satisfaction of
$1,076,974 in principal and accrued interest owed under the note. Pursuant to
its terms, the warrant issued to this investor for the purchase of 27,272 shares
of Common Stock at $2.75 per share became on this date a warrant for the
purchase of 12,400 shares of Common Stock at $6.048 per share.
 
     In addition to the shares referred to in the foregoing paragraph, on
November 22, 1995, the Registrant issued an aggregate amount of 1,640,712 shares
of Class C Convertible Preferred Stock to certain individuals and entities, each
believed to be an accredited investor. In consideration for these shares, the
Registrant received cash in the amount of $9,923,084. The Registrant issued
these securities in reliance on the exemption from registration provided in
Section 4(2) of the Securities Act.
 
     On June 6, 1996, the Registrant issued 826,446 shares of Class C
Convertible Preferred Stock to an entity, believed to be an accredited investor,
in exchange for an aggregate consideration of $5,000,000 in cash. In
consideration of this investor's execution, delivery and performance of a
licence and technical assistance agreement, the Registrant also issued to the
investor 2,683,930 shares of Common Stock, which shares are subject to a
restricted stock agreement pursuant to which, among other things, the investor
granted to the president of the Registrant an irrevocable proxy to vote such
shares of Common Stock in favor of any proposal approved by the Registrant's
board of directors. The Registrant also issued to the investor a promissory note
pursuant to which the Registrant may borrow funds in an amount up to
$10,000,000. The note bears interest at the rate of 6% per annum and is payable
in a lump sum on June 6, 2003. The note is convertible, at the option of the
noteholder, into certain equity securities of the Registrant at the conversion
price of $9.00 per share, subject to adjustment. In the event of an offering of
Common Stock with gross proceeds to the Registrant of at least $15,000,000, the
noteholder is required (subject to compliance with applicable antitrust
requirements) to convert the note into Common Stock. The note was accompanied by
a warrant for the purchase of equity securities of the Registrant on terms and
conditions set forth in the note. The warrant may be exercised only to the
extent that the note is not converted; together, the two securities provide for
the purchase of up to an aggregate amount of 1,111,111 shares of equity
securities of the Registrant at a conversion price or exercise price, as the
case may be, of $9.00 per share. The Registrant also issued to the investor an
additional warrant to purchase up to 1,000,000 shares of Common Stock at an
exercise price of $10.00 per share. This warrant may be exercised only if
certain conditions are met. The Registrant issued the Common Stock, the note and
the warrants in each case in reliance on the exemptions from registration
provided by Section 4(2) of the Securities Act.
 
   
     Between May 2, 1992 and March 31, 1997, the Registrant granted options for
the purchase of an aggregate amount of 1,065,116 shares of Common Stock to
certain officers and employees of the Registrant pursuant to its 1992 Stock

     (b) Financial Statement Schedules
 
     The following financial statement schedule is included in Part II of this
Registration Statement:
 
   
Schedule II -- Valuation and Qualifying Accounts, Years Ended March 31, 1997,
               March 31, 1996 and 1995.
    
 
          All other schedules are omitted because they are not required, they
     are not applicable or the information is already included in the financial
     statements or notes thereto.
 
ITEM 17.  UNDERTAKINGS.
 
     1. The undersigned registrant hereby undertakes that:
 
          (a) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this registration statement in reliance upon Rule 430A and contained in
     the form of prospectus filed by the registrant pursuant to Rule 424(b)(1)
     or (4) or 497(h) under the Securities Act shall be deemed to be part of
     this registration statement as of the time it was declared effective.
 
          (b) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.
 
     2. The undersigned registrant hereby undertakes to provide to the
underwriter at the closing specified in the underwriting agreements certificates
in such denominations and registered in such names as required by the
underwriter to permit prompt delivery to each purchaser.
 
     3. Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question of whether such indemnification by it is against
public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

May 2, 1997


RF Micro Devices, Inc.
7625 Thorndike Road
Greensboro, North Carolina 27409-9421

         Re:  Registration Statement on Form S-1
              Relating to 2,917,550 Shares of Common Stock
              (File No. 333-22625)

Gentlemen:

         We are acting as counsel to RF Micro Devices, Inc. (the "Company") in
connection with the registration under the Securities Act of 1933, as amended
(the "Act"), of 2,917,550 shares of the Company's common stock, no par value
(the "Common Stock"), consisting of 2,880,550 shares of Common Stock to be sold
by the Company (the "Primary Shares") and 37,000 shares of Common Stock to be
sold by certain shareholders of the Company (the "Secondary Shares"). We have
assisted the Company in the preparation of a Registration Statement on Form S-1
relating to the Primary Shares and the Secondary Shares, filed with the
Securities and Exchange Commission (the "Commission") on February 28, 1997,
Amendment No. 1 thereto, filed with the Commission on April 8, 1997, and
Amendment No. 2 thereto, filed with the Commission on May 2, 1997 (the
"Registration Statement"). We are providing this opinion pursuant to the
requirements of Item 16(a) of Form S-1 and Item 601(b)(5) of Regulation S-K
under the Act.

         We have reviewed and are familiar with the Registration Statement, the
records relating to the organization of the Company, including its articles of
incorporation and bylaws and all amendments thereto, and all records of all
proceedings taken by the Board of Directors and shareholders of the Company
pertinent to the rendering of this opinion.

         Based on the foregoing, it is our opinion that the Secondary Shares
are, and, when sold as described in the Registration Statement, the Primary
Shares will be, duly authorized, validly issued, fully paid and nonassessable.

         We hereby consent to the filing of this opinion with the Commission as
Exhibit 5 to the Registration Statement and to the use of our name in the
Registration Statement under the caption "Legal Matters" in the prospectus
included as a part thereof. In giving this consent, we do not admit that we are
within the category of persons whose consent is required by Section 7 of the Act
or other rules and regulations of the Commission thereunder.


                                     Very truly yours,

                                     WOMBLE CARLYLE SANDRIDGE & RICE,
                                     A Professional Limited Liability Company

maintenance of patent applications and patents included in the Patent Rights,
and shall have sole financial responsibility for patent acquisition or
maintenance of the Patent Rights to the extent it elects, in its sole
discretion, to pursue the same.  From time to time at the reasonable request of
Licensee, Licensor shall furnish Licensee with a written report setting forth
in reasonable detail the identity and status of each patent and patent
application included in the Patent Rights.  In the event Licensor determines
that it no longer deems it necessary or desirable to prosecute a patent
application or maintain a patent included in the Patent Rights in any country,
Licensor shall notify Licensee not less than thirty (30) days prior to the
abandonment of the patent application or the final due date for the payment of
the maintenance fee.  In such event, Licensee may obtain an assignment of the
patent application or patent by notifying Licensor and providing it with
appropriate assignment documents in a form ready to be executed by it, and
thereafter Licensee shall own the same and shall have the right to (and the
sole financial responsibility for) management and control of the prosecution
and maintenance of such patent applications and patents.  Any assignment of any
patent or patent application pursuant to this Section 2.9 shall include a
royalty-free, fully paid up non-exclusive license to Licensor under such patent
or application to design, develop, manufacture, have manufactured, use, test,
sell, market, service, and repair any products outside of Licensed Field.

         2.10    ENFORCEMENT OF PATENT RIGHTS:

                 2.10.1  If either party hereto learns at any time of any
infringement or threatened infringement by any other person of any enforceable
Patent Rights owned by or licensed to the other party after the Effective Date,
that party shall give notice of that infringement or threatened infringement to
the other party.  The parties shall then consult together as to the best course
of action to pursue in response to such potential infringement, but neither
party shall be obligated to institute legal action at its own expense.  A good
faith failure by one party to provide such notice to the other party shall not
be deemed a breach of this Agreement and shall not give rise to a right of
action by other party.

                 2.10.2  In the event that the parties do not reach an
agreement as contemplated by Section 2.10.1 hereof as to the best course of
action to pursue with respect to a potential infringement (i) Licensor shall
have the right, but not the obligation, to institute legal action, through
counsel of its own choosing and at its sole expense, to restrain any
infringement or threatened infringement, or to recover damages therefor, of its
enforceable Patent Rights, and (ii) Licensee shall have the right, but not the
obligation, to institute legal action, through counsel of its own choosing and
at its sole expense, to restrain any infringement or threatened infringement,
or to recover damages therefor, of its enforceable Patent Rights in the
Licensed Field.  The party that bears the expenses of pursuing legal action
against a third party infringer shall be entitled to any damages, lost profits
or other monies recovered by judgment, decree, settlement, arbitration or
otherwise, resulting from such legal action.

                 2.10.3  In the event that one party elects to institute legal
action against a third party infringer, the other party shall fully cooperate
in the prosecution of such action including joining as a party in suit when
necessary to acquire standing to institute legal action pursuant to this
Section 2.10; provided, however, that such other party shall be reimbursed for
all reasonable out-of-pocket expenses incurred in providing such cooperation
including its reasonable legal fees and expenses.  The electing party shall
reimburse the other party for all such expenses within thirty (30) days after
its receipt of an invoice from the other party that describes such expenses in
reasonable detail, with supporting documentation as appropriate.

any Order (i) for any Products not listed in Exhibit 1A hereto or revisions

hereof, and at the request of Buyer, TRW develops a modified smaller chip
design for any Products listed in Exhibit 1A, which allows a larger number of

aggregate shall continue for more than one hundred eighty (180) days and the
parties have not agreed upon a revised basis for performing the Order at the
end of such delays, then either party, upon thirty (30) days written notice,
may terminate such Order without liability.

         9.2     TRW DELAYS:  If at any time TRW discovers that it is unable
(whether for reasons set out in Section 9.1 or otherwise) to deliver any
Products to Buyer on the scheduled delivery date, TRW shall give Buyer written
notice within two (2) days of such discovery, which notice shall specify the
delivery date on which TRW shall be able to deliver such Products to Buyer.  If
the delivery date proposed by TRW is more than forty-five (45) days after the
scheduled delivery date, Buyer shall have the right, without liability, to
cancel (in whole or in part) its Order for such Products, by giving TRW notice
of cancellation within ten (10) days of receipt of TRW's notification of delay.

         9.3     TERMINATION:  If the delays resulting from any of the causes
stated in Section 9.2 extend in the aggregate for more than one hundred eighty
(180) days on any Order and the parties have not agreed upon a revised basis
for continuing work on such Order at the end of such delays, including
adjustment of the price, then either party, upon thirty (30) days written
notice, may terminate this Agreement with respect to the unexecuted portion of
the work, whereupon Buyer shall pay TRW its termination charges as provided in
Section 9.4 below.

         9.4     TERMINATION CHARGES:  In the event of termination of an Order
under this Agreement for any reason, TRW shall promptly submit to Buyer a
detailed written statement and supporting documentation (such as TRW incurred
cost report and vendor invoices) of TRW's total costs incurred in the
performance of work under such Order and total cost resulting from such
termination as determined in accordance with TRW's standard accounting
practices and, if requested by Buyer, verified to Buyer by TRW's independent
auditors at Buyer's expense (hereinafter referred to as the "Total Verified
Termination Cost").

         The Total Verified Termination Cost shall include the following:

                 (1)      One hundred percent (100%) of the total termination
                          costs incurred by TRW, including but not limited to
                          any committed and/or termination costs incurred by
                          TRW's suppliers and vendors, less the amounts
                          previously paid by Buyer pursuant to such Order;

                 (2)      The price of any completed Products pursuant to
                          Exhibit 1B; and

                 (3)      TRW's costs incurred in performing uncompleted work,
                          plus profit in the amount of fifteen percent (15%) of
                          such costs.





                                       5

The Total Verified Termination Cost shall be paid by Buyer within thirty (30)
days after receipt of TRW's invoice therefor.

                           TRANSFERS AND ASSIGNMENTS

         Buyer may assign all or part of its rights and delegate all or part of
its duties described in this Agreement by giving written notice thereof to TRW.
Since this Agreement requires the performance of personal services by TRW, TRW
may not assign any right or delegate any duty described in this Agreement
without Buyer's prior written approval, which approval shall not be
unreasonably withheld, provided that this shall not affect TRW's right to
assign without Buyer's consent, either absolutely or by way of charge, any
moneys due or to become due to it or which may become payable to it under this
Agreement.


                                   ARTICLE 11
                                    DEFAULT

         11.1    EVENT OF DEFAULT:  An Event of Default on the part of either
party shall exist under this Agreement if:

                 (a)      Such party fails to pay the other party any amount
         required to be paid hereunder when due and payable hereunder; or

                 (b)      Such party fails to perform its minimum purchase or
         supply obligations (as the case may be hereunder) specified in Section
         2.2 hereof during any calendar year during the term hereof, or
         otherwise fails to perform any other material obligation required to
         be performed by it under any provision of this Agreement (except the
         payment of money) within thirty (30) days after the time specified or
         within thirty (30) days after notice from the other party that such
         performance has become due; provided, however, a party shall have no
         right to terminate this Agreement for the other party's default so
         long as corrective action is being diligently pursued by the
         defaulting party in a manner that demonstrates that such party's
         obligations hereunder shall be completed in sufficient time to allow
         the non-defaulting party not to be prejudiced thereby.

         11.2    REMEDIES AVAILABLE FOR DEFAULT:  Subject to other provisions
hereof which expressly limit the remedies available hereunder, if an Event of
Default as defined in Section 11.1 exists on the part of either party, then the
other party may terminate this Agreement upon giving written notice of
termination and pursue any other remedies available at law or in equity.

construed as a warranty or representation by TRW that the manufacture, sale,
lease, use or other disposition of Products shall be free from infringement of
patents, utility models, design patents, maskwork rights, copyrights, trade
secrets and/or other legal rights of third parties.

         12.2    LIMITATION OF LIABILITY:  With the exception of Buyer's
obligation to pay invoices for deliveries of Products hereunder, the total
aggregate liability of a party under this Agreement and all Orders placed
hereunder on any claim, whether in contract, tort (including sole or concurrent
negligence), or otherwise, arising out of, connected with, or resulting from
the manufacture, supply, delivery, resale, repair, replacement, or use of
Products

shall not exceed one hundred thousand dollars ($100,000).

         12.3    DAMAGES:  In no event shall either party be liable for any
special, indirect, incidental or consequential damages, however caused, whether
by such party's sole or concurrent negligence or otherwise, including but not
limited to costs and expenses incurred in connection with labor, overhead,
transportation, installation, or removal of Products or substitute facilities
or supply sources.

to time, and at any time during the term hereof, request a change, as defined
in Section 14.1, in this Agreement.  (The party requesting the change is

purchased items not manufactured by TRW may be made by TRW with the consent of
Buyer, which consent may not be unreasonably withheld.

         documents, ideas, know-how and other information supplied by one party
         to another (whether disclosed orally, or in documentary form, by
         demonstration or otherwise) for the purpose of achieving the
         objectives of this Agreement.

                 (b)      "Proper Use" shall mean use of the Proprietary
         Information solely by the recipient for the objectives of this
         Agreement.

         15.2    NONDISCLOSURE.  All Proprietary Information furnished shall
remain the property of the disclosing party and shall be treated by the
recipient in strict confidence, shall not be used except for Proper Use, shall
be disclosed by the recipient only to persons within the recipient's company
(including companies directly or indirectly more than fifty percent (50%) owned
or controlled by the recipient) who are directly concerned in the Proper Use,
and shall not be disclosed to consultants or by the recipient to any other
party without the disclosing party's prior written consent, except for
Proprietary Information which the recipient can show was:

                 (a)      In the public domain at the time it was disclosed; or

                 (b)      Known to the recipient without restriction at the
         time of receipt; or

                 (c)      Published or becomes available to others without
         restriction through no act or failure to act on the part of the
         recipient; or

                 (d)      Disclosed inadvertently despite the exercise of the
         same degree of care as the recipient takes to preserve and safeguard
         its own proprietary information; or

                 (e)      Known to the recipient from a source other than the
         disclosing party without breach of this Agreement by the recipient; or

                 (f)      Subsequently designated by the disclosing party in
         writing as no longer proprietary; or
 
                 (g)      Independently developed by the recipient; or

                 (h)      Disclosed after five (5) years from the date of
         delivery by the disclosing party to the recipient, which five (5) year
         period shall survive the termination of this Agreement.

If any portion of Proprietary Information falls within any one of these
exceptions, the remainder shall continue to be subject to the foregoing
prohibitions and restrictions.  The recipient of Proprietary Information shall

form by one party to the other party shall be marked with the legend:

                 "RFMD PROPRIETARY INFORMATION"
         or -    "TRW PROPRIETARY INFORMATION"

as the case may be, or an equivalent conspicuous legend.  No sheet or page of
any written material shall be so labeled which is not, in good faith, believed
by the disclosing party to contain Proprietary Information.  A recipient of
Proprietary Information hereunder shall have no obligation with respect to any
portion of any written material which is not so labeled or any information
received orally unless it is identified as proprietary and a written summary of
such oral communication, specifically identifying the items of Proprietary
Information, is furnished to the recipient within thirty (30) days of such
disclosure.

                 The individuals identified below are the only persons
authorized to receive Proprietary Information on behalf of the parties:

         For Buyer:       Mr. Powell Seymour

         15.4    COMPENSATION.  The parties shall not be obligated to
compensate each other for the transfer of any Proprietary Information under

granted under any patent, trademark or copyrights with respect to any
Proprietary Information.

confidentiality set forth in this Article 15 shall survive termination or
completion of this Agreement.

         15.6    INVENTIONS AND PATENTS.  Inventions conceived solely by
employees of a party under this Agreement shall belong exclusively to such
party.  Inventions conceived jointly by the parties in the course of work
called for in this Agreement shall be subject to the further agreement of the
parties.  Except as expressly set forth in this Agreement, nothing contained in
this Agreement shall be deemed, by implication, estoppel or otherwise, to grant
any party any right or license in respect of any patents, inventions,
Proprietary Information or other technical data at any time owned by the party
hereto.  Irrespective of in whose name(s) patent applications are filed, any
party which is a co-inventor of an invention shall be entitled to a
non-exclusive, royalty-free, transferable license in any patent(s) issued with
respect thereto.  The understandings set forth in this Section 15.6 are subject
to modification as may be required by applicable government regulations.
Notwithstanding the above, each party shall have a non-exclusive, royalty-free,
non- transferable, worldwide right and license under any inventions, patents,
Proprietary Information and technical data owned by the other party and used in
Products made under this Agreement, but only to the extent such licenses are
required for the limited purpose of enabling a party to perform its obligations
under this Agreement or to enable Buyer to sell products incorporating Products
made by TRW under this Agreement.

         15.7    OWNERSHIP OF MASKSETS.   Buyer shall retain sole ownership of

Masksets to Buyer and after expiration of such two (2) year storage period may
destroy or dispose of such Masksets upon giving Buyer ten (10) days prior
written notice thereof.

         15.8    OWNERSHIP OF MMIC DESIGNS.  Buyer shall retain sole ownership
rights to its designs for





                                       9
<PAGE>   10

monolithic microwave integrated circuit ("MIMIC") designs.  TRW shall retain

exercise of one right or remedy shall not be deemed a waiver of any other right
or remedy.

         16.3    MODIFICATION AND WAIVER:  No cancellation, modification,
amendment, deletion, addition, or other change in the Agreement or any
provision hereof, or waiver of any right or remedy herein provided, shall be
effective for any purpose unless specifically set forth in a writing signed by
the party to be bound thereby. No waiver of any right or remedy in respect of
any occurrence or event on one occasion shall be deemed a waiver of such right
or remedy in respect of such occurrence or event on any other occasion.

agreement of the parties and supersedes all other agreements, oral or written,
