This Amendment No. 9 on Schedule 13D amends the beneficial ownership statement
initially filed on February 12, 1998 on Schedule 13G, as amended by Amendment
No. 1 on Schedule 13D filed on June 29, 1998, Amendment No. 2 on Schedule 13D
filed on September 18, 1998, Amendment No. 3 on Schedule 13D filed on February

5 on Schedule 13D filed on June 1, 1999, Amendment No. 6 on Schedule 13D filed
on June 9, 1999, Amendment No. 7 on Schedule 13D filed on October 5, 1999 and
Amendment No. 8 on Schedule 13D filed on October 12, 1999 (collectively, the
"Schedule 13D"), pursuant to Rule 13d-1(d) under the Securities Exchange Act of
1934, as amended, by TRW Inc., an Ohio corporation ("TRW"). This statement is
being filed to reflect the execution of a new License Agreement and a
Cooperation Agreement by and between TRW and RF Micro Devices, Inc. ("RFMD") on
November 15, 1999. Unless otherwise defined herein, all capitalized terms used
herein shall have the respective meanings given such terms in the Schedule 13D.
Except as modified herein, there have been no other changes in the information
previously reported in the Schedule 13D.

Item 4. Purpose of Transaction.

Item 4 is amended by adding the following paragraphs at the conclusion of the
fourth paragraph thereof:

On November 15, 1999, TRW and RFMD expanded their strategic relationship through
the execution of a new License Agreement (the "License Agreement"), pursuant to
which TRW has expanded the license granted RFMD in 1996 to permit RFMD to use
TRW's patented gallium arsenide heterojunction bipolar transistor ("GaAs HBT")
technology to manufacture products for commercial coaxial and other non-fiber
wire applications, including the broadband wired market. On this same date, TRW
and RFMD also entered into a Cooperation Agreement (the "Cooperation Agreement")
pursuant to which, among other things, the parties agreed to negotiate in good
faith with each other regarding additional licensing arrangements and an
extended GaAs HBT supply agreement, and TRW committed to maintain stock
ownership of at least 7.94 million shares of RFMD Common Stock, no par value
("RFMD Common Stock"), until May 1, 2001. In exchange for granting the expanded
license to RFMD and entering into the Cooperation Agreement, RFMD granted TRW
two warrants (the "Warrants") to purchase, in the aggregate, 750,000 shares of
RFMD Common Stock. The Warrants will become exercisable in 2001 and are subject,
in part, to the achievement of certain sales milestones by RFMD. The Warrants
will be priced at a specified discount to the average closing price per share of
RFMD Common Stock for the ten trading days immediately preceding December 31,
2000. A copy of the License Agreement, the Cooperation Agreement and the
Warrants are filed as exhibits to this Schedule 13D and are incorporated herein
by reference.

Since January 1999, TRW has reduced its ownership in RFMD to approximately 20
percent, raising proceeds to pay off debt incurred to finance its acquisition of
LucasVarity. Subject to market conditions, TRW intends to reduce its holdings in
RFMD further to continue its debt reduction efforts, but, as noted above, has
agreed to hold a minimum of 7.94 million shares of RFMD Common Stock until May
1, 2001.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to
Securities of the Issuer.

Item 6 is amended by adding the following paragraph at the conclusion thereof:

As noted above, pursuant to the Cooperation Agreement entered into between TRW
and RFMD on November 15, 1999, TRW has agreed to maintain stock ownership of at
least 7.94 million shares of RFMD Common Stock until May 1, 2001. Further, the
Warrants provide that TRW may not assign, sell or otherwise transfer, dispose
of, make any short sale of, pledge, hypothecate, grant any option for the
purpose of, or enter into any hedging, synthetic sale or similar transaction
with the same economic effect as a sale of, the Warrants or any of TRW's rights
under the Warrants, except to an affiliate of TRW or as a result of a merger or
consolidation of TRW into another entity.

Item 7. Material to be Filed as Exhibits.

Item 7 is amended by adding the following exhibits thereto:

TRW/RF Micro Devices
License Agreement
November 15, 1999


                  2.2.1 Licensor shall deliver a notice to Licensee stating its
         bona fide intention to grant rights and/or licensees to a third party
         for technologies applicable to the Licensed Products, and identify the
         specific technology it desires to license (the "Offered Technology")
         and the terms and conditions by which it proposes to license the
         Offered Technology.

                  2.2.2 Within forty-five (45) days after the date of such
         notice, Licensee shall inform Licensor whether or not it is willing to
         license the Offered Technology upon the same terms and conditions which
         Licensor proposes to license the Offered Technology to the third party.
         If Licensor has not received Licensee's decision by the end of the
         forty-five (45) day period, it will be deemed that Licensee has decided
         not to license the Offered Technology.

                  2.2.3 If Licensee does not elect to license the Offered
         Technology in accordance with Section 2.2.2, Licensor may license the
         Offered Technology to any third party upon terms which in their
         entirety are no more favorable to the prospective third party than
         those specified to Licensee, provided that the license is consummated
         within ninety (90) days of the date of the notice to Licensee. Licensor
         may, at its discretion, alter the final terms of the license to the
         third party from those notified to Licensee such that, though
         individual terms may be more favorable to the third party, the overall
         license terms and conditions are in their entirety no more favorable to
         the third party than those notified. If the final terms and conditions
         are, in their entirety, considered to be more favorable to the third
         party than those notified to Licensee, then Licensor must offer those
         terms to Licensee in accordance with Section 2.2.2, and Licensee shall
         have forty-five (45) days to elect to license the Offered Technology.

                  2.2.4 All obligations to grant licenses to future TRW
         technologies under this Section 2.2 shall terminate ten (10) years from
         the Effective Date.

         licenses proposed to be granted by Licensor to its affiliated
         companies.

         2.3 EXCLUSION: Except as otherwise provided in this Agreement, the
license and rights granted hereunder shall not be interpreted as granting or
implying the grant of rights in any other invention or technical information of
either party.

         2.4 MARKINGS: To the extent practical, Licensee shall provide on any
Licensed Product or component parts thereof manufactured, used or sold utilizing
any of the rights or licenses granted under this Agreement, or on the packaging
or data sheets related thereto so long as the marking is in accordance with
applicable marking provisions of United States or foreign patent laws, a legible
notice that such Licensed Product or component part is manufactured under a
license granted by Licensor. Licensee shall submit to Licensor prior to marking
any Licensed Product or component part thereof the full copy of such proposed
marking for written approval by Licensor, which approval will not be
unreasonably withheld and will be deemed given unless Licensor responds to the
contrary within ten (10) business days of such submission. No rights are granted
hereunder by either party to the other regarding their respective trade names or
trademarks.

         2.5 LICENSOR RESERVATIONS: Licensor reserves unto itself the rights to
utilize Existing TRW GaAs HBT Patent Rights, Future TRW GaAs HBT Patent Rights,
and HBT Technical Information to manufacture, have manufactured, use, test,
sell, service, and repair Licensed Products in the Licensed Field and to grant
sublicenses to other parties to do so, subject to the provisions of Section 2.2.

                  2.7.1 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.

                  2.7.2 In the event that the parties do not reach an agreement
         as contemplated by Section 2.7.1 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.

                  2.7.3 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 2.7; 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.

including any inventions, shall be promptly made known to Licensor in the form

to such modifications, improvements or inventions. If, in countries selected by
Licensor, Licensee decides it shall not file applications for, or maintain
patents upon, Licensee's modifications, improvements or inventions, then

patents shall be and become its property, provided Licensee shall continue to

This Cooperation Agreement (the "Agreement") is entered into as of this 15th day
of November, 1999, by and between TRW Inc. ("TRW") and RF Micro Devices, Inc.
("RFMD").

cooperative actions;

NOW THEREFORE, the parties hereto agree as follows:

strategic relationship as evidenced in the 1996 Agreement and the 1999
Agreement. More specifically, the parties agree to continue to exchange
technical information with each other concerning the Licensed Products in the
Licensed Fields (as such terms are defined in the 1996 Agreement and the 1999
Agreement). Further, during the term of this Agreement, the parties shall on a
regular basis consult with each other concerning new technologies which are
developed by either party and which could be reasonably viewed as applicable to
other party's markets.

2. LICENSE EXPANSION. The parties agree that, during the term of this Agreement,
TRW, upon the request of RFMD, shall enter into good faith negotiations with
RFMD concerning the further expansion of the licenses granted in the 1996
Agreement and the 1999 Agreement beyond the respective Licensed Fields for the
respective Licensed Products (as defined in the 1996 Agreement and the 1999
Agreement). Further, TRW, upon the request of RFMD, shall enter into discussions
with RFMD concerning the possible licensing of new or existing TRW technologies
that may be applicable to RFMD's markets. Neither of the parties is obligated to
enter into any new or expanded license, and the terms of any such new or
expanded license shall be subject to the mutual agreement of the parties.

3. SUPPLY AGREEMENT AMENDMENT. Upon the request of TRW, RFMD agrees to enter
into good faith negotiations with TRW concerning the extension of the Supply
Agreement, dated as of June 6, 1996, as amended (the "Supply Agreement"),

amendment of the Supply Agreement, and the terms of any such amendment to the
Supply Agreement shall be subject to the mutual agreement of the parties.

4. STOCK OWNERSHIP COMMITMENT. In conjunction with the announcement referred to
in paragraph 6 hereof, TRW shall publicly state that until May 1, 2001 it
(directly and/or indirectly through its affiliated entities) will continue to
beneficially hold at least 7,941,161 shares of RFMD common stock (such number to
be adjusted for stock divisions, stock combinations, stock recapitalizations and
stock reclassifications and stock dividends). Further, TRW agrees that it shall
beneficially hold 7,941,161 shares of RFMD common stock (directly and/or
indirectly through its affiliated entities) (such number to be adjusted for
stock divisions, stock combinations, stock recapitalizations and stock
reclassifications and stock dividends) until May 1, 2001 and shall not, at any
time prior to May 1, 2001, sell, assign or otherwise transfer, dispose of, grant
any option to purchase, make any short sale of or enter into any hedging,
synthetic sale or similar transaction with the same economic effect as a sale
that would have the effect of causing its RFMD common stock ownership to fall
below such number of shares (as may be adjusted), except in conjunction with a
transaction involving a Change in Control of RFMD (as such term is defined in
paragraph 1(b) of Warrant 99-2 referred to in paragraph 5 hereof).

5. WARRANT ISSUANCE. In consideration of TRW executing the 1999 License and this
Agreement, RFMD shall issue to TRW contemporaneously herewith two warrants to
purchase an aggregate of 750,000 shares of RFMD common stock on the terms

         NEITHER THIS WARRANT NOR THE SECURITIES ISSUABLE UPON EXERCISE
        HEREOF HAS BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
          AMENDED (THE "ACT"), OR THE SECURITIES LAWS OF ANY STATE AND
            NEITHER THIS WARRANT NOR SUCH SECURITIES MAY BE SOLD OR
              OTHERWISE TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE
         REGISTRATION STATEMENT UNDER SUCH ACT AND LAWS UNLESS RF MICRO
           DEVICES, INC. RECEIVES AN OPINION OF COUNSEL, WHICH MAY BE
        HOLDER'S IN-HOUSE COUNSEL, REASONABLY ACCEPTABLE TO IT THAT SUCH
           REGISTRATION IS NOT REQUIRED. TRANSFER OF THIS WARRANT IS
                         RESTRICTED. SEE PARAGRAPH 11.


       250,000 Shares                                     WARRANT NO. 99-1

                             RF MICRO DEVICES, INC.

                          A North Carolina Corporation

                             (Void after 5:00 p.m.,
                     Washington D.C. Time, on June 30, 2001)

                  THIS CERTIFIES THAT, for value received, TRW Inc. (the
"Holder") is entitled at any time after December 31, 2000 and at any time before
5:00 p.m. Washington D.C. time on June 30, 2001 (the "Expiration Time") to
purchase up to 250,000 (two hundred fifty thousand) shares (the "RFMD Shares")
of common stock, no par value (the "Common Shares"), of RF Micro Devices, Inc.
(the "Company") at the price per RFMD Share as determined in paragraph 1 of this
Warrant, subject to adjustment as provided in paragraph 5 of this Warrant (that
price, as it may be adjusted from time to time, being referred to as the
"Warrant Price").

                  1. The Warrant Price shall be the average of the Closing
Prices of the Common Shares during the ten (10) Trading Days immediately
preceding December 31, 2000 (the "Pricing Period") multiplied by 0.75. The
Closing Price for each day shall be the reported last sales price regular way
or, in case no such reported sale takes place on


<PAGE>   2


such day, the average of the reported closing bid and asked prices regular way,
in either case on the New York Stock Exchange or, if the Common Shares are not
listed or admitted to trading on such Exchange, on the principal national
securities exchange on which the Common Shares are listed or admitted to trading
(based on the aggregate dollar value of all securities listed or admitted to
trading) or, if not listed or admitted to trading on any national securities
exchange, on the NASDAQ National Market System or, if the Common Shares are not
listed or admitted to trading on any national securities exchange or quoted on
the NASDAQ National Market System, the average of the closing bid and asked
prices in the over-the-counter market as furnished by any New York Stock
Exchange member firm selected from time to time by the Company for that purpose.
The Closing Prices during the Pricing Period shall be adjusted to take into
account any stock divisions, stock combinations, stock recapitalizations or
reclassifications, stock dividends and the like in order that the Closing Prices
during the entire Pricing Period shall have the same reference point as the
Closing Price immediately prior to December 31, 2000. The average of the Closing
Prices shall be a simple average and shall not be weighted according to trading
volume or any other manner. "Trading Day" shall mean a day on which the national
securities exchange or the NASDAQ National Market System used to determine the
Closing Price is open for the transaction of business or the reporting of trades
or, if the Closing Price is not so determined, a day on which the New York Stock
Exchange is open for the transaction of business.

                  2. To exercise this Warrant, this Warrant must be surrendered
prior to the Expiration Time at the office of the Company at 7625 Thorndike
Road, Greensboro, North Carolina 27409 (or such other address as the Company may
specify in writing to


                                      -2-
<PAGE>   3


the Holder of this Warrant at least ten days before this Warrant is exercised)
with the attached Notice of Exercise duly completed and executed, accompanied by
evidence of a wire transfer of immediately available funds to the Company's
money market account #___________ with Silicon Valley Bank, Santa Clara,
California, ABA Routing #_________ (or such other account as the Company may
specify in writing to the Holder of this Warrant at least ten days before this
Warrant is exercised) in full payment of the purchase price of the RFMD Shares
with respect to which this Warrant is exercised. This Warrant may be exercised
in whole or in part as to any whole number of RFMD Shares. If this Warrant is
exercised in part, upon surrender of this Warrant for exercise, the Company will
issue to the Holder a new Warrant to purchase the remaining number of RFMD
Shares which may be purchased upon exercise of this Warrant (before taking
account of adjustments by reason of paragraphs 5, 6 and 7) and the number of
RFMD Shares with respect to which it is exercised (before taking account of
adjustments by reason of paragraphs 5, 6 and 7). The new Warrant will bear the
same date as this Warrant and will be identical to this Warrant in all respects,
except as to the number of RFMD Shares as to which it may be exercised.

                  3. The RFMD Shares as to which this Warrant is exercised will
be deemed to be issued when this Warrant is exercised. Holder agrees that prior
to the exercise of this Warrant, it will comply with the provisions of the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act")
as in effect from time to time. If action is taken by the Federal Trade
Commission or the United States Department of Justice to enjoin Holder's
exercise of this Warrant, the Company agrees reasonably to cooperate with Holder
to contest such enjoinment at the expense of this Holder. A certificate
representing the RFMD Shares will be issued to the Holder of this

                                      -3-
<PAGE>   4

Warrant promptly after it is exercised. The certificate may bear a legend to the
effect that the RFMD Shares it represents have not been registered under the
Securities Act of 1933, as amended (the "Act"), or any applicable state
securities laws, and may only be transferred in a transaction registered under
the Act or such laws or exempt from the registration requirements of the Act or
such laws. In addition, any other legend required by any other agreement between
the Company and Holder may be included on the certificate or certificates for
such RFMD Shares.

                  4. This Warrant will expire, and the right to purchase the
RFMD Shares by exercise of this Warrant will terminate, at the Expiration Time;
provided, however, that if Holder has complied with the filing provisions of the
HSR Act at least thirty days prior to the Expiration Time, but the waiting
period imposed by the HSR Act has not terminated or lapsed, then the Expiration
Time will be extended until ten days after such termination or lapse. After that
time this Warrant will be void.

                  5. The Warrant Price will be subject to adjustment from time
to time as follows:


                      (a) If, at any time after December 31, 2000, the Company
     (i) pays a dividend on its Common Stock in Common Stock, (ii) splits or
     subdivides its outstanding shares of Common Stock, or (iii) combines its
     outstanding shares of Common Stock into a smaller number of shares, the
     Warrant Price in effect immediately prior to each of those events will be
     adjusted proportionately so that the adjusted Warrant Price will bear the
     same relation to the Warrant Price in effect immediately prior to the event
     as the total number of shares of Common Stock outstanding immediately prior
     to the event will bear to the total number of shares of Common Stock
     outstanding immediately after the event.


                                      -4-
<PAGE>   5



                      (b) An adjustment made pursuant to subparagraph (a) of
     this paragraph will become effective immediately after the corresponding
     record date in the case of a dividend and immediately after the effective
     date in the case of a subdivision or combination.

                  No adjustment of the Warrant Price will be made if the amount
of such adjustment would be less than 2% of the Warrant Price, but any such
adjustment that would otherwise be required to be made and has not previously
been made will be carried forward and be made at the time of and together with
the next subsequent adjustment which, together with all adjustments so carried
forward, amount in the aggregate to 2% or more of the Warrant Price. As used in
this Warrant, "Common Stock" includes any class of the Company's capital stock,
now or hereafter authorized, having the right to participate in the distribution
of either earnings or assets of the Company without limitation as to amount or
percentage. At no time will the Warrant Price be less than $.01 per share.

                  6. (a) In case the Company shall at any time or from time to
time (i) subdivide its outstanding shares of Common Stock into a greater number
of shares or (ii) combine its outstanding shares of Common Stock into a smaller
number of shares, then the number of RFMD Shares, in effect immediately prior to
such event, shall be porportionately increased in the case of a subdivision and
proportionately decreased in the case of combination. Any adjustment under this
subparagraph 6(a) shall become effective at the close of business on the date
the subdivision or combination becomes effective.

                     (b) In case the Company shall at any time or from time to
time makes, or fixes a record date for the determination of holders of the
Common Stock

                                      -5-



<PAGE>   6

entitled to receive, a dividend or other distribution payable in additional
shares of Common Stock, then and in such event the number of RFMD Shares then in
effect shall be increased as of the time of such issuance or, in the event such
record date is fixed, as of the close of business on such record date, by
multiplying the number of RFMD Shares then in effect by a fraction (x) the
denominator of which is the total number of shares of the Common Stock issued
and outstanding immediately prior to the time of such issuance or the close of
business on such record date, and (y) the numerator of which shall be the total
number of shares of the Common Stock issued and outstanding immediately prior to
the time of such issuance or the close of business on such record date plus the
number of shares of the Common Stock issuable in payment of such dividend or
distribution; provided, however, that if such record date is fixed and such
dividend is not fully paid or if such distribution is not fully made on the date
fixed therefor, the number of RFMD Shares shall be recomputed accordingly based
on the number of additional shares of Common Stock actually issued as of the
close of business on the date originally fixed for the payment of such dividend
or the making of such distribution and thereafter the number of RFMD Shares
shall be adjusted pursuant to this subparagraph 6(b) at the time of actual
payment of any additional dividends or distributions of Common Stock.

                      (c) In case the Company shall issue rights or warrants to
all or substantially all holders of its Common Stock entitling them to subscribe
for or purchase shares of Common Stock at a price per share less than the Fair
Market Value (as hereinafter defined) per share of the Common Stock on the date
fixed for the determination of shareholders entitled to receive such rights or
warrants, the number of RFMD Shares, in effect at the opening of business on the
day following the date fixed for such determination, shall be increased by
multiplying such number of RFMD Shares by a fraction of which the denominator
shall be the number of shares of Common Stock outstanding at the close of
business on the date fixed for such determination plus the

                                      -6-




<PAGE>   7

number of shares of Common Stock which the aggregate of the offering price of
the total number of shares of Common Stock so offered for subscription or
purchase would purchase at such Fair Market Value, and the numerator shall be
the number of shares of Common Stock outstanding at the close of business on the
date fixed for such determination plus the number of shares of Common Stock so
offered for subscription or purchase, such adjustment to become effective
immediately after the opening of business on the day following the date fixed
for such determination; provided, however, in the event that all the shares of
Common Stock offered for subscription or purchase are not delivered upon the
exercise of such rights or warrants, the number of RFMD Shares shall be
readjusted to the number of RFMD Shares that would have been in effect had the
numerator and the denominator of the foregoing fraction and the resulting
adjustment been made based upon the number of shares of Common Stock actually
delivered upon the number of shares of Common Stock offered for subscription or
purchase. For the purposes of this subparagraph (c), the number of shares of
Common Stock at any time outstanding shall not include shares held in the
treasury of the Company. "Fair Market Value" shall mean, as to shares of Common
Stock the simple average of the daily Closing Prices for the ten (10)
consecutive Trading Days immediately preceding the day in question.

                  7. (a) In case of a distribution to all holders of the
Company's Common Stock of shares of its capital stock (other than Common Stock)
or evidences of its indebtedness or property, or a capital reorganization of the
Company, a reclassification of the Common Stock, a consolidation of the Company
with or merger of the Company into another corporation or entity (but only if
such consolidation or merger is consummated after December 31, 2000) (other than
a consolidation or merger in which the Company is the continuing entity) or a
sale of the properties and assets of the Company (but only if such sale is
consummated after December 31, 2000) as, or

                                      -7-

<PAGE>   8

substantially as, an entirety and distribution of the proceeds of sale, after
such distribution, capital reorganization, reclassification, consolidation,
merger or sale, on exercise of this Warrant the Holder will receive the number
of shares of stock or other securities or property which the Holder would have
received if this Warrant had been exercised immediately before the first such
corporate event and the Holder had retained what it would have received as a
result of each such corporate event. The split or subdivision or combination of
shares of Common Stock at any time outstanding into a greater or lesser number
of shares of Common Stock will not be deemed to be a reclassification of the
Common Stock of the Company for the purposes of this paragraph. The Company will
not effect any consolidation or merger unless prior to or simultaneously with
its consummation the successor entity (if other than the Company) resulting from
the consolidation agrees in writing to deliver to the Holder of this Warrant on
exercise of this Warrant the shares of stock or other securities or property to
which the Holder becomes entitled because of that exercise.

                      (b) In the event that at any time prior to December 31,
2000, the Company (i) consolidates or merges with another corporation or entity
(other than a consolidation or merger of the Company in which the Company is the
continuing entity) or (ii) sells its properties and assets as, or substantially
as, an entirety and distributes the proceeds, this Warrant shall terminate
immediately upon the consummation of such consolidation, merger or sale and the
Holder shall be promptly paid by the Company (or the Company's
successor-in-interest, as the case may be) a dollar amount equal to the number
of RFMD Shares purchasable hereunder multiplied by the positive difference (if
any) between the Closing Price of the Common Shares as of the last Trading Day
immediately prior to the effective date of such consolidation, merger or sale
and $71.50 (as adjusted for any stock divisions, stock combinations, stock
recapitalizations, stock reclassifications, stock dividends or similar
transactions occurring after the date of this Warrant).

                  8. Whenever the Warrant Price and/or the number of RFMD Shares
is adjusted as provided in this Warrant, the Company will compute the adjusted
Warrant Price and/or the number of RFMD Shares or other assets the Holder would
receive on exercise of this Warrant in full and will provide a notice to the
Holder within thirty (30) days of the date of such adjustment stating that the
Warrant Price and/or the number of RFMD Shares has been adjusted and setting
forth the adjusted Warrant Price and/or the number of RFMD Shares and what the
Holder would receive upon exercise of this Warrant in full. The Company will
also provide a notice to the Holder describing any event that would trigger an
adjustment in the Warrant Price and/or the number of RFMD Shares in the absence
of the last paragraph of paragraph 5. Such notice will be given within thirty
(30) days of the effective date of such event.

                  9. The Company will at all times keep a sufficient number of
authorized but unissued RFMD Shares to permit exercise in full of this Warrant.
The Company represents and warrants that all RFMD Shares which are delivered on
exercise of this Warrant (and payment of the Warrant Price therefor) will, upon
delivery, be duly issued, fully paid and non-assessable.

                  10. The Holder will not, by reason of holding this Warrant,
have any right to vote, to receive dividends or other distributions, or any
other rights of a shareholder, with regard to the RFMD Shares.

                  11. The Holder may not assign, sell or otherwise transfer,
dispose of, make any short sale of, pledge or hypothecate, grant any option for
the purpose of, or enter into any hedging, synthetic sale or similar transaction
with the same economic effect as a sale of, this Warrant or any of the Holder's
rights under it, except (i) to a corporation controlling, controlled by or under
common control with the Holder (which

                                      -9-

shall take this Warrant subject to the transfer restrictions in this paragraph)
or (ii) by merger or consolidation of Holder with or into another corporation or
entity if the Holder is not the surviving corporation (which shall take this
Warrant subject to the transfer restrictions in this paragraph), and any
transfer or attempted transfer or other prohibited assignment of this Warrant
will be null and void and of no force or effect.

                  12. Any notices or other communications to the holder of this
Warrant will be addressed to TRW Inc., Space & Electronics Group, One Space

   500,000 Shares                                          WARRANT NO. 99-2

                             RF MICRO DEVICES, INC.

                          A North Carolina Corporation

                             (Void after 5:00 p.m.,
                   Washington D.C. Time, on December 31, 2001)

                  THIS CERTIFIES THAT, for value received, TRW Inc. (the
"Holder") is entitled at any time after December 31, 2000 and at any time before
5:00 p.m. Washington D.C. time on December 31, 2001 (the "Expiration Time") to
purchase up to 500,000 (five hundred thousand) shares (the "RFMD Shares") of
common stock, no par value (the "Common Shares"), of RF Micro Devices, Inc. (the
"Company") at the price per RFMD Share as determined in paragraph 1 of this
Warrant, subject to adjustment as provided in paragraph 5 of this Warrant (that
price, as it may be adjusted from time to time, being referred to as the
"Warrant Price").

                  1. (a) The Warrant Price shall be the average of the Closing
Prices of the Common Shares during the ten (10) Trading Days immediately
preceding December 31, 2000 (the "Pricing Period") multiplied by 0.75. The
Closing Price for each day shall be the reported last sales price regular way
or, in case no such reported sale

<PAGE>   2


takes place on such day, the average of the reported closing bid and asked
prices regular way, in either case on the New York Stock Exchange or, if the
Common Shares are not listed or admitted to trading on such Exchange, on the
principal national securities exchange on which the Common Shares are listed or
admitted to trading (based on the aggregate dollar value of all securities
listed or admitted to trading) or, if not listed or admitted to trading on any
national securities exchange, on the NASDAQ National Market System or, if the
Common Shares are not listed or admitted to trading on any national securities
exchange or quoted on the NASDAQ National Market System, the average of the
closing bid and asked prices in the over-the-counter market as furnished by any
New York Stock Exchange member firm selected from time to time by the Company
for that purpose. The Closing Prices during the Pricing Period shall be adjusted
to take into account any stock divisions, stock combinations, stock
recapitalizations or reclassifications, stock dividends and the like in order
that the Closing Prices during the entire Pricing Period shall have the same
reference point as the Closing Price immediately prior to December 31, 2000. The
average of the Closing Prices shall be a simple average and shall not be
weighted according to trading volume or any other manner. "Trading Day" shall
mean a day on which the national securities exchange or the NASDAQ National
Market System used to determine the Closing Price is open for the transaction of
business or the reporting of trades or, if the Closing Price is not so
determined, a day on which the New York Stock Exchange is open for the
transaction of business.

                  (b) This Warrant shall not be exercisable, and shall become
null and void, unless the Company has "Annualized Sales" of Licensed Products
(as defined in the License Agreement, dated as of November 15, 1999, between the
Company and the

                                      -2-
<PAGE>   3

Holder) of at least ******. For the purposes of this Warrant, "Annualized
Sales" may be calculated as of any fiscal quarter ending on or prior to the
Expiration Time and shall be equal to the product of four times the gross
revenues from the sale of the Licensed Products during such fiscal quarter,
computed in accordance with generally accepted accounting principles. The
Company shall deliver to the Holder a regular quarterly report that shows its
revenues from sales of Licensed Products during the preceding fiscal quarter and
its Annualized Sales of Licensed Products as of such fiscal quarter end. The
Expiration Time shall be extended until the fifth (5th) business day after the
delivery by the Company of its quarterly report for the quarter ending December
31, 2001 if the Annualized Sales threshold has not been met prior to such
quarter. In the event of a "Change in Control" of the Company at any time prior
to the Expiration Time, the Annualized Sale requirement described in this
subparagraph shall have no effect and the Warrant will become exercisable at the
time provide elsewhere in, and pursuant to the terms of, this Warrant. As used
herein, "Change in Control" means the occurrence of any of the following: (i)
the sale by the Company of all or substantially all of its assets; or (ii) the
participation by the Company as constituent corporation in a merger or
consolidation if the shareholders of the Company immediately prior to the
effective time of such transaction own less than fifty percent (50%) of the
outstanding voting securities of the surviving corporation.

                  2. To exercise this Warrant, this Warrant must be surrendered
prior to the Expiration Time at the office of the Company at 7625 Thorndike
Road, Greensboro, North Carolina 27409 (or such other address as the Company may
specify in writing to the Holder of this Warrant at least ten days before this
Warrant is exercised) with the attached Notice of Exercise duly completed and
executed, accompanied by evidence of a wire transfer of immediately available
funds to the Company's money market account

#___________ with Silicon Valley Bank, Santa Clara, California, ABA Routing
#_________ (or such other account as the Company may specify in writing to the
Holder of this Warrant at least ten days before this Warrant is exercised) in
full payment of the purchase price of the RFMD Shares with respect to which this
Warrant is exercised. This Warrant may be exercised in whole or in part as to
any whole number of RFMD Shares. If this Warrant is exercised in part, upon
surrender of this Warrant for exercise, the Company will issue to the Holder a
new Warrant to purchase the remaining number of RFMD Shares which may be
purchased upon exercise of this Warrant (before taking account of adjustments by
reason of paragraphs 5, 6 and 7) and the number of RFMD Shares with respect to
which it is exercised (before taking account of adjustments by reason of
paragraphs 5, 6 and 7). The new Warrant will bear the same date as this Warrant
and will be identical to this Warrant in all respects, except as to the number
of RFMD Shares as to which it may be exercised.

                  3. The RFMD Shares as to which this Warrant is exercised will
be deemed to be issued when this Warrant is exercised. Holder agrees that prior
to the exercise of this Warrant, it will comply with the provisions of the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act")
as in effect from time to time. If action is taken by the Federal Trade
Commission or the United States Department of Justice to enjoin Holder's
exercise of this Warrant, the Company agrees reasonably to cooperate with Holder
to contest such enjoinment at the expense of this Holder. A certificate
representing the RFMD Shares will be issued to the Holder of this Warrant
promptly after it is exercised. The certificate may bear a legend to the effect
that the RFMD Shares it represents have not been registered under the Securities
Act of 1933, as amended (the "Act"), or any applicable state securities laws,
and may only be

                                      -4-
<PAGE>   5

transferred in a transaction registered under the Act or such laws or exempt
from the registration requirements of the Act or such laws. In addition, any
other legend required by any other agreement between the Company and Holder may
be included on the certificate or certificates for such RFMD Shares.

                  4. This Warrant will expire, and the right to purchase the
RFMD Shares by exercise of this Warrant will terminate, at the Expiration Time;
provided, however, that if Holder has complied with the filing provisions of the
HSR Act at least thirty days prior to the Expiration Time, but the waiting
period imposed by the HSR Act has not terminated or lapsed, then the Expiration
Time will be extended until ten days after such termination or lapse. After that
time this Warrant will be void.

                  5. The Warrant Price will be subject to adjustment from time
to time as follows:

                     (a) If, at any time after December 31, 2000, the Company
(i) pays a dividend on its Common Stock in Common Stock, (ii) splits or
subdivides its outstanding shares of Common Stock, or (iii) combines its
outstanding shares of Common Stock into a smaller number of shares, the Warrant
Price in effect immediately prior to each of those events will be adjusted
proportionately so that the adjusted Warrant Price will bear the same relation
to the Warrant Price in effect immediately prior to the event as the total
number of shares of Common Stock outstanding immediately prior to the event will
bear to the total number of shares of Common Stock outstanding immediately after
the event.

                     (b) An adjustment made pursuant to subparagraph (a) of
this paragraph will become effective immediately after the corresponding record
date

                                      -5-

<PAGE>   6

         in the case of a dividend and immediately after the effective date in
         the case of a subdivision or combination.

                  No adjustment of the Warrant Price will be made if the amount
of such adjustment would be less than 2% of the Warrant Price, but any such
adjustment that would otherwise be required to be made and has not previously
been made will be carried forward and be made at the time of and together with
the next subsequent adjustment which, together with all adjustments so carried
forward, amount in the aggregate to 2% or more of the Warrant Price. As used in
this Warrant, "Common Stock" includes any class of the Company's capital stock,
now or hereafter authorized, having the right to participate in the distribution
of either earnings or assets of the Company without limitation as to amount or
percentage. At no time will the Warrant Price be less than $.01 per share.

                  6. (a) In case the Company shall at any time or from time to
time (i) subdivide its outstanding shares of Common Stock into a greater number
of shares or (ii) combine its outstanding shares of Common Stock into a smaller
number of shares, then the number of RFMD Shares, in effect immediately prior to
such event, shall be porportionately increased in the case of a subdivision and
proportionately decreased in the case of combination. Any adjustment under this
subparagraph 6(a) shall become effective at the close of business on the date
the subdivision or combination becomes effective.

                     (b) In case the Company shall at any time or from time to
time makes, or fixes a record date for the determination of holders of the
Common Stock entitled to receive, a dividend or other distribution payable in
additional shares of Common Stock, then and in such event the number of RFMD
Shares then in effect shall

                                      -6-


<PAGE>   7

be increased as of the time of such issuance or, in the event such record date
is fixed, as of the close of business on such record date, by multiplying the
number of RFMD Shares then in effect by a fraction (x) the denominator of which
is the total number of shares of the Common Stock issued and outstanding
immediately prior to the time of such issuance or the close of business on such
record date, and (y) the numerator of which shall be the total number of shares
of the Common Stock issued and outstanding immediately prior to the time of such
issuance or the close of business on such record date plus the number of shares
of the Common Stock issuable in payment of such dividend or distribution;
provided, however, that if such record date is fixed and such dividend is not
fully paid or if such distribution is not fully made on the date fixed therefor,
the number of RFMD Shares shall be recomputed accordingly based on the number of
additional shares of Common Stock actually issued as of the close of business on
the date originally fixed for the payment of such dividend or the making of such
distribution and thereafter the number of RFMD Shares shall be adjusted pursuant
to this subparagraph 6(b) at the time of actual payment of any additional
dividends or distributions of Common Stock.

                      (c) In case the Company shall issue rights or warrants to
all or substantially all holders of its Common Stock entitling them to subscribe
for or purchase shares of Common Stock at a price per share less than the Fair
Market Value (as hereinafter defined) per share of the Common Stock on the date
fixed for the determination of shareholders entitled to receive such rights or
warrants, the number of RFMD Shares, in effect at the opening of business on the
day following the date fixed for such determination, shall be increased by
multiplying such number of RFMD Shares by a fraction of which the denominator
shall be the number of shares of Common Stock outstanding at the close of
business on the date fixed for such determination plus the number of shares of
Common Stock which the aggregate of the offering price of the total number of
shares of Common Stock so offered for subscription or purchase would

                                      -7-


<PAGE>   8

purchase at such Fair Market Value, and the numerator shall be the number of
shares of Common Stock outstanding at the close of business on the date fixed
for such determination plus the number of shares of Common Stock so offered for
subscription or purchase, such adjustment to become effective immediately after
the opening of business on the day following the date fixed for such
determination; provided, however, in the event that all the shares of Common
Stock offered for subscription or purchase are not delivered upon the exercise
of such rights or warrants, the number of RFMD Shares shall be readjusted to the
number of RFMD Shares that would have been in effect had the numerator and the
denominator of the foregoing fraction and the resulting adjustment been made
based upon the number of shares of Common Stock actually delivered upon the
number of shares of Common Stock offered for subscription or purchase. For the
purposes of this subparagraph (c), the number of shares of Common Stock at any
time outstanding shall not include shares held in the treasury of the Company.
"Fair Market Value" shall mean, as to shares of Common Stock the simple average
of the daily Closing Prices for the ten (10) consecutive Trading Days
immediately preceding the day in question.

                  7. (a) In case of a distribution to all holders of the
Company's Common Stock of shares of its capital stock (other than Common Stock)
or evidences of its indebtedness or property, or a capital reorganization of the
Company, a reclassification of the Common Stock, a consolidation of the Company
with or merger of the Company into another corporation or entity (but only if
such consolidation or merger is consummated after December 31, 2000) (other than
a consolidation or merger in which the Company is the continuing entity) or a
sale of the properties and assets of the Company (but only if such sale is
consummated after December 31, 2000) as, or substantially as, an entirety and
distribution of the proceeds of sale, after such distribution, capital
reorganization, reclassification, consolidation, merger or sale, on


                                      -8-
<PAGE>   9

exercise of this Warrant the Holder will receive the number of shares of stock
or other securities or property which the Holder would have received if this
Warrant had been exercised immediately before the first such corporate event and
the Holder had retained what it would have received as a result of each such
corporate event. The split or subdivision or combination of shares of Common
Stock at any time outstanding into a greater or lesser number of shares of
Common Stock will not be deemed to be a reclassification of the Common Stock of
the Company for the purposes of this paragraph. The Company will not effect any
consolidation or merger unless prior to or simultaneously with its consummation
the successor entity (if other than the Company) resulting from the
consolidation agrees in writing to deliver to the Holder of this Warrant on
exercise of this Warrant the shares of stock or other securities or property to
which the Holder becomes entitled because of that exercise.

                     (b) In the event that at any time prior to December 31,
2000, the Company (i) consolidates or merges with another corporation or entity
(other than a consolidation or merger of the Company in which the Company is the
continuing entity) or (ii) sells its properties and assets as, or substantially
as, an entirety and distributes the proceeds, this Warrant shall terminate
immediately upon the consummation of such consolidation, merger or sale and the
Holder shall be promptly paid by the Company (or the Company's
successor-in-interest, as the case may be) a dollar amount equal to the number
of RFMD Shares purchasable hereunder multiplied by the positive difference (if
any) between the Closing Price of the Common Shares as of the last Trading Day
immediately prior to the effective date of such consolidation, merger or sale
and $71.50 (as adjusted for any stock divisions, stock combinations, stock
recapitalizations, stock reclassifications, stock dividends or similar
transactions occurring after the date of this Warrant).

                  8. Whenever the Warrant Price and/or the number of RFMD Shares
is adjusted as provided in this Warrant, the Company will compute the adjusted
Warrant

                                      -9-
<PAGE>   10

Price and/or the number of RFMD Shares or other assets the Holder would receive
on exercise of this Warrant in full and will provide a notice to the Holder
within thirty (30) days of the date of such adjustment stating that the Warrant
Price and/or the number of RFMD Shares has been adjusted and setting forth the
adjusted Warrant Price and/or the number of RFMD Shares and what the Holder
would receive upon exercise of this Warrant in full. The Company will also
provide a notice to the Holder describing any event that would trigger an
adjustment in the Warrant Price and/or the number of RFMD Shares in the absence
of the last paragraph of paragraph 5. Such notice will be given within thirty
(30) days of the effective date of such event.

                  9. The Company will at all times keep a sufficient number of
authorized but unissued RFMD Shares to permit exercise in full of this Warrant.
The Company represents and warrants that all RFMD Shares which are delivered on
exercise of this Warrant (and payment of the Warrant Price therefor) will, upon
delivery, be duly issued, fully paid and non-assessable.

                  10. The Holder will not, by reason of holding this Warrant,
have any right to vote, to receive dividends or other distributions, or any
other rights of a shareholder, with regard to the RFMD Shares.

                  11. The Holder may not assign, sell or otherwise transfer,
dispose of, make any short sale of, pledge or hypothecate, grant any option for
the purpose of, or enter into any hedging, synthetic sale or similar transaction
with the same economic effect as a sale of, this Warrant or any of the Holder's
rights under it, except (i) to a corporation controlling, controlled by or under
common control with the Holder (which shall take this Warrant subject to the
transfer restrictions in this paragraph) or (ii) by merger or consolidation of
Holder with or into another corporation or entity if the Holder

                                      -10-


<PAGE>   11

is not the surviving corporation (which shall take this Warrant subject to the
transfer restrictions in this paragraph), and any transfer or attempted transfer
or other prohibited assignment of this Warrant will be null and void and of no
force or effect.

                  12. Any notices or other communications to the holder of this
Warrant will be addressed to TRW Inc., Space & Electronics Group, One Space
Park, Redondo Beach, California 90278, Attention: Vice President, Finance, with
a copy to TRW Inc., 1900 Richmond Road, Cleveland, Ohio 44124, Attention:
Secretary, or to such other address as the Holder may specify in writing to the
Company.

                  13. This Warrant will be governed by, and construed under, the
laws of the State of North Carolina.

                  14. This Warrant may not be modified without the written
consent of the Company and the Holder.
