This Post-Effective Amendment No. 1 amends the Registration Statement on
Form S-3 (No. 333-19907) of Digital Microwave Corporation (the "Registrant")
filed on January 16, 1997 and last amended on March 13, 1997 (the "Registration
Statement"). Pursuant to the Registration Statement, 2,530,000 shares of the
Registrant's Common Stock were registered under the Securities Act of 1933, as
amended. Between March 13, 1997, the date on which the Registration Statement
was declared effective by the Securities and Exchange Commission, and the date
hereof, 2,200,000 shares of the Common Stock were sold. In connection with the
underwriting arrangements relating to the sale of the Common Stock, the
Registrant granted the underwriters an option to purchase up to 330,000 shares
of Common Stock, which has not been exercised and has since expired. Therefore,
the Registration Statement is hereby further amended to deregister 330,000
shares of Common Stock, thereby reducing the number of shares covered by the
Registration Statement to 2,200,000.
