ITEM 1.01.  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

        On January 16, 2006, Endwave Corporation entered into a frame purchase
agreement with Siemens S.p.A. As with all frame agreements, the Siemens
agreement provides for the general terms and conditions of purchases of Endwave
products by Siemens, but does not contain any obligation to purchase by Siemens.
Any purchase obligations would be evidenced by purchase orders issued pursuant
to the terms of the frame agreement. The specific Endwave products covered by
this agreement include various models of microwave radio frequency transceivers
to be supplied for Siemens' global cellular telephone network and backhaul
market products. The term of the agreement is 36 months, and applies to all
purchases of radio transceiver orders during the term from any qualifying
Siemens operating unit, affiliate, or subsidiary. Payments to Endwave shall be
denominated in US dollars, using a 45-day electronic payment period. A companion
logistics appendix with subsumed annexes defines operating rules, including
electronic forecasting, cancellation flexibility rules, buffer stocking, and
unit repair.



                                   SIGNATURES

        Pursuant to the requirements of the Securities Exchange Act of 1934, the
Company has duly caused this report to be signed on its behalf by the
undersigned hereunto duly authorized.
