59 -- DEVELOP SOLID-STATE TRANSMITTER COMPONENTS FOR HIGH POWER GENERATION AT KA-BAND SOL N68936-98-R-0129 DUE 060898 POC Linda Long, Contract Specialist, (760) 939-4232 The Naval Air Warfare Center Weapons Division, China Lake, CA intends to procure development of solid-state transmitter components for high power generation at Ka-band on a fully competitive basis. The effort entails three parts: (1) developing Impact Avalanche Transit Time (IMPATT) diode designs for high pulse power generation which meet stated performance specifications (Frequency of 35GHz, Peak output power of 8 watts, Duty cycle of 20-30% range, Pulse length of 30 microseconds, Conversion efficiency of equal to/greater than 16%), growing the IMPATT material as specified using GaAs, characterizing grown IMPATT wafer material to establish its suitability for further processing, processing the material into IMPATT chips, mounting the chips into suitable packages, conducting RF testing and evaluation of the IMPATT device technology, and developing and fabricating an IMPATT diode oscillator mount suitable to conduct testing as well as a biasing modulator to be used in the testing and evaluation of the IMPATT devices being developed in the program; (2) to develop and demonstrate power combining of at least four of the discrete packaged IMPATT devices that were developed in part one and which meet performance specifications at Ka-band frequency of 35Ghz; and (3) to develop and demonstrate a power combining structure that allows the combining of twice (2X) as many IMPATT devices in the same specified unit volume as presented in part two and which meets performance specifications at Ka-band frequency of 35GHz. The period of performance is 18 months. All qualified sources may submit a proposal which will be considered by the government. Requests shall be in writing to the above referenced address or telefax (760) 939-7510. See Note(s): 26. (0105)
