SOLID STATE WIDEBAND POWER AMPLIFIER DEVELOPMENT AT 20 AND 44 GHz

International Telemetering Conference Proceedings / October 13-15, 1981 / Bahia Hotel, San Diego, CaliforniaTwo amplifier developments centered at 20 GHz based on GaAs IMPATT diodes will be discussed. The on-going developments of a 20 GHz communication amplifier sponsored by NASA Lewis using injection locking and resonant cavity combiner will be reviewed. A wideband 20 GHz amplifier to achieve 20 Watt 1 GHz bandwidth based on 3-dB hybrid couplers and stable mode of amplification, along with the results obtained from the constant voltage mode of amplification will be discussed. A wideband solid state amplifier designed as a driver for a 44 GHz terminal transmitter will be described. The amplifier is designed for 2 GHz 1-dB bandwidth centered at 44.5 GHz, with an overall gain of 40 dB. A six-stage design is used to accomplish 500 mW output power. Low cost construction and mechanical ruggedness are emphasized in this design.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
