Abstract :
5-GHz 20-watt GaAs FET amplifier using two state-of-the-art high power FETs in the final stage was developed for MLS applications. GaAs FET limiter with unique input/output characteristics and efficient operation of the final FETs were studied for this purpose. Stabilization of output power within 1dB peak-to-peak by means of open loop control was achieved of PIN diode attenuator.
