Abstract :
Solid-state power amplifiers(SSPAs) have-been significantly improving in the past years and gradually replacing travelling wave tube amplifiers (TWTAs) in the area of microwave and mm-wave communication systems such as terrestrial communications equipment and satellite transponders. This paper surveys the recent research and developmental activities on solid state power amplifiers and related key devices in Japan, focussing on device structures, circuit approaches and processing technologies.
