Abstract

A high-efficiency and lightweight solid-state power amplifier (SSPA) and traveling-wave-tube amplifier (TWTA) for use in a 20-GHz-band satellite transponder have been developed. The SSPA features a compact, highly efficient output power combiner. The output power of the SSPA is 3.3 W with an efficiency of 21% at 18.365 GHz, and it weighs 750 g. The TWTA features a high-efficiency, compact size three-stage collector and high switching frequency power supply. The TWTA delivers an output power of 12 W with 31% efficiency at 20.465 GHz and weighs 1430 g.<>
