砷化镓场效应晶体管的技术已经证明:这种器件可以取代空间飞行器上通信转发器的行波管。目前,美国无线电公司(RCA)为国际通信卫星研制的C波段场效应晶体管取得了一些阶段性成果。
Gallium arsenide field-effect transistor technology has proven that this device can replace the spacecraft communication transponder traveling wave tube. At present, Radio American Corporation (RCA) has achieved some milestones for C-band field-effect transistors developed by International Telecommunications Satellite.
