摘要
本文对微波固态功率放大器的最新进展及其相对与真空管放大器的优越性作了较详细的描述 ,介绍了固态功放在某数字电视上行站中的成功应用 ,笔者认为固态功放将在卫星通信地球站中逐渐代替行波管、速调管放大器。
This paper describes the recent advances in microwave solid state power amplifier (SSPA) and its advantages over vacuum tube amplifiers. A successful application example of SSPAs in a satellite digital TV uplink earth station is given. The author believes that Travelling Wave Tube Amplifiers (TWTAs) and Klystron Power Amplifiers (KPAs) would be replaced by using SSPAs in satellite communication earth stations.
