摘　　要：宽带大功率微波功放在通信对抗中的应用越来越广泛，而宽带功放的设计在国内还处于起步阶段。介绍了一种用ADS技术来设计宽带微波功放模块的方法，利用MESFET功放管提供的静态Ⅳ特性曲线和小信号S参数，分别优化放大器的输入输出匹配电路，以期达到宽频带大输出功率的目的。通过一个1～2GHz 10W功放模块的设计实例，较为详细地介绍了ADS技术在设计过程中的应用，最后给出了试验电路的测试结果。High-power wideband microwave power amphfiers are increasingly extensively applied in Communication Countermeasure while wideband power amplifier design is still in initial stage in China. This paper introduces a method of designing wideband microwave power amplifier module with ADS technology. This method uses the static IV characteristic curve and S parameter of small signals provided by MESFET power amplifying tube to optimize the I/O matching circuits respectively so as to implement wideband high-power output. With a design case of 1～2GHz 10W power-amplifying module, the application of ADS technology in design processes is described in detail and the test results of experimental circuits are provided in conclusion.
