摘要

本文研究了用于雷达s波段应用的大功率放大器CGHV31500F。放大器模块基于GaN HEMT封装的内部匹配晶体管，在脉冲范围内提供超过500w的功率。建立了该放大器的非线性模型，并对标准雷达信号和未来可能出现的QAM信号的非线性失真进行了预测。

Nonlinear Distortion in a Microwave High Power Amplifier

In this paper the high-power amplifier CGHV31500F designed for the radar S-Band application is studied. The amplifier module is based on GaN HEMT encapsulated internally matched transistor, delivering more than 500 W in a pulse regime. Nonlinear model of this amplifier was developed and nonlinear distortion of a standard radar signal and of possible future QAM signals are predicted.
