摘　　要：微波通讯系统中,射频功率放大器对发射机系统的性能起着关键作用.研究放大器的基本原理发现,稳定放大器的工作电流,可使功率器件保持稳定的性能.本文实验中使用的射频功放是CHA5051,为驱动PA和CHA5052为末级PA组成的模块,选择LM2904D及三极管BCW60设计电压调节电路.系统依据控制漏极降压电阻的降压来控制漏极电流,达到功率放大器的电流恒定.引入ADS仿真软件的模拟功能,完成实际电路的设计.通过不同温度环境的测试达到设计规范.The radio frequency power amplifier plays a key role in the performance of the transmitter system. The basic principle of the amplifier is studied. The results show that the stable operating current of the amplifier can keep the power device stable. This study use of RF power amplifier to drive CHA5051 CHA5052 PA and final stage PA is composed of modules, select LM2904D and triode BCW60 design voltage regulating circuit. In order to make the current of the power amplifier constant, the system controls the drain current by controlling the drain voltage. The simulation function of ADS simulation software is introduced to accomplish the design of the actual circuit. The design specifications are reached through tests of different temperature environments.
