摘　　要：基于Smith圆图设计射频匹配电路,提出了大功率射频放大电路的设计方法,采用MRF9060芯片,运用如Pspice和ADS等开发软件,实现了包括直流偏置电路、保护电路、匹配滤波电路以及射频放大电路在内的整体设计,并给出了对系统增益、回波损耗等指标的仿真结果。Based on Smith chart to design RF match network, a high-power RF power amplifying circuit is designed. By using Motorola MRF9060, and the commerce softwares such as Pspice and Advanced Design System（ADS）, further development is carried out. An integrated system including DC bias circuit, the protection circuit, RF match network and RF power amplifying circuit has been implemented. Meanwhile the simulation results of system gain, return loss, etc. are presented.
