摘　　要：第五代移动通信(5G)技术已经慢慢来临,但是这些移动通信系统的工作频段各不相同。因此,不同的频段在工作时需要对应不同的基站设备,必然会造成对大量资源的浪费。在这种情况下,无线通信基站的多频段使用技术占据非常重要的地位,同时对于双频甚至多频带功率放大器的设计要求也越来越紧迫。本文在此背景下从5个方面即静态工作点的仿真、功放负载的选取、功放匹配电路的设计、硬件实物的加工测试以及功放的非线性补偿详细介绍了整个设计过程。双频点的临近信道功率比(Adjacent Channel Power Ratio,ACPR)都能满足小于-46.7 dBc的要求。The fifth generation mobile communication(5G)technology has come slowly,but the working frequency bands of these mobile communication systems are different.Therefore,different frequency bands need to correspond to different base station equipment when working,which will inevitably cause a waste of a lot of resources.In this case,the multi band use technology of wireless communication base station occupies a very important position.At the same time,the design requirements of dual band or even multi band power amplifier are becoming more and more urgent.Under this background,this paper introduces the whole design process in detail from five aspects:the simulation of static working point,the selection of power amplifier load,the design of power amplifier matching circuit,the processing and testing of hardware and the nonlinear compensation of power amplifier.The Adjacent Channel Power Ratio(ACPR)of dual frequency points can meet the requirements of less than-46.7 dBc.
