摘要

本文阐述了Doherty功率放大器的设计。详细分析了多尔蒂功率放大器的工作原理。并介绍了匹配网络的设计过程。利用MRF8S21120H晶体管对频段为2.11-2.17GHz的Doherty功率放大器进行了仿真。P1dB在52dBm以上，6dB回退区效率在41%以上。在6dB后退点时，效率提高了12.1%。在6.5dB后退点，上IMD3为-36.4dBc，下IMD3为-36dBc。它具有可接受的线性。

Design of Doherty power amplifier for base-station application

This paper expounds on the design of Doherty power amplifier. The principle of Doherty power amplifier is analyzed detailedly. We also introduce the procedure of designing matching networks. A Doherty power amplifier at band 2.11-2.17GHz is simulated with the MRF8S21120H transistor. The P1dB is above 52dBm, and its efficiency is above 41% in 6dB back-off region. It demonstrates an efficiency improvement of 12.1% at 6dB back-off point. And the upper IMD3 is -36.4dBc, the lower IMD3 is -36dBc, at 6.5dB back-off point. It has an acceptable linearity.
