Design of Linear Power Amplifier Based on OFDM Yang Pengfei

本文分析了OFDM调制解调方式在峰均比方面的特点及其对功率放大器的线性要求，描述了提高功率放大器线性指标的几种典型方法，在此基础上设计了一种解决某微波通信设备射频通道线性指标的功率放大器，并给出了测试结果。

This paper analyzes the features of peak-to-average ratio （PAR） of OFDM modula- tion/demodulation method and its linear requirement for power amplifiers, de- scribes several typical methods of improving the linearity of power amplifiers. On this basis, it designs an power amplifier to solve the RF channel linear parameters of a microwave communication equipment. The test results are also given.
