摘　　要：本文研究了一种应用于MHz级别的推挽式E类功率放大器,并通过Matlab软件的simulink进行了电路仿真。文章分析了该电路在不同负载下的输出谐波情况,并结合仿真进行了电路搭建和实验验证。研究结果表明,推挽式E类电路具有更低的谐波失真。这种推挽式结构更适用于宽负载的高频应用场合。通过定量分析推挽式E类功率放大电路的相关公式,本文为该电路在MHz应用的设计与优化提供了实用的指导。In this paper, a Class E push-pull power amplifier circuit applied to MHz level is studied, and the circuit simulation is carried out by Matlab software simulink. In this paper, the output harmonics of the circuit under different loads are analyzed, and the simulation and experimental verification are carried out based on the circuit construction. The results show that push-pull Class E circuits have lower harmonic distortion. This push-pull structure is suitable for high frequency applications with wide loads. By quantitative analysis of the formula of push-pull Class E power amplifier circuit, this paper provides practical guidance for the design and optimization of this circuit in MHz application.
