摘　　要：针对高功率微波波形参数对限幅器温度分布特性的影响,基于双级PIN限幅器的场路协同仿真模型对微波脉冲幅值、频率对温度分布的影响展开了仿真研究。结果表明:微波脉冲幅值、频率的提升会使双级PIN限幅器中PIN二极管的高温区域分布向P区拓展、高温区域分布范围扩大;相对而言,微波脉冲幅值对温度分布的影响更为显著,频率对温度分布的影响相对较小。A field-circuit co-simulation model of a two-stage PIN limiter was built to explore the influence of high-power microwave signal parameters on the temperature distribution of the limiter.The simulation results indicate that the increase in microwave pulse amplitude or frequency can expand the PIN diode's high-temperature region inside the two-stage PIN limiter towards the P-region.Compared with the frequency,the amplitude of the microwave pulse has a more significant impact on the temperature distribution of the PIN limiter.
