摘要

随着通信系统面临的电磁工作环境越来越严峻，高功率容量、低插损、快响应时间的电磁脉冲防护模块对其射频前端电路的保护越发的重要起来.本文主要基于PIN二级管射频限幅的原理，构建了PIN二极管的时域等效电路模型，利用去嵌入阻抗场计算方法提取相应电路的S参数，优化设计匹配网络，并采用无源多级PIN二极管结构，设计了一个工作于0~200MHz，插入损耗小于0.15dB，驻波比小于1.4dB，响应时间小于1ns的短波通信电磁脉冲防护模块.结合PIN二极管时域等效电路模型，利用先进设计系统（Advanced Design System，ADS）仿真软件对电磁脉冲防护模块限幅性能进行仿真，并对加工出来的电磁脉冲防护模块进行了测试，结果验证了各项指标满足要求.

Abstract

With the increasing threat of extremely difficult environment of communication system

the electromagnetic pulse protection module which has the characteristics of high power capacity

high isolation

low insertion loss and fast response time is becoming increasingly important.In this paper

the principle of radio frequency limiting of PIN is studied

and the structure of passive multistage PIN diode is adopted.Through the establishment of its field simulation model

the corresponding S parameters are extracted

and the optimal matching network is optimized.The electromagnetic pulse protection module which works at 0~200MHz has insertion loss of less than 0.15dB

the voltage standing wave ratio (VSWR) of less than 1.4

response time of less than 1ns is designed.Combined with self-built PIN diode model

ADS simulation software is used to simulate the limiting performance of electromagnetic pulse protection module.The result shows that all the indexes meet the requirements.
