摘要
基于PIN二极管射频限幅的原理,分析了尖峰泄露产生的原因并提出了解决方法。在此基础上采用无源多级PIN二极管结构,提取相应防护电路的S参数,以设计优化匹配网络,研制了工作于1~200MHz、插入损耗小于0.156dB、响应时间小于1ns的射频前端电磁脉冲防护模块。结合PIN二极管模型,利用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。
This paper studies the principle of radio frequency limiting of PIN,and analyzes how the spike leakage occurs in EMP protection and how to restrain it.On this basis,the structure of passive multi-stage PIN diode is adopted.Through the establishment of its field simulation model,the corresponding Sparameters are extracted,and the optimal matching network is optimized.The electromagnetic pulse protection module which works at 1-200 MHz with insertion loss of less than 0.15 dB,VSWR of less than 1.4 dB,response time of less than 1 ns is designed.Combined with 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.
