摘要: 为了研究PIN二极管对快上升沿电磁脉冲的响应,基于PIN二极管时域等效电路模型,仿真研究了PIN二极管电路在快上升沿电磁脉冲作用下的瞬态电压特性。以集总参数巴特沃斯低通滤波器电路为原型,通过拟合二极管寄生参数值,结合键合金丝电感参数,设计了一款基于PIN二极管的快上升沿电磁脉冲防护电路模块,并对防护电路模块的快上升沿电磁脉冲防护性能进行了测试。结果表明:在1~250 MHz短波、超短波频段内,防护模块的插损小于0.38 dB;当输入方波脉冲为4 000 V时, 限幅响应时间小于2 ns,输出电平小于30 V,满足快上升沿电磁脉冲的防护要求。

Abstract: The fast rise time electromagnetic pulse (FREMP) is an important cause of damage to electronic equipment, and the PIN diode can effectively suppress electromagnetic pulse. In order to investigate the transient response of PIN diodes to FREMP, a time-domain equivalent circuit model based on PIN diodes is adopted. And the transient voltage characteristic of PIN diode circuit under the effect of FREMP is analyzed. Considering the parasitic components of PIN diodes and the bonding wire inductance, the whole physical structure of FREMP protection module is set up based on Butterworth low pass filter model. A FREMP protection module is realized. The measured insertion loss of protection module is lower than 0.38 dB in 1-250 MHz. At large signal condition with input square wave pulse of 4 000 V, the response time is less than 2 ns and the output level is lower than 30 V, which meets the protection requirement of FREMP. Key
