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
