Abstract
The work aims to design a strong EMP protection module for L-band RF front-end sensitive devices and carry out a joint simulation design with transient voltage suppression diodes,gas discharge tubes and hairpin microstrip bandpass fil-ters.The transient voltage suppression diode had a fast response time,the gas discharge tube had a high power capacity,and the microstrip bandpass filter separated the noise signal and retained the active signal.By combining these devices in the protection design,their respective advantages were fully utilized to improve system stability and provide strong EMP protection.Through the design,the module worked in the frequency band of 1.3～1.7 GHz,the insertion loss was less than 1.5 dB in the working band,and the protection effect reached 42.5 dB under 70 dBm power injection,which indicated a good protection effect.By analyzing the characteristics of various devices and optimizing the design,the study achieves the protection of the L-band spec-trum,which has important practical value and broad application prospects.
