Abstract: The electromagnetic pulse (EMP) weapons have brought forward a severe challenge to the communication system,especially the radio frequency (RF) front-end circuit.The RF front-end circuit is the key part of the vulnerable link under the strong EMP attack.It is of great significance for the communication system to improve the overall capacity of electromagnetic protection.In this paper,the research content of the EMP protection in the RF front end was analyzed.In terms of three basic elements,namely electromagnetic pulse effect research,electromagnetic pulse protection technology,and electromagnetic compatibility standard,the studies were summarized,including simulation modeling,experimental testing,and protection strategies at home and abroad.Finally,several frontier problems with EMP protection were also summarized,which maybe provide some references for the future researches and applications.
