An electromagnetic pulse protection circuit having wave filtering functions, composed of an inductor free slow response protection circuit and a fast response protection circuit, and a filter is series-connected on a signal transmission route, and is utilized to provide impedance in effectively preventing electromagnetic pulses caused by lightning (LS) or other electronic weapon (NEMP, HEMP, PEMP) interferences. In addition, it is capable of suppressing electromagnetic pulses at specific frequencies, thus, raising the capability of electronic elements in resisting against electromagnetic pulses. Furthermore, said filter is made of high-temperature-super-conduction (HTSC) material, so that when said HTSC material of said filter is subject to a sudden infusion or invasion of said electromagnetic pulses, it is switched to a high impedance state in a very short period of time in effectively restricting currents passing through said filter, hereby avoiding the damages of a communication system.
