Abstract. An ability is demonstrated to create a device protecting from intense radio-pulse on the base of microstrip resonators coupled trough the third one containing HTS element. The device operates as follows. Under radio-pulse action whose intense exceeds a specific threshold the HTS element switches from the superconductive state to the normal one having high resistance, as a sequence, the quality factor of the coupling resonator drops, and the coupling between input and output resonators is destroyed.

Keywords: protector, microstrip resonator, HTS, coupling coefficients, rejection level.
