A power limiter is designed with two resonant diaphragms included in an X-range rectangular waveguide. The cross strips made of high-Tc superconductive films placed in the centre of diaphragms can be in superconducting or normal states. The film state is controlled by the microwave power. The S-N transition in the strips causes a change of the transmitted wave attenuation from 0.5 to 25 dB.
