Abstract :
New microwave (10GHz) transmitter-receiver switch (T/R switch) employing high-Tc, superconductive (HTS) film elements is presented. Its operating principle is based on the fast switching of the film from the superconducting (S) state to the normal conducting (N) state under microwave (MW) pulses. In the 20% band width the device demonstrates the decoupling >30dB between transmitter and receiver at 100W pulse power. The transmission coefficients between transmitter and antenna ~1.5dB and between antenna and receiver less than 1dB.
