ABSTRACT:
A thyristor for switching microwave signals includes semiconductor layers disposed on a substrate. A first surface of the thyristor defines an anode, and a second surface of the thyristor defines a cathode. The semiconductor layers include at least one semi-insulating layer. The thyristor transmits a microwave signal between the anode and the cathode in an ON state and blocks the microwave signal between the anode and the cathode in an OFF state.
