Abstract
Abstract The present invention relates to microwave circuits for operating on microwave radiations. It consists in combining a dielectric resonator and a microwave diode in a hybrid or integrated circuit, in order to provide a circuit which will operate without any external elements other than a direct current supply for the transmitter and a local microwave radiation for the receiver.
