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.
Claims10
A microwave circuit for radiating microwave radiations, which comprises:
- an electrically conductive substrate for reflecting said microwave radiations;
- a dielectric resonator made of semiconductor material and mounted on said substrate;
- a semiconductor oscillator diode fitted with two connections, lying above said substrate and being a structure integrated onto the face of said resonator adjacent to said substrate;
- and
- means for coupling said diode to said resonator, and simultaneously connecting the diode to an external biasing source.
