ABSTRACT:
A circuit is described in combination with a dielectric-resonator-stabilized oscillator operating at microwave frequencies in which a PIN diode serves to shunt the reflected output signal of the stabilizing resonator from the input of the oscillator circuit into a load to turn the oscillator off. By biasing the diode in a reverse or forward direction, the oscillator is made to start or stop oscillating, respectively. This has the effect of switching the output of the oscillator on and off while eliminating thermal transients associated with de-energizing the active element of the oscillator circuit itself, or the necessity for inefficient microwave switches which may pass some signal through.
