Abstract
A switchable microwave oscillator is disclosed that includes a quenching circuit for switching, attenuating, modulating, or otherwise controlling the output amplitude of frequency-stabilized, transistor-based, microwave-frequency oscillators. The quenching circuit includes a diode that is coupled to the transistor at the same port that reactive feedback is present, and includes diode biasing means for selectively applying a bias voltage to the diode. The quenching circuit selectively diverts some of the current flowing through the transistor of the oscillator to control the output thereof.
