  • Microwave oscillator having feedback coupled through a dielectric resonator
    Patent number: 4079341
    Abstract: An apparatus for stabilizing microwave oscillator circuits is disclosed. The apparatus comprises a dielectric resonator positioned in the vicinity of a microwave semiconductive device for completing a feedback path between two electrode circuits of the device. A dielectric spacer is positioned between the resonator and the electrodes for supporting the resonator and controlling the magnitude of coupling between the two electrode circuits. A folded mechanical structure is described wherein the oscillating device and the resonator are located at the fold for improving the frequency stability of the oscillator. The microwave semiconductive device may be a bipolar transistor or a field effect transistor.
