  • Quartz microstrip gunn oscillator
    Patent number: 4890074
    Abstract: A microwave microstrip oscillator includes a thin dielectric substrate, a Gunn diode mounted within the thickness of the substrate, an annular conductive resonator lying on the surface of the substrate and at least partially surrounding the Gunn diode, and a varactor diode associated with the Gunn diode for controlling the frequency of oscillation of the Gunn diode. A microstrip circuit coupled to the Gunn diode extracts an output power signal at a desired microwave frequency.
