ABSTRACT:
In a voltage controlled oscillator, a dielectric resonator is mounted on a base of a conductive housing, and a dielectric substrate is secured to sidewalls of the housing in a position spaced from the dielectric resonator. A first stripline is secured to one surface of the substrate and electromagnetically coupled to the dielectric resonator, and an oscillating element is electrically connected to the first stripline. A second stripline is secured to the opposite surface of the substrate and capacitively coupled to the first stripline through the substrate. The second stripline is adapted to receive a frequency control voltage from an external circuit. A voltage-controlled variable capacitance element is secured to the substrate and electrically connected to the second stripline.
