Abstract

The negative resistance oscillator works in the GHz region. The oscillator is based on a dielectric resonator associated with a negative resistance element. The resonator, normally cylindrical, has one metallised end face mounted on an isolating substrate (2) such as alumina or silica. The substrate is laid on one inside surface of an 'L' cross section base (40) which carries on its remaining face a variable capacity diode (50) or varactor, e.g. a Schottky diode, a decoupling capacitance (7) to earth and a second decoupling capacitor (9). Both capacitors are in parallel and spaced by about a quarter wavelength of the oscillator frequency forming a low - pass filters. The positive supply is taken to earth and the negative to one side of the diode.
