ABSTRACT:
An apparatus and method is disclosed for providing a planar disc resonator oscillator/amplifier which consists of a planar radial disc resonator, a substrate having a hole extending therethrough, a negative impedance device, and a conductor having a predetermined width. The oscillator/amplifier having an external quality factor dependent upon the width of the conductor and upon the distance between the centers of the planar radial disc resonator and the negative impedance device.
