Abstract
A multifunction high frequency integrated circuit structure and circuit configuration includes a resonator or oscillator circuit coupled to a buffer amplifier by way of a stripline coupler. The resonator circuit includes an input terminating region which is coupled to three input terminating ports. A first one of the input terminating ports is coupled directly to the resonator for either being electrically connected to a selected signal source or load, a second one of the input terminating ports is electrically connected to either a fixed or variable potential source, and the remaining input terminating port is coupled to the resonator input terminating region through another stripline coupler, and is intended to be electrically connected to another selected signal source. Depending upon the choice of circuit components and signal sources connected to the input terminating ports, the multifunction high frequency integrated circuit may serve as a voltage controlled oscillator, low phase noise oscillator, direct up/down frequency signal converter, or injection locked oscillator.
