Abstract
A mutually synchronized Gunn oscillator system acting as a FM detector has been demonstrated. The frequency sensitivity of this detector has been found to be much higher than that of a single injection locked oscillator acting as a FM-AM converter. High index FM signals can be faithfully detected in this detector.
