Theory of Mutually-Synchronized Gunn Oscillator acting as FM Detector

Abstract

This paper presents the theory of a mutually-synchronized Gunn osciallator system which acts as a microwave FM detector. The theory predicts that the Gunn oscillator system can detect microwave FM signals over a narrow bandwidth with high frequency sensitivity.

Indexing terms:

• Gunn oscillator
• Mutual synchronization
• FM detector
• Bandwidth
