This paper presents the theory and experiment of a hybrid microwave FM discriminator that operates on the combined principles of an active and a passive microwave discriminator. This discriminator implemented from passive waveguide components and a Gunn oscillator is found to have a bandwidth equal to the lockband of the Gunn oscillator and frequency sensitivity greater than that of an active discriminator. The overall figure of merit of this discriminator is greater than that of a passive and an active microwave discriminator.
