Özet

A planar circuit realization of a frequency discriminator based on single-mode operation of the dielectric resonator is presented. Drawing on the phase-shifting action of the dielectric resonator, the discriminator function can be achieved with one detector diode, thus adding to the simplicity of the design. It is demonstrated with measurements on the performance of discriminators implemented with dielectric resonators having different temperature coefficients that effective frequency stabilization by thermal compensation for the substrate material can be facilitated by the additional degree of freedom brought about by the dielectric resonator.
