Soon after low-loss ceramic dielectric material with controllable temperature coefficients
was available at reasonable cost, the dielectric resonator became a widely employed
component in microwave circuits, predominately in filters and solid-state oscillators. Even
though it is not very common, in recent years dielectric resonator applications can also be
seen in frequency discriminator circuits. This paper presents a planar circuit realization of a
frequency discriminator based on single-mode TE01δ operation of the dielectric resonator and
a hybrid ring and temperature coefficient measurements for the center frequency of the
discriminator characteristic. The designed circuit has high temperature stability and the
reduction in physical size and cost of manufacturing is substantial when compared to the
waveguide and cavity version. Theoretical analysis and experimental results of the S-curve
characteristics of the designed circuit are also presented.
