Abstract
A temperature compensated dielectric resonator device is composed of a dielectric resonator element mounted on a micro-integrated circuit (MIC) plane. A screw is provided for manually regulating the frequency of the device and a supporting member supporting the screw is disposed in vicinity of the element. The supporting member dimensions and materials are predetermined, so that the screw may be held at such a position that it compensates for a resonant frequency shift caused by thermal expansion.
