MICROWAVE RESONATOR, METHOD OF PRODUCING SUCH A RESONATOR AND METHOD OF COMPENSATING THE TEMPERATURE COEFFICIENT OF THE RESONANT FREQUENCY OF A MICROWAVE RESONATOR

摘要

The invention concerns a microwave resonator with a resonator chamber and devices projecting thereinto for the coupling in and out of a microwave. The object of the invention is to provide a microwave resonator in which the temperature dependency of the resonant frequency of the microwave resonator is reduced. This object is achieved in that a dielectric body with a negative temperature coefficient is provided in the resonator chamber. Advantageously, superconductive, in particular high-temperature superconductive, material can be used to form at least part of the resonator chamber walls acting as electrical screening.
