Abstract

A resonator for a filter includes a resonator housing, in which a resonator space is formed. The resonator further includes a dielectric arrangement arranged in the resonator space including a first dielectric element and a second dielectric element, the first dielectric element and the second dielectric element being separated from one another in such a way that a gap is formed between them. Both a first thermal expansion coefficient of the first dielectric element and a second thermal expansion coefficient of the second dielectric element are less than a thermal expansion coefficient of the resonator housing. A temperature-related variation of the resonant frequency of the resonator can therefore be compensated for.
