ABSTRACT:
A cavity resonator having temperature compensation which comprises a pot and a cover, which together enclose a cavity resonance volume. The pot comprises a first material, which has a first temperature expansion coefficient and the cover comprises a second material, which has a second temperature expansion coefficient. The second temperature expansion coefficient is greater than the first temperature expansion coefficient, and an expansion of the pot and a deformation of the cover results upon a temperature increase, which each independently and also together cause an enlargement of the cavity resonance volume. Simultaneously, the resonance frequency remains essentially constant.
