The present invention relates to a tunable waveguide resonator and a method of tuning a frequency of the tunable waveguide resonator. The waveguide resonator comprises a waveguide part having a plurality of walls where one of the plurality of walls at least partly comprises a tuning element. The tuning element has a first main surface facing toward a first main surface of an inner wall of one other wall of the plurality of walls. The tuning element is caused to, in response to a change in a temperature of the tuning element be reversibly displaced with respect to a reference plane of the first main surface of the tuning element along an extension perpendicular to the first main surface of the one other inner wall and whereby changing a dimension of a cavity of the tunable wave-guide resonator.
