ABSTRACT:
A device comprises a microwave resonator having at least one cavity having a predefined resonant frequency. The device also comprises a temperature compensation system that is made from a material having a coefficient of thermal expansion that is very low compared to that of the material from which the cavity is made and includes a structure for counteracting the effects of temperature variations on the resonator so that the resonant frequency of the cavity remains within a predetermined range. The device further comprises a temperature compensation adjustment device adapted to modify the volume of the cavity to adjust the value of the resonant frequency to a predefined value. The cavity comprises a cylindrical wall having a longitudinal axis and two opposite ends, one of which is blocked by a deformable cap, and the temperature compensation system and the temperature compensation adjustment device are coupled to each other and to the resonator so as to exert forces on the cap of the cavity along an axis corresponding to the longitudinal axis of the cavity.
