ABSTRACT:
A microwave metallic cavity, whose resonating frequency is stabilized versus operating temperature variations. Stabilization is achieved by implementing the cavity with a conical base having a thickness and a coefficient of linear expansion smaller than that of the cavity cylindrical body. In this way the volume enclosed by the conical base to in inverse ratio versus operating temperature variations, so as to compensate for the variation in volume of the cavity cylindrical body, which results in stabilization of the resonating frequency.
