Abstract
For use with various types of devices conditioning radio signals, a temperature compensating cavity resonator includes a practicable and effective assembly. The resonator includes: a cavity resonator housing having an enclosing plate for enclosing the housing at a top edge, a base, and a surrounding wall extending from the top edge to the base; first and second opposing retainers located below the top edge and at the surrounding wall; a central post having a base end supported by the base of the housing and having a free end surface directed toward the top edge of the housing; and a temperature-compensating metal-based plate assembly including an upper strip extending from the first opposing retainer to the second opposing retainer and at a distance below the top edge, and including a lower strip having ends meeting the upper strip and having a center portion arranged over the free end surface and at a distance from the upper strip that varies in response to temperature to maintain a desired effect on energy passing through the cavity resonator housing.
