ABSTRACT:
A microwave oscillator which has a dielectric resonator which has properties which are dependent on the atmospheric humidity and which should be sealed in a hermetically air tight container to eliminate variations in its characteristics. The dielectric resonator is mounted in a hermetically sealed air tight cavity inside a metal housing in which the electrical circuit is mounted and is arranged at a position relative to coupling elements on a film printed circuit board which has a metallized surface on one side thereof.
