ABSTRACT:
This microwave oscillator in one embodiment has two tuning rods (16 and 18) configured to extend within a resonant cavity (12). One of these tuning rods (18) attaches to a shaft (19) that is affixed at one end and that is comprised of a material having a thermal coefficient of expansion that is different from the material comprising the housing (11) that forms the cavity (12). As a result, movement of the tuning rods (16 and 18) will vary as temperature varies, with a resulting stability in the frequency of oscillation.
