Title (EN) TEMPERATURE COMPENSATED MICROWAVE RESONATOR
(FR) RESONATEUR A MICRO-ONDES COMPENSE EN TEMPERATURE
Abstract:
(EN) A microwave resonator which includes a temperature-compensating structure (26) within the resonator cavity (12a) configured to undergo temperature-induced dimensional changes which substantially minimize the resonant frequency change otherwise caused by temperature-induced dimensional changes in the waveguide body cavity. The temperature-compensating structure includes both bowed and cantilevered structures on the cavity endwall (13), as well as structures on the cavity sidewall (11) such as a tuning screw of temperature-responsive varying diameter.
(FR) Résonateur à micro-ondes comprenant une structure à comprensation de température à l'intérieur de la cavité du résonateur, configurée pour subir des changements dimensionnels induits par la température et qui réduit pratiquement au minimum la variation de la fréquence de résonance provoquée autrement par les changements dimensionnels induits par la température dans la cavité du corps du guide d'onde. La structure à compensation de température comprend des structures aussi bien arquées qu'à cantilever sur la paroi extrême de la cavité, ainsi que des structures sur la paroi latérale de la cavité, telle qu'une vis d'accord d'un diamètre variable en fonction de la température.
