Abstract

The invention discloses a novel adjustable resonator which comprises a housing, a fixed internal conductor and a movable resonant frequency adjusting part, wherein the housing comprises a housing wall, a housing bottom and a housing cover; a resonant cavity is formed in the housing; the internal conductor is electrically connected to the housing bottom; the resonant frequency adjusting part comprises a conductive adjusting element, an upper conductive plate and a medium supporting element; the conductive adjusting element is connected with the upper conductive plate, and a main body of the conductive adjusting element is a longitudinal conductive valve rod; the conductive adjusting element can move down, so that the conductive valve rod can be connected with the internal conductor in a matched way. The novel adjustable resonator has the advantages that the resonant frequency adjusting range is wide, the tenability and the mechanical stability are good, the set resonant frequency can remain unchanged, the structure is simple, and the manufacturing cost is relatively low.

Description

technical field [0001] The invention relates to a novel adjustable resonator, which is suitable for the field of electric component design. Background technique [0002] Traditionally, cavity resonators have been used in the field of filter production. The resonant frequency adjustment of a resonator is generally based on the change in capacitance between the inner conductor and the resonator case cover. Metal tuning screws provided in the housing cover are usually used as tuning parts for the resonator. As the tuning screw is turned, its spacing from the resonator's inner conductor changes, thereby changing the capacitance between the inner conductor and the resonator case cover. [0003] However, there are several problems when using tuning screws: the number of filter parts and production steps are increased, thereby increasing the manufacturing cost; Loss; in high-capacity filters, if the tip of the tuning screw is close to the end of the inner conductor, breakage wil...
