RF RF Cavity Filter Using Elastic Body and Method for Producing the Same

摘要

An RF cavity filter is disclosed. The disclosed filter comprises: a housing in which at least one cavity is formed; A cover coupled to the upper portion of the housing; At least one bolt inserted through at least one through hole formed in the cover; And at least one elastic body joined to the cover in a lower region of the through hole, wherein the bolt is inserted through the through hole to provide an external force to the elastic body, and the shape of the elastic body is changed by the external force. According to the disclosed filter, it is possible to prevent the small metal debris generated during tuning from falling into the filter, deteriorate the PIMD characteristic, fix the tuning state without using a separate nut, and satisfy the PIMD requirement It is possible to improve the production yield of the filter.
