RF cavity filter using elastic element and method for manufacturing the same
An RF cavity filter is disclosed. The disclosed filter includes: a housing in which there is at least one cavity formed; a cover joined to an 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 element attached to the cover in an area below the through hole, where the bolt is inserted through the through hole to provide an external force on the elastic element, and the external force alters the shape of the elastic element. With the disclosed filter, pieces of metal debris created during tuning can be prevented from reaching the inside of the filter, and the degradation in the PIMD performance that would have otherwise occurred due to the pieces of debris can be avoided. Also, the filter can maintain a tuned state without the use of separate nuts.
