PIMD RF RF RF Cavity Filter Robust to Degradation Due to PIMD and Method for Producing the Same

摘要

RF cavity filters and RF cavity filter fabrication methods that are robust against performance degradation due to PIMD are provided. The disclosed method comprises the steps of (a) manufacturing a housing and a cover of an RF cavity filter; Applying external force to the cover to form at least one groove; (C) placing at least one plate elastomer in each of said at least one groove; (D) forming a locking projection protruding from the side wall part by applying an external force to the side wall part of the groove in a state where the plate elastic body is located; And (e) performing a soldering coupling to the at least one plate elastic body located in the at least one groove in the step (c) after the locking step is formed. According to the disclosed filter and method, small metal debris generated during tuning can fall into the filter and prevent performance degradation due to PIMD, and it is possible to fix the tuning state without using a separate nut. have.
