RF CAVITY FILTER USING SHAPE VARIANCE OF PLATE ELASTIC BODY AND METHOD FOR PRODUCING SAME

摘要

Disclosed are an RF cavity filter using a shape variance of a plate elastic body and a method for producing the same. The disclosed filter comprises: a housing having at least one cavity; a cover coupled to an upper portion of the housing and having at least one insertion portion; at least one plate elastic body coupled to the inside of the insertion portion; a tuning member inserted into the insertion portion while having the at least one plate elastic body coupled thereto, and compressing the plate elastic body; and at least one tuning bolt inserted into a bolt hole formed in the tuning member wherein a hole is formed in a lower portion of the insertion portion, and the tuning bolt is inserted through the bolt hole to provide an external force to the plate elastic body, and accordingly, a shape of the plate elastic body is changed by the external force. According to the disclosed filter, it is possible to prevent a crack from occurring in a coupling structure of the elastic body and the cover, and enable the elastic body and the cover to be stably coupled to each other.;COPYRIGHT KIPO 2019
