RESONATOR MANUFACTURING METHOD FOR RF FILTER AND RF FILTER WITH THE RESONATOR

摘要

Disclosed are a method for manufacturing a resonator of an RF filter and an RF filter with the resonator. The disclosed method comprises: a step (a) for preparing a pipe which is capable of being commercially obtained; a step (b) for cutting the pipe at a predetermined length; and a step (c) for coupling the cut pipe at the predetermined length to the bottom of the RF filter using a resonator. According to the disclosed method, cost and time for manufacture of the resonator for the RF cavity filter are reduced without loss of raw materials.
