摘要： The present invention relates to a radio frequency filter having a cavity structure, comprising: a container which has a hollow inner portion and a cavity that is cut off from the outside, and a resonance element which is placed in the hollow inner portion of the container, wherein the container has a wrinkled structure for adjusting the intervals between a longitudinal front end surface of the resonance element and the inner surfaces of the container facing the longitudinal front end surface using external pressure. Thus, the invention can be further miniaturized and is lightweight, and the design of the invention enables frequency tuning without employing a coupling structure of a tuning screw and a fastening nut, thereby obtaining a convenient and simplified structure.
