Abstract
A cavity filter is disclosed. The cavity filter includes: a housing in which at least one cavity is formed where the housing has a resonator held in the cavity; a cover joined to an upper portion of the housing; and a pressing member joined to the cover. An insertion area is formed in the cover for receiving the pressing member, where the insertion area includes a thin part that has a smaller thickness than the main body of the cover. The pressing member may be inserted in the insertion area to press the thin part. The pressing member includes an insert part that is inserted in the insertion area, and an elastic member that is joined to a lower portion of the insert part to press the thin part. The cavity filter can provide stable properties as the resonators are joined to the ground in a stable manner.
