Abstract
The embodiments of the present disclosure disclose a cavity filter. An inner wall of a resonant cavity is provided with a plurality of non-coplanar extension sections inclined toward an outer wall; and meanwhile, each extension section gradually extends toward an end cover from a bottom shell. Thus, a volume of the resonant cavity is increased, making an insertion loss smaller; an outer dimension of the cavity filter is further reduced, making an overall weight lighter; and meanwhile, during casting of a shell portion of the cavity filter, the difficulty of demolding is reduced.
