Abstract

The present invention provides a cavity filter, a connector, a duplexer and a remote radio device. The cavity filter comprises a cavity, a cover plate, a resonant tube and a connector. The cavity is provided with a connecting hole. The cavity is sealed and covered by the cover plate to form cascaded resonant cavities. The resonant tube is disposed in the resonant cavity. The connector is fixed to the cavity at the connecting hole and is electrically connected to the resonant tube through the connecting hole, and a connecting end surface of the connector is provided with a first surface matching structure. The outer surface of the cavity in contact with the connector is a plane or provided with a second surface matching structure matching the first surface matching structure, and the connector and the cavity filter form a meshing-based close contact by means of the first surface matching structure and the plane or the second surface matching structure. Therefore, the connector and the cavity are tightly connected, the connector and the cavity filter are in effective contact, a connection gap between the connector and the cavity filter is avoided, and smooth signal transmission is guaranteed.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a cavity filter, a connector, a duplexer and remote radio equipment. Background technique [0002] see figure 1 , figure 1 It is a schematic diagram of a partially enlarged structure of a cavity filter in the prior art. [0003] Such as figure 1 As shown, the cavity filter includes a connector 110 and a cavity 120, and the connector 110 and the cavity filter 120 are fastened and connected by locking screws. [0004] The connection surfaces of the connector 110 and the cavity filter 120 are both plane, and it is easy to appear such as figure 1 The tiny gap 115 shown in , the gap 115 will lead to poor contact and poor signal transmission. [0005] When there is a gap 115 in the connection between the connector 110 and the cavity filter 120 , it will be unfavorable to the conduction of current, causing the insertion loss index, intermodulation index or other electrical pe...
