Abstract

The invention provides a filter. The filter comprises a resonant cavity body, a resonant rod, a tuning screw rod, a resonant cover plate, a connector, a conductor, a port sheet and a mounting base, wherein the connector, the conductor and the port sheet are arranged on the mounting base; two ends of the conductor are vertically connected with the connector and the port sheet; the resonant cavity is a frame structure with an opening in one side; the resonance rod is arranged in the resonance cavity; the resonant cover plate is arranged on the resonant cavity and seals the opening; and the tuning screw rod is arranged on the resonant cover plate and extends into the resonant cavity, an extending boss is arranged on one side of the resonant cavity, a through groove is arranged in a side wallof one side, close to the extending boss, of the resonant cavity, the mounting base is arranged on the extending boss, the port sheet and the resonant rod are electromagnetically coupled through the through groove, and the tuning screw rod and a plugging and unplugging surface of the connector are located on the same side. The tuning screw rod of the filter and the plugging and unplugging surfaceof the connector are located on the same side, and the filter has advantages of good electrical performance, high reliability, a small size and low manufacturing cost.

Description

technical field [0001] The present application belongs to the technical field of communication equipment, and more specifically relates to a filter. Background technique [0002] As a key component of the communication system, the filter is widely used in various mobile communication systems. With the development of the wireless communication industry, the RF communication system has higher and higher requirements for the integration, modularization and integration of the filter, making The size of the filter is getting smaller and smaller, especially the thickness allocated to the filter module by the base station system is limited, so that the thickness of the filter is required to be higher and higher. [0003] When the filter module is connected to the RRU (Remote Radio Unit, remote radio frequency unit), the plug-in interface of the connector connected to the whole machine is on the same side as the tuning screw of the filter, how to realize that the radio frequency sig...
