发明名称 CAVITY FILTER, AND REMOTE RADIO DEVICE, SIGNAL TRANSCEIVING APPARATUS, AND TOWER MOUNTED AMPLIFIER HAVING CAVITY FILTER
摘要 Disclosed are a cavity filter, and a remote radio device, a signal transceiving apparatus, and a tower mounted amplifier having the cavity filter. The cavity filter comprises a cavity, a cover plate, and a connector disposed on the cavity or the cover plate. The cavity is sealed and covered by the cover plate to form a plurality of cascaded resonant cavities, and the plurality of cascaded resonant cavities are separated by separation ribs disposed on the cavity or the cover plate. At least two resonant cavities are provided with a resonant column in the shape of a solid column, and one end of the resonant column is integrally formed with the bottom wall of the cover plate or the cavity. The cavity filter further comprises a connecting member, and the resonant column is electrically connected to the connector by means of the connecting member. The connecting member comprises a tap and a capacitor loading disc that are integrally formed, the tap is connected to the connector, and the capacitor loading disc is detachably connected to the end surface of the other end of the resonant column. The cavity filter of the present invention has relatively low manufacturing costs and can effectively avoid noise generation.
