Base station rf duplexer, rf module, and rf system

Abstract

The present disclosure relates to telecommunication, and in particular, to a base station Radio Frequency (RF) duplexer, an RF module, and an RF system. A base station RF apparatus provided herein includes: an enclosure, an intermediate RF processing unit, and a duplexer. The enclosure is located on the duplexer; the intermediate RF processing unit is located inside a cavity enclosed by the enclosure and the duplexer, or on the duplexer; a duplexer cavity and a heat dissipation part exist on the surface of the duplexer; the opening of the duplexer cavity is opposite to or against the enclosure; the heat dissipation part is designed to dissipate heat of the intermediate RF processing unit; and the duplexer is integrally molded. The foregoing technical solution requires no external fasteners, reduces the time of production and assembly. In addition, waterproof design and shielding design are not required, and thus improves the reliability.

1 . A base station Radio Frequency (RF) duplexer, comprising a first heat dissipation part formed in one surface of the duplexer, a duplexer cavity formed on the same surface or different surface of the duplexer, wherein the duplexer cavity and the first heat dissipation part are integrally molded. 
     
     
         2 . The base station RF duplexer of the  claim 1 , wherein the duplexer cavity and the first heat dissipation part are located on the different surfaces of the duplexer, a second heat dissipation part is formed at the rear area of the duplexer cavity in the surface which first heat dissipation part located on. 
     
     
         3 . The base station RF duplexer of  claim 1 , wherein the duplexer cavity and the first heat dissipation part are located on the same surface of the duplexer, the duplexer further comprises a cover plate, configured to cover the duplexer cavity to protect elements in the duplexer cavity. 
     
     
         4 . The apparatus of  claim 3 , wherein a plurality of partition walls are defined to partition the duplexer cavity into a plurality of chambers, and a plurality of tuning screws 
     
     
         5 . The apparatus of  claim 4 , wherein the elements in the duplexer cavity comprises a plurality of tuning screws, the plurality of tuning screws are located inside the plurality of chamber to adjust the frequency of the duplexer. 
     
     
         6 . A base station Radio Frequency (RF) apparatus, comprising: an enclosure, an intermediate RF processing unit, and a duplexer according to  claim 1 , wherein, the intermediate RF processing unit is located on the duplexer so that the first heat dissipation part can dissipate heat of the intermediate RF processing unit, the enclosure is assembled on the duplexer to have the intermediate RF processing unit located inside a cavity enclosed by the enclosure and the duplexer. 
     
     
         7 . The apparatus of  claim 6 , wherein a third heat dissipation part is designed on the outer lateral of the enclosure. 
     
     
         8 . The apparatus of  claim 6 , wherein a waterproof or shielding treatment device is located between the enclosure and the duplexer. 
     
     
         9 . A base station Radio Frequency (RF) system, comprising an antenna, and a base station RF apparatus according to  claim 6 , wherein:
 a signal connection is located between the duplexer and the antenna for exchanging signals; and   a signal connection is located between the duplexer and the intermediate RF processing unit for exchanging signals.   
     
     
         10 . The system of  claim 9 , further comprising a Base Band Unit, wherein a signal connection is located between the intermediate RF processing unit and the Base Band Unit for exchanging signals.
