Title: BRANCHING TOWER AMPLIFIER AND ANTENNA FEED SYSTEM
Abstract:
The present invention relates to the field of communications; provided in an embodiment thereof are a branching tower amplifier and an antenna feed system, which, by means of adding a branching tower amplifier at the side of an antenna unit, may ensure the coverage of a network and enhance performance of the network while achieving the functions of RRUs of four ports. The branching tower amplifier comprises: a first filter module, a second filter module, a first amplifier module, a second amplifier module, a control module, a first branching module and a second branching module, wherein the first filter module is connected with the first amplifier module, the first amplifier module is connected with the control module, the control module is connected with the second amplifier module, and the second amplifier module is connected with the second filter module. Comprised are the first branching module which is connected with both the first filter module and the first amplifying module, and the second branching module which is connected with both the second filter module and the second amplifying module, wherein the first branching module and the second branching module are both used for transmitting signals.
