Abstract

The invention discloses an LTE combiner. The LTE combiner comprises a chamber (1) and a signal common port (2) arranged in front of the chamber (1). The chamber is separated into a China Telecom CDMA800 band-pass filtering cavity (6), a China Unicom LTE1.8G band-pass filtering cavity (7) and a China Unicom LTE2.1G band-pass filtering cavity (8) through separation ribs. All of the band-pass filtering cavities are communicated with the signal common port (2). The rear end of the chamber (1) is provided with a China Telecom CDMA800 signal input port (3), a China Unicom LTE1.8G signal input port (4) and a China Unicom LTE2.1G signal input port (5) respectively corresponding to the band-pass filtering cavities. Every band-pass filtering cavity is provided with one or more resonant rods and a coupling window (13) is arranged between the adjacent two resonant rods in the same band-pass filtering cavity. The LTE combiner can achieve signal combining and signal splitting of China Unicom LTE1.8G, China Unicom LTE2.1G and China Telecom CDMA800.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an LTE combiner. Background technique [0002] The existing mobile communication network is divided into GSM network, 3G network WLAN network and LTE network according to different frequencies. The development trend of mobile communication network is to jointly build and share site and antenna feeder system, reduce the construction cost of mobile communication network, improve Utilization of mobile communication infrastructure. When multiple networks are to be covered in the same building, it is generally necessary to install their respective receiving devices and transmitting devices, which not only troubles the installation, but also increases the cost. In order to avoid this problem, a combiner is needed. The function of the combiner is Synthesize several different signals into one output. Now with the introduction of LTE technical standards, there are higher re...
