Abstract

The invention discloses a passive broadband combiner which fully utilizes an existing 2G and 3G network distribution system, is high in signal isolation, wide in coverage range and convenient to construct, saves cost and achieves complete coverage of 2G, 3G and 4G network signals. The passive broadband combiner comprises four duplexers (1, 2, 3 and 4), six bridges (31, 32, 33, 34, 35 and 36) connected with the uplink output ends and the downlink output ends of the duplexers (1, 2, 3 and 4), four three-in-one combiners (41, 42, 43 and 44) connected with the output ends of the six bridges (31, 32, 33, 34, 35 and 36), and four loads (R1, R2, R3 and R4) connected with the other input end of each of the bridges (31, 33, 34, and 36), wherein a GSM signal source, a DCS signal source, a LTE-FDD signal source and a WCDMA signal source are respectively connected to the four duplexers (1, 2, 3 and 4), two downlink ports (Tx1 and Tx2) and two uplink ports (Rx1 and Rx2) are respectively led out of the output ends of the four three-in-one combiners (41, 42, 43 and 44) to be connected with the distribution system. The passive broadband combiner can be widely applied to the field of mobile communication.

Description

technical field [0001] The invention relates to a passive broadband combiner. Background technique [0002] LTE (Long Term Evolution, Long Term Evolution) is a new generation of mobile network technology standards led by 3GPP (The 3rd Generation Partnership Project, Third Generation Partnership Project), which improves and enhances 3G air access technology, and its network structure further Flattening is regarded as the mainstream technology in the evolution from 3G to 4G. The advantage of LTE network is that it can better provide high-speed data services. The development law of 3G services at home and abroad shows that 70% of high-speed data services occur in indoor environments. As the main way to solve indoor coverage, the construction of LTE indoor distribution system has become The top priority of LTE network construction. [0003] In the construction of the existing indoor distribution system, the 2G and 3G networks share the antenna feeder system. If a new LTE netw...
