Abstract

The invention relates to the technical field of multi-system combining, in particular to a 5G system 14-frequency integrated multi-system combining platform which comprises 2G, 3G, 4G and 5G system working frequency bands of different operators, and the working frequency range is 698-3700 MHz. The platform comprises a first-stage combination (multi-system combination) part and a second-stage same-frequency combination (bridge) part, the first-stage combination part comprises 14 system frequency bands which are distributed on the front surface and the back surface of the integrated cavity, a common combination port of the primary combining part adopts an ultra-wideband coupling technology, and the coupling working bandwidth is 698-3700MHz; and the signals are combined to a second-stage same-frequency combination (bridge) part through two ultra-wideband common coupling, namely two input ends of a bridge, and then are transmitted to an output end of a common combination platform through a 50-ohm strip line after being combined by the bridge. According to the invention, an integrated structure is adopted, multi-system frequency bands of multiple operators are integrated together, and multi-system and multi-frequency-band ultra-wideband transmission is realized.

Description

technical field [0001] The invention relates to the technical field of microwave radio frequency communication, in particular to a 14-frequency integrated multi-system combination platform of a 5G system. Background technique [0002] At present, the mobile communication system includes many different systems. These systems are set up and operated by different operators, and they can communicate with each other. In some special occasions, simultaneous coverage of multiple systems is required, and the multi-system combination platform It is such a device that integrates multiple communication systems. The multi-system combination platform is mainly used for signal coverage in subways, high-speed rails, large venues and other places. With the popularization of 5G communication, China will usher in the outbreak period of 5G construction, and all operators will increase their investment in 5G construction. At the same time, more and more new high-speed rail, subway and other l...
