Problems solved by technology

[0002] At present, the repeater mainly uses a single frequency band and a single system. When using multi-frequency transmission, the traditional method is to use multiple repeaters in combination; using multiple repeaters is costly; adding combined channels reduce the power to the antenna; increase the difficulty of engineering installation; increase the consumption of electric energy

Abstract

The invention relates to the technical field of mobile signal transmission and specifically provides a novel combined type repeater. A WCDMA 2100 circuit consists of a first low noise amplifier, a first intermediate frequency filter, a first power amplifier, a second low noise amplifier, a second intermediate frequency filter, a second power amplifier and a phase lock loop PLL, wherein the first low noise amplifier, the first intermediate frequency filter and the first power amplifier are connected to a first quadplexer and a second quadplexer successively in series; the second low noise amplifier, the second intermediate frequency filter and the second power amplifier are connected to the first quadplexer and the second quadplexer successively in series; the phase lock loop PLL is connected between the first intermediate frequency filter and the second intermediate frequency filter. A broadband antenna serves as a main antenna and is connected to the repeater to achieve signal coverage of different frequencies; the requirements for sites in engineering installation are reduced, the cost of whole engineering is reduced and the equipment cost is reduced; the energy consumption of the whole system is reduced; the coverage of the same district at different frequency bands by the same service provider can be achieved and the signal coverage of the same district by different service providers can also be achieved.

Description

technical field [0001] The invention relates to the technical field of mobile signal transmission, in particular to a novel combined repeater. Background technique [0002] At present, the repeater mainly uses a single frequency band and a single system. When using multi-frequency transmission, the traditional method is to use multiple repeaters in combination; using multiple repeaters is costly; adding combined channels The device reduces the power to the antenna; increases the difficulty of engineering installation; increases the consumption of electric energy. Contents of the invention [0003] The purpose of the present invention is to provide a new type of combined repeater, which uses a broadband antenna as the main antenna, which can achieve signal coverage of different frequencies when connected to the repeater; meanwhile, it also reduces the requirements for the site during engineering installation. Reduce the cost of the entire project, reduce equipment costs; r...
