Problems solved by technology

[0004] The purpose of the present invention is to provide an active antenna for mobile communication and the distributed antenna system formed thereof, which mainly solves the problem in the prior art that the power loss is relatively large due to the fact that most DAS systems use passive antennas, and the application effect decreases with time. Coverage increases and decreases, which is not conducive to the promotion and application of the problem

Abstract

The invention discloses mobile communication active antennas and a distributed antenna system with the same, and mainly solves the problems as follows: in the prior art, power loss is more because most conventional DASs (Distributed Antenna Systems) adopt passive antennas; the application effects of passive antennas decline with the increase of the coverage; passive antennas are difficult to popularize and apply. Each mobile communication active antenna comprises a first duplexer, a downlink amplifying module, a downlink filtering module, a downlink power amplifying module, a second duplexer, an uplink low-noise amplifying module, an uplink filtering module and an uplink power amplifying module which are connected clockwise into a cyclic structure. Through the adoption of the scheme, the purposes that the power consumption is lower and the coverage is wider are achieved. Therefore, the mobile communication active antennas have high utility values and popularization values.

Description

technical field [0001] The present invention relates to an active antenna, in particular to an active antenna for mobile communication and a distributed antenna system formed thereof. Background technique [0002] Distributed Antenna System (DAS: Distributed Antenna System) is a network composed of multiple antennas distributed in a building and dedicated to providing wireless indoor coverage. [0003] Compared with other systems, the DAS system has many advantages, such as: the initial investment of the DAS system is lower, and the reliability is higher; with the advent of the 3G era, as a broadband system, the DAS solution is very suitable for multi-operators and multi- Business system use, including all types of wireless services, such as trunking mobile communication systems, cellular systems, and wireless local area networks (WLANs) with rates up to 2.5GHz; due to different buildings, each area has different requirements for wireless broadband coverage The difference i...
