描述

頻段幹線放大器(線路放大器)旨在提供比添加新基站收發器 (BTS) RF Repeater更具成本效益的解決方案,以擴展信號覆蓋範圍並改善通信DAS 系統的質量。其易於安裝和維護,可以幫助營運商快速獲得回報。中繼放大器用作 BTS  RF Repeater與分佈式天線之間的中繼。它通過耦合器接收來自室內分配系統幹線的低功率信號,將信號線性放大,然後通過電纜將其重新傳輸到天線分配系統。並且移動信號也被放大並通過相反的方向重傳到BTS

The Triple-Band Trunk Amplifier (Line Amplifier) is designed to provide a more cost-effective solution than adding a new Base Transceiver Station (BTS) or RF Repeater to extend signal coverage and to improve communication quality in DAS system. And its easy installation and maintenance can help carrier get fast return. The Trunk Amplifier is working as a relay between the BTS or RF Repeater and distributed antennas. It receives the low-power signal from Trunk line of indoor distribution system via the coupler, linearly amplifies the signal and then retransmits it via the cables to the antenna distribution system. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.
