1、前言
双向塔顶放大器是是一种将原来基站的上下行信号同时进行放大的设备。安装在塔顶部紧靠在接收天线之后的一个低噪声放大器。在接收信号进入馈线之前可将接收信号放大近 12dB，提高上行链路信号质量，改善通话可靠性和话音质量，同时扩大小区覆盖面积。当用户位于小区覆盖范围之外，有可能掉话时，采用塔顶放大器是十分有利的。目前的应用是将塔顶放大器和功率放大器组合形成覆盖延伸系统。
2、方案概述
Ameya360 双向塔顶放大器解决方案所采用的放大模式是对基站的每个载波单独进行放大（即对基站的每一载波的 TX/RX 进行放大），由于基站的信号是通过合路后输出的信号。以一个两载波的小区为例，两个载波的下行信号通过合路后通过天馈线进行发射，如果不增加信号分配单元，则无法保证该小区的每个载波都可以放大到 80W。双向塔顶放大器设备对二载波小区中的二个载频分别进行单独放大，所以我们要对基站主设备的输出信号进行重新分配，使得基站的下行号不经过基站主设备的合路器部分，而是在下行信号未进入合路前，把载波的下行信号单独抽出来，进入我公司的信号分配单元的下行输入口，上行 2 路 RX 信号仍使用基站合路器的两根 1/2 跳线。
