UHF选带大功率无线直放站

与添加新的基站收发器（BTS）相比，UHF RF BDA（双向放大器）旨在提供更具成本效益的解决方案，以改善UHF系统中的信号覆盖范围和通信质量。

特点:

铝合金外壳，防护等级达到IP65，可防尘，防水和防腐蚀.
支持所有组合的UHF频段.
采用高增益，低噪声的线性放大器，对基站的干扰小.
采用高选择性和低插入损耗的滤波器消除了上行链路和下行链路之间的干扰.
RJ45端口提供了到笔记本电脑的链接，用于本地监管或基于IP的NMS（网络管理系统），可以远程监管BDA的工作状态，并通过以太网或LAN将操作参数下载到BDA.

应用:

扩大信号覆盖范围或在无线电网络信号较弱或不可用的地方填充信号盲区.
