Abstract

本发明涉及到通讯的技术领域，公开了一种组合移相器及多频天线网络系统。该组合移相器包括至少两个层叠的移相器，且每个移相器的频段不同，其中，每个移相器包括信号层以及可相对所述信号层滑动并用于改变所述信号层的输出端的相位的部件，其中，所述信号层的输出端设置有滤波电路；至少两个移相器对应的滤波电路的输出端通过导体连通，并通过一个公共输出端输出。在本发明的技术方案中，通过采用导体将两个不同频率的移相器的输出端整合到一起输出，在此，便于整机布局，减少了多频天线网络系统中的线缆的使用，便于布局，从而方便了多频天线网络系统的设置，此外，便于整机布局，减轻整机重量，节约成本。此外，本发明实施例提供的组合移相器还可以提高天线增益，优化方向图参数。
