电视CH4频道与调频频段合成无线发射的技术方案设计

Technical Scheme Design of Wireless Transmission Combining TV CH4 Channel with FM Band

本文介绍了一种全新的,可以实现电视CH4频道与调频频段发射机输出功率信号互不干扰的合成后,使用同一套宽频带天馈系统进行无线发射的技术方案。相比传统的分系统发射技术方案,本技术方案具有节省塔顶空间、增加天线增益、节省建设投资、提升系统安全性和可靠性等突出优势。

A novel technical proposal is introduced in this paper,which can realize output power combination of TV channel 4 and FM band transmitters without mutual interference,and use the same set of broadband antenna feed system for wireless transmission.Compared with traditional independent sub-system transmission technology,this technical proposal has outstanding advantages of saving tower top space,increasing antenna gain,saving construction investment,improving system security and reliability,etc.
