文章主要从理论上分析了移动通信信号通过有线电视共缆传输实现室内覆盖分布系统的可行性,利用低温共烧陶瓷器件实现了宽带合路器和无源分路终端两个关键部件的研制。首先,文章对共缆传输进行了简要的概述,继而分别从对信号传输损耗问题的分析、对有关宽带合路器以及对无源分路终端的设置问题的分析三个角度对文章的主旨进行了阐述,最后,文章又提出了一系列需要注意的问题,希望能够为相应领域以及有关人员提供参考,从而在提高有线共缆传输的可靠性以及有效性的基础上,扩大其室内覆盖范围,以实现移动覆盖。
The article mainly analyzes the feasibility of the mobile communication signal to realize the indoor coverage distribution system through the cable television transmission in theory. The development of two key components of the broadband combiner and the passive shunt terminal is realized by the low temperature co-fired ceramic device. First of all, the paper gives a brief overview of the transmission of the coax cable. Then, from the analysis of the signal transmission loss problem, the thesis mainly analyzes the problems of the broadband combiner and the setting problem of the passive branch terminal Finally, the article also put forward a series of issues needing attention, hoping to provide reference for the corresponding areas and related personnel, so as to improve the reliability and effectiveness of the cable based on the cable to expand its indoor coverage, To achieve mobile coverage.
