Transmission module, transmission system and base station antenna

Abstract

The invention discloses a transmission module, transmission system and a base station antenna. The transmission module includes a mounting bracket; a first transmission unit assembled on the mounting bracket for driving a phase shifter to displace, and provided with a first transmission interface for external connection to a drive source; a mark ruler telescopic mechanism assembled on the mounting bracket for measuring the displacement of the phase shifter and composed of a second transmission unit, a mark ruler and an elastic member. The second transmission unit is provided with a second transmission interface and can be synchronized with the movement of the first transmission unit through the cooperation between the second transmission interface and the first transmission interface. The mark ruler is positioned through the second transmission unit. One end of the elastic member is connected with the mounting bracket, and the other end of the elastic member is connected with the mark ruler so that the mark ruler can shrink in the mounting bracket. Through the above manner, the invention can well protect the mark ruler so as to facilitate the adjustment of the phase shifter, and the invention has a simple and compact structure and can improve the transmission accuracy.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a transmission module, a transmission system and a base station antenna. Background technique [0002] The mobile communication system is a combination of wired and wireless. It is a complex in which the mobile network connects the mobile station with the base station through the air interface (antenna) within its coverage area, and then connects with the mobile switch. Therefore, the antenna is very important for mobile communication. For the network, it plays a decisive role. If the antenna selection (type, location) is not good or the antenna parameters are not set properly, it will directly affect the operation quality of the entire mobile communication network. Especially in areas with a large number of base stations, small station distances, and high traffic areas with a large number of carrier frequencies, coupled with the multiple reflections and occlusions o...

Problems solved by technology

[0004] However, there are many deficiencies in the prior art methods for the design of the transmission system. The RCU module of the existing transmission system is usually designed outside the electronically adjustable antenna. This design not only greatly increases the occupied space outside the antenna, but also does not work well. Therefore, the existing transmission system has complex structure, large space occupation and low transmission accuracy

[0005] In addition, the scales of most existing transmission systems are fixedly connected to the transmission module, and the scales are exposed outside the antenna for a long time, and are prone to damage and failure in harsh environments
