Problems solved by technology

However, increasing the number of phase shifters will result in a multiplied increase in the output and output ends of the phase shifter, which will result in an increase in the occupied space, thereby increasing the size of the entire antenna, and ultimately increasing the difficulty of the layout of the feed network

Embodiment Construction

[0021] The phase shifting device of the present invention includes a housing and at least one multi-channel phase shifter set arranged in the housing, which will be described in detail below with reference to the accompanying drawings.

[0022] refer to figure 1 , the phase shifting device according to the first embodiment of the present invention includes a set of multi-channel phase shifters arranged in the casing, and the multi-channel phase shifter includes N+1 phase shifters, wherein N is an integer, and every two phase shifters A power divider is combined between adjacent phase shifters, and then there are N power dividers in total, the phase shifter is abbreviated as ps, and the power divider is abbreviated as pd. Here, the input port port1 of the phase shifter ps1 is used as the input end of the phase shifting device, the port port2 is used as the output end of the phase shifter ps1 to be connected to the port port3 of the power divider pd1, and the port port3 is used ...

Abstract

A phase shifting device, comprising a casing (501, 502, 601, 701, 804), and at least one set of multi-channel phase shifters (601, 602, 801, 802, 901, 902) arranged in the casing, capable of Realize multi-channel output and larger phase shift. This kind of phase shifter has a more compact structure and more stable performance. Moreover, the number of phase shifters can be flexibly selected to meet the characteristics of broadband and the demand for multiple phase shifts. .

Description

technical field [0001] The present invention relates to a mobile communication system, in particular to a phase shifting device. Background technique [0002] With the rapid development of mobile communications, the requirements for electrical and mechanical properties of base station antennas are getting higher and higher. High-performance and miniaturized devices are gradually becoming a development trend, such as larger electrical downtilt, higher efficiency, wider frequency band, and more compact structure. Phase shifters are key components in the feed network. Often, multiple outputs and higher phase shifts are achieved by adding multiple phase shifters to the original design. However, increasing the number of phase shifters will double the number of output terminals and output terminals of the phase shifting device, which will increase the occupied space and increase the volume of the entire antenna, which ultimately increases the difficulty of the layout of the feed...
