Abstract

The invention provides a phase balancing unit. The phase balancing unit comprises an input port, a plurality of output ports and a power divider circuit; the power divider circuit comprises a main circuit connected to the input port and a plurality of output branches which are connected to the main circuit and are connected to the output ports in one-to-one correspondence; and at least one output branch is provided with a coupling transmission line for changing a signal phase. The coupling transmission line is arranged on at least one output branch of the power divider circuit, which changes phase delay lengths of different frequency bands and achieves a goal that phase discrete type from the input port to each output port is improved in a certain frequency band phase. Besides, the invention also relates to a power divider circuit phase balancing device adopting the phase balancing unit.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a phase balance unit and a power divider circuit phase balance device using the phase balance unit. Background technique [0002] In the mobile communication network coverage, the base station antenna is one of the key equipment of the coverage network. The main function of the base station antenna is signal coverage, and the pattern index to achieve signal coverage is particularly important. [0003] In base station antennas, base station antennas are divided into electrically adjustable base station antennas and non-electrically adjustable base station antennas. However, regardless of whether the base station antenna can be adjusted electrically, a power splitter is required, and the difference between them is only that the phase is adjustable or not. [0004] In addition, in a distributed circuit, the ratio of the size of the circuit to the working wavelength is basically ...
