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 ...
