Title:
PHASE BALANCING UNIT AND POWER DIVIDER CIRCUIT PHASE BALANCING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/094988
Kind Code:
A1
Abstract:
Provided in the present invention is a phase balancing unit, comprising 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 branch circuits connected to the main circuit and connected to the output ports on a one-to-one basis, at least one output branch circuit being provided with a coupling transmission wire for modifying signal phases. By means of arranging a coupling transmission wire on at least one output branch circuit of the power divider circuit, the present invention changes the phase delay length of different frequency bands, and thereby achieves the objective of improving the phase dispersion of the input port to each output port in certain frequency bands. Also provided is a power divider circuit phase balancing apparatus employing the present phase balancing unit.
