Miniaturized 4-way power divider with 45° phase differences between output ports

摘要

This paper presents a miniaturized 4-way power divider with 45° phase differences between output ports. The divider is developed by combining a 90° Lange coupler and broadband 45° power dividers, and is implemented on an FR4 substrate. The measurement results reveal the feasibility of the proposed power divider configuration for effectively reducing transmitter intermodulation.
