Design of a Novel Three-way Tri-band Power Divider

摘要

A three-way triple-band equal-split power divider is analyzed and designed in this paper. The topology of the circuit is six sections of three transmission lines and planar isolation resistors, which provides high isolation and good amplitude balance simultaneously at three arbitrary frequencies. The structure of the power divider and the formulas used to determine design parameters are presented. To demonstrate the design methodology, a 900/1800/2400 MHz power divider is realized. Good performances of the proposed power divider at three frequencies are obtained.
