Abstract: This article presents the design of a novel dual-frequency unequal Wilkinson power divider. This unequal power divider fulfills an arbitrary power split and all the other features of a conventional Wilkinson unequal power divider simultaneously at two arbitrary frequencies. The structure of this power divider and the formulas used to determine the design parameters have been given Both simulated and measured results of the dual-frequency unequal Wilkinson power divider are presented to validate our proposed idea. Good experimental performances of the proposed power divider, including an arbitrary power split and a good isolation between the output ports at both frequencies are obtained. © 2008 Wiley Periodicals, Inc.
