Abstract:
This paper presents the design of a novel dual-band unequal Wilkinson power divider. The proposed power divider can operate at arbitrary two frequencies without reactive components. The design and analysis of power divider are presented. The structure of the power divider and the formulas used to determine the design parameters have been given. Closed-form design equations are derived based on network theory. For verification, a microwave power divider operating at 1 and 2 GHz is fabricated, the experimental results show that the designed unequal power divider fulfills all the features of a conventional Wilkinson power divider.
