Description
Summary:ABSTRACT In this article, we suggest a new design method of the unequal Wilkinson power divider. The line impedances of the proposed formula are decided after the resistor value is arbitrarily chosen, while the isolation resistor of the conventional unequal Wilkinson power divider is derived by the power ratio. Therefore, using the proposed formula, the more accurate resistor value is applicable to the Wilkinson power divider, and a narrow line width is improved up to 46.5% in 10:1 Wilkinson power divider. The proposed design formula of the Wilkinson power divider is derived, and the proposed formula is verified by the fabrication and measurement results. © 2016 Wiley Periodicals, Inc.
