Modified design of Wilkinson power divider for harmonic suppression

Abstract

A modified design that can reject the nth harmonic output in the Wilkinson power divider is presented. After adding transmission lines between the resistor and each output port of the traditional design, a solution of the modified Wilkinson divider can be found. Experimental results show the third harmonic suppression to be -37.0 dB, while maintaining conventional performance at the fundamental frequency.
