Design of a compact UWB Wilkinson power divider

Abstract

In this paper, a Wilkinson power divider operating over an ultra wide frequency band (3.1 to 10.6 GHz) is presented. The proposed power divider consists of two branches of impedance transformer, each of which consists of two sections of transmission line with different characteristic impedance and different length. And a resistor is set between the two sections. The simulated and experimental results of the developed divider are presented and show good agreement.
