Journal on Circuits And Systems 2322–035X 3 2 8 13 RADAR, Wilkinson Power Dividers (WPD), Advanced Design System (ADS) This paper describes the design and simulation of 1:2.1 power dividers using lumped element model at 54 MHz frequency for radar applications using ADS (Advanced Design System) software. Firstly, designing the symmetrical Wilkinson power divider (WPD) that achieves equal-power split at N arbitrary frequencies is introduced. Each quarterwave branch in the conventional Wilkinson divider is replaced by N sections of transmission lines, and the isolation between the output ports is achieved by using N resistors. The design parameters are the characteristic impedances and lengths of the N transmission line sections, and the N isolation resistors. The even–odd modes of analysis are used to derive the design equations. Closed-form expressions, which are suitable for CAD purposes, are derived for the dualband divider. This device provides maximum isolation between ports and also useful for limited bandwidth applications. March - May 2015 Copyright © 2015 i-manager publications.
