Description
I. Objectives
1. To familiarize students with the use Keysight ADS circuit simulator and EM Momentum
simulator.
2. To give students experience in designing a simple passive microwave 3-port circuit.
3. To understand the differences in performance between the different 3-port power dividers.
II. Introduction
In this project, you will be designing three types the power dividers at 1.2GHz; a lumped element
resistive power divider (in circuit simulation), a distributed T-Junction power divider (in EM
simulation), and a distributed Wilkinson power divider (co circuit/EM simulation). When first
designing the T-junction power divider, you will generate an EM/Circuit co-simulation to allow the
build of the Wilkinson Power divider, this will be explained in the theory. You will then measure a
pre-made 4-way Wilkinson Power divider and record some observations. Once complete, make sure
you answer the discussion questions.
III. Theory
A power divider is a three-port microwave device that is used for power division or power
combining. In an ideal power divider, the power given in port 1 is equally split between the two
output ports for power division and vice versa for power combining as shown in Figure 1. Power
divider finds applications in coherent power splitting of local oscillator power, antenna feedback
network of phased array radars, external leveling and radio measurements, power combining of
multiple input signals and power combining of high-power amplifiers.
