Wilkinson Power Divider Simulation
A Wilkinson power divider is a common three-port power splitter circuit that is used to split an input signal into two equal output signals, or to combine two signals into one. Unlike resistive or T-junction power dividers, a Wilkinson power divider allows for nearly complete isolation between the two ports and adds no resistive losses to the power split. Because of these characteristics, a Wilkinson divider is widely used in radio communication systems due to its ability to prevent crosstalk between channels — a phenomenon where one signal (or channel) affects the transmission of another signal (or channel). Here, we’ll look at how a Wilkinson divider can be simulated using COMSOL Multiphysics and the RF Module.
