Splitters and Couplers
Use the splitter and coupler objects and functions to create and visualize splitters and couplers used on a printed circuit board (PCB).
Wilkinson power splitters are commonly used as power dividers for lossless power division and matching between ports. An unequal Wilkinson splitter is used in FMCW radars to split power unequally between the transmitter and the local oscillator or to feed power to beam forming antenna arrays.
Couplers have the unique capability to divide power between two ports with a phase shift. A rat-race coupler splits power as the sum or the difference of the input powers between the output ports. A branchline coupler divides the input power between the output ports with a phase difference of 90 degrees.
