Wilkinson Power Divider Theory



Wilkinson power divider is a solution of the loss less T-junction problems, which are not matched and non-isolated output ports. The resistive T-junction divider can be a solution for the matching problem but the isolation part cannot be solved and also this solution leads a power loss because of the resistive structure of the resistive T-junction divider. Wilkinson power divider is a lossy three port network and it has a property of being lossless when the output ports are matched. In addition, the isolation between output ports are can be achieved in Wilkinson power divider. Dissipated power in the Wilkinson power divider is from the reflected power. There are two general type of the Wilkinson power dividers; first one is the equal power divider and the second one is unequal power divider.
