Summary: 
This paper describes a three-port power divider with compensation networks for non-ideal isolation resistor. The compensation networks consist of two pairs of transmission lines and cancel out the parasitic reactance of the non-ideal isolation resistor. The design equations to provide perfect return loss and isolation at a center frequency are presented. The availability of the proposed power divider has been verified by the comparison between calculated and experimental results in the Ku-band.
