This brief presents a novel design of a dual-band equal split Wilkinson power divider. It is based around a single coupled line section as core and uses stub-based port matching networks at each of the ports. It then incorporates only one isolation resistor, which is independent of frequency-ratio, for achieving perfect isolation. Closed form design equations are developed for the general analysis of the power divider and design case studies are provided to evaluate the proposed design. The developed prototypes for frequency-ratios of 2 and 7 show a good agreement between the electromagnetic simulated and measured results and thus validate the reported theory.
