Topology and Design Formulas for Four-Way Filtering Power Divider With Wide Isolation Range

In this paper, we present a topology with design equations for the rigorous of multiway power dividers having pre-defined filtering response featuring broadband isolation between any pair output ports. Hence, divider designed using presented and formulas can suppress undesired oscillations at spurious frequencies when used as combiner. More importantly, provide complete mathematical designing various responses. Therefore, it is possible to without relying on time-consuming parametric sweeps or heuristic approaches. The have been verified by designing, fabricating, measuring four-way second-order divider.
