A novel type of power divider, featuring arbitrary power ratio and arbitrary ripple level, is proposed. This divider consists of a two‐port filtering structure connected to a circulator and is straightforwardly designed using microwave filter synthesis techniques. An example is provided, with low‐pass domain synthesis and experimental divider demonstration at the X‐band, after low‐pass to bandpass transformation. The experimental divider prototype is an iris coupled‐resonator waveguide structure, whose response is found in good agreement with theoretical predictions. © 2013 Wiley Periodicals, Inc.
