This article reports a wide-band power divider with ultra-wide harmonic suppression. The filtering power divider consists of a Wilkinson power divider and a filter merged into a single structure. For filtering purposes, a novel suppressor cell is designed using resonators of various shapes. The power divider exhibits an operational frequency of 1.64 GHz, encompassing a fractional bandwidth (FBW) of 57 percent, ranging from 1.151 GHz to 2.08 GHz. Notably, it effectively suppresses a total of 24 harmonics, attaining a rejection level exceeding -15 dB. The measured in-band isolation, input return loss, insertion loss, and output return loss are determined at 1.64 GHz to be -23 dB, -36 dB, -3.03 dB, and -18 dB, respectively. These results showcase the superior performance of the proposed design compared to existing state-of-the-art solutions.
