Compact, Harmonic Suppressed Gysel Power Divider with Plain Structure

A novel compact Gysel power divider with up to 12th, harmonics suppression was proposed in this study. Incorporation of six similar low-pass filters into the conventional Gysel power divider is applied to this design. The proposed power divider reduces the occupied area to only 9 % of the conventional Gysel power divider at 625 MHz (91 % size reduction). A comprehensive comparison between the proposed design and other published studies substantiates the superiority of the proposed design in terms of circuit size and stop-band bandwidth. Furthermore, this design retains the high-power handling capability over the Wilkinson power divider.
