Compact, Harmonic Suppressed Gysel Power Divider with Plain Structure

Abstract

AbstractA 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.
