Abstract

This paper presents a new design of a compact Gysel power divider with harmonic suppression. It comprises six similar low-pass filters in lieu of six conventional transmission lines in the Gysel power divider. Not only does the proposed power divider extremely reduce the occupied area to 22.7% of the conventional Gysel power divider at 900 MHz, but also it features the higher order harmonic rejection. Simulation and measurement results show good insertion loss, return loss, isolation, and wide stopband bandwidth, while maintaining high-power handling capability over the Wilkinson power divider.
