Abstract : A broadband Gysel divider has been demonstrated. The new concept uses a coupled line segment in the design to improve isolation and matching. Significant improvement in operation bandwidth are realized compared to the conventional approach, while maintaining low-loss, ease of design, and flexibility. The coupled-Gysel divider is demonstrated with a 2.5 8GHz, 105% fractional bandwidth, and 0.1 dB loss. Another divider operates from 3.4 10.2 GHz, with 100%fractional bandwidth and 0.2 dB of insertion loss. The structure works well reciprocally as a combiner. A novel isolation structure will also be presented.
