A coupled-Gysel broadband combiner/divider is proposed and demonstrated. The new concept relies on using a single coupled line segment in the design. Significant improvement in bandwidth are realized while maintaining low-loss, ease of design, and flexibility. The coupled-Gysel is demonstrated with a 2.5 – 8 GHz (105% fractional bandwidth) divider with 0.1 dB divider loss, and a 3.4 – 10.2 GHz (100% fractional bandwidth) with 0.2 dB divider loss.
