Modified Gysel Power Divider for Dual-Band Applications

摘要

This letter presents a modified Gysel power divider for dual-band applications. A short-stub and an open-stub has been attached to the conventional Gysel structure. Closed-form design equations are derived. Power operation analysis shows that the new dual-band circuit maintains Gysel divider's high power handling advantage over Wilkinson divider. The measured results show that good matching, isolation and power transmission can be achieved at two operating frequency bands.
