A novel coupled-line structure is proposed to design dual-band and high-power Gysel power dividers. Based on traditional even-and odd-mode technique, the analytical design theory is given and the electrical parameters analysis is provided. Four numerical examples are presented to demonstrate the flexible dual-band applications. A practical power divider operating at 1GHz and 2 GHz is designed. The calculated and full-wave simulated results verify our proposed idea.

A novel coupled-line structure is proposed to design dual-band and high-power Gysel power dividers with inherent impedance-transforming functions. Based on traditional even- and odd-mode technique, the analytical design methods in closed-form formula are obtained and the accurate electrical parameters analysis is presented. Due to the usage of coupled-line sections, more design-parameter freedom and a wider frequency-ratio operation range for this kind of dual-band Gysel powder divider are obtained. Several numerical examples are designed and calculated to demonstrate flexible dual-band applications with different impedance-transforming functions. A practical microstrip power divider operating at 2 GHz and 3.2 GHz is designed, fabricated, and measured. The good agreement between the calculated and measured results verifies our proposed circuit structure and analytical design approach.
