Abstract :
A new balanced-to-balanced Gysel power divider (PD) is proposed for high-power applications, based on a half-mode substrate integrated waveguide (SIW) ring. The ring has a circumference of 2.5 λg, and one port is used for good isolation. The balanced-to-balanced component is easily designed by converting its single-ended counterpart. With the equivalent impedance defined by voltage and current of half-mode SIW, the initial geometry is quickly obtained. Good performance is achieved with our proposed PD, which has been demonstrated by its simulated and measured mixed-mode S-parameters.
