A Novel Impedance-Transforming Coupled-Line Power Divider Combining Wilkinson and Gysel Structures

摘要

A brand new coupled-line power divider combining the Wilkinson and Gysel structures is proposed in this work. This new design possesses the advantages of both wideband and high-power handling ability of Wilkinson and Gysel power dividers simultaneously. By using the coupled transmission lines and eliminating the 180-degree transmission lines in conventional Gysel structures, the area consumption of the proposed new design is dramatically reduced. Moreover, the proposed circuit is capable of input-to-output impedance transformation.
