Abstract An ultra-wideband unequal-split Wilkinson power divider with a 2:1 split ratio is presented. To achieve the ultra-wideband characteristics, the conventional quarter-wave arms of the divider are replaced by tapered lines. Moreover, two extra tapered transformers are incorporated at the output ports for matching purposes as the designed divider is of an unequal-split type. To obtain good isolation between the output ports, five isolation resistors are used, the values of which are determined using the simple odd-mode analysis of the Wilkinson power divider. For verification purposes, an ultra-wideband Wilkinson power divider that operates over a frequency range extending from 2 to 12 GHz is designed, simulated, fabricated, and measured. The results of the full-wave simulation and measurements verify the validity of the design procedure.
