In this paper, a reduced size dual-frequency Wilkinson power divider (WPD) is presented. The miniaturization is accomplished by using two sections of non-uniform transmission line transformers in place of the two uniform sections in the conventional dual-frequency WPD. Two isolation resistors are also used to achieve good isolation between the output ports. Optimization is carried out based on simple uniform transmission line theory. For veriflcation purposes, a dual-frequency WPD operating at 0.5GHz and 1GHz is designed, analyzed and fabricated.
