Dual-frequency power divider with isolation stubs

A novel dual-frequency power divider with isolation stubs is presented. To reduce the parasitic effects between the two stubs that are connected by the isolation resistor in traditional Wilkinson power dividers, a structure consisting of isolation stubs is proposed. The corresponding design equations are obtained to calculate the design parameters of the desired dual-frequency power divider. Finally, this design concept is validated by experimental results on a 0.95/2.09 GHz dual-frequency power divider.
