A design method of dual-frequency wilkinson power divider

This paper treats a novel Wilkinson power divider operating at two arbitrary different frequencies. The proposed divider consists of two-section transmission lines and a series RLC circuit connected between two output ports. The circuit parameters for a dual-frequency operation are derived by the even/odd mode analysis. Equal power split, complete matching, and good isolation between two output ports are demonstrated. Finally, verification of this design concept is shown by using an electromagnetic simulator.
