Design of Wilkinson Power Divider

By analyzing the traditional wilkinson power divider and quarter impedance transformer, a new ultra-wideband power divider is proposed and designed. The measure result agree with the simulation result of ADS and Ansoft HFSS. In 500MHz to 2.2GHz frequency, the port return loss is less than -18dB, in 460MHz to 2.7GHz frequency, the port return loss is less than -15dB, the isolation is more than 12dB.
