Abstract

We propose a new methodology for the design of a dual-band unequal-split Wilkinson power divider (WPD) with a high power division ratio at the operating frequencies. Impractical high-impedance transmission line in the conventional divider is replaced with cascaded dual-band T-section structures based on analytical equations derived herein. To validate the design concept, a dual-band WPD operating at 1 and 2 GHz with a 1:10 split ratio is simulated and measured. Simulations and measurements show isolation and input-output ports matching better than -20 dB, and transmission parameters, S21 and S31 , of -10.5 ± 0.5 dB and -0.4 ± 0.5 dB at the design bands, respectively.
