A 920MHz Lumped-Element Wilkinson Power Divider Utilizing LC-Ladder Circuits
Summary :
This paper presents a lumped-element Wilkinson power divider (WPD) using LC-ladder circuits composed of a capacitor and an inductor, and a series LR/CR circuit. The proposed WPD has only seven elements. As a result of designing the divider based on an even/odd mode analysis technique, we theoretically show that broadband WPDs can be realized compared to lumped-element WPDs composed of Π/T-networks and an isolation resistor. By designing the WPD to match at two operating frequencies, the relative bandwidth of about 42% can be obtained. This value is larger than that of the conventional WPD based on the distributed circuit theory. Electromagnetic simulation and experiment are performed to verify the design procedure for the lumped-element WPD designed at a center frequency of 922.5MHz, and good agreement with both is shown.

Abstract: This paper presents a lumped-element Wilkinson power divider (WPD) using LC-ladder circuits composed of a capacitor and an inductor, and a series LR/CR circuit. The proposed WPD has only seven elements. As a result of designing the divider based on an even/odd mode analysis technique, we theoretically show that broadband WPDs can be realized compared to lumped-element WPDs composed of Π/T-networks and an isolation resistor. By designing the WPD to match at two operating frequencies, the relative bandwidth of about 42% can be obtained. This value is larger than that of the conventional WPD based on the distributed circuit theory. Electromagnetic simulation and experiment are performed to verify the design procedure for the lumped-element WPD designed at a center frequency of 922.5MHz, and good agreement with both is shown.
