Cet article présente un diviseur de puissance Wilkinson (WPD) à éléments localisés utilisant des circuits en échelle LC composés d'un condensateur et d'une inductance, et d'un circuit série LR/CR. Le WPD proposé ne comporte que sept éléments. Grâce à la conception du diviseur basée sur une technique d'analyse en mode pair/impair, nous montrons théoriquement que des WPD à large bande peuvent être réalisés par rapport aux WPD à éléments localisés composés de réseaux Π/T et d'une résistance d'isolement. En concevant le WPD pour qu'il corresponde à deux fréquences de fonctionnement, une bande passante relative d'environ 42 % peut être obtenue. Cette valeur est supérieure à celle du WPD conventionnel basé sur la théorie des circuits distribués. Une simulation et des expériences électromagnétiques sont effectuées pour vérifier la procédure de conception du WPD à éléments localisés conçu à une fréquence centrale de 922.5 MHz, et un bon accord avec les deux est montré.

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.
