This letter presents the construction and design equations of a lumped element Wilkinson divider with dual-band operation. This divider is constructed of series and parallel LC resonant circuits, and an isolation resistor. The element values can be uniquely determined by giving the two frequencies for operation as a Wilkinson divider and the load resistance. An 800MHz/2GHz dual-band Wilkinson divider is treated as a design example, and its operation is verified by simulation and experiment. The fabricated divider has compact dimensions of 3.56 × 4mm2.
