This paper shows a very compact Wilkinson power splitter for high integrated millimeter wave systems. The approach, to reduce the component's size, is based on the lumped component transformation for the lines. The simulation on the splitter structure shows a very wide band with 0.5 dB of maximum insertion loss and only 0.07 dB of maximum output amplitude imbalance. The input return loss is better than -21 dB within the whole band of interest (57 - 67 GHz) the output return loss is better than -21.5 dB for the same band. The isolation between the two outputs is betterthan -20 dB. The occupied area for the entire structure is around 0.0055mm2
