A thin-film, lumped element filter utilizing spiral inductors and capacitive pi networks is disclosed. The filter is fabricated from a planar dielectric substrate having a ground plane on one side thereof and two thin-film metal layers and an insulation layer disposed therebetween on the opposite side of the dielectric substrate. The metal and insulation layers are configured to form one or more capacitive pi networks and spiral inductors, which are electrically interconnected to form the filter.
