  • Patent number: 5285018
    Abstract: A controlled impedance power and distribution network wherein -x- and -y- direction planes of interpositioned power and signal conductors with a dielectric layer between planes and separating each plane from a ground plane are assembled. The network provides the ability to distribute many power levels with all power and signal conductors electrically referenced to ground along their length and each signal conductor also electrically referenced to its respective power level along its length. The network is of particular advantage in the TFM technology in distributing multiple power levels with fewer layers.
