Abstract
A resistor-capacitor network for terminating transmission lines. The network includes a core of dielectric material. Capacitors are formed within the core from spaced apart electrode plates. Terminals extend from the electrode plates to a top surface of the core. The electrode plates are oriented perpendicular to the top surface. Ball pads are located on the top surface. Resistors are located on the top surface and are connected between the ball pads and terminals. Conductive spheres are attached to the ball pads.
