Abstract : An attenuator and termination having a relatively flat frequency response for attenuating and dissipating electrical energy is comprised of a plurality of cascaded tee attenuator sections formed on a substantially flat surface ceramic substrate comprised of alumina, for example. The attenuator sections are configured from a single thin film series resistor comprised of gold and a plurality of shunt resistors formed from a layer of cermet which underlies the gold film resistor. The cermet shunt resistors extend away from the series resistor to the side edge of the substrate where they terminate in a ground contact configuration which wraps around the side and lower surface of the substrate.
