Abstract

An attenuator includes a substrate having first and second surfaces and a plurality of discrete circuit elements. The first surface includes a first electrically conductive pattern providing circuit contacts providing electrical connections among the discrete circuit elements and circuit contacts providing electrical connections to components external to the attenuator. The second surface includes a second electrically conductive pattern.

Claims (27)
