Abstract

Abstract A multichip module (MCM) is formed with external connections on coaxial pins. This provides an impedance between a ground connection and a signal connection which is substantially equal per unit length. The module may be configured so that the impedances of the connections between the signal connections and integrated circuit may also be optimally impedance matched.
