Apparatus and method to introduce signals into a shielded RF circuit

摘要

An interface to a microcircuit formed on a substrate supporting a ground plane. The substrate supports a dielectric structure having gold coated sloped sidewalls electrically connected to the ground plane. A transmission line, connected to the microcircuit, is supported by the dielectric structure. A coaxial cable is connected to the transmission line. The coaxial cable having an end stripped at an angle substantially the same as the sloped side walls of the dielectric structure, wherein the exposed length of the center conductor is bonded to the transmission line, and the outer conductor of the coax cable is bonded to the gold plating on the dielectric structure such that the angled portion of the coax cable mates with the bevel of the thick film dielectric.
