Abstract: 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.

Abstract: A mechanical switch for switching microwave signals and the like from one coaxial-type connector to another includes a housing to which are mounted three coaxial-type connectors with their inward ends located adjacent first and second jumpers. The first jumper is supported at one end of a first slider which is movable between a closed position at which two connector ends are electrically connected by the first jumper and an isolated position at which the two connector ends are not electrically connected by the first jumper. The second jumper is supported at one end of a second slider which is movable between a closed position at which two others of the connector ends are electrically connected by the second jumper and an isolated position at which the two other connector ends are not electrically connected together by the second jumper. A spring moves the second slider to its isolated position when the first slider is moved to its closed position and visa versa.
