Patent number: 11367983Abstract: A connection system for a quantum computer that employs constant impedance connectors with attenuation or filtering components or both embedded therein or within an adaptor removably insertable within an adaptor housing for use in a cryogenically cooled quantum computer. The connection system provides a higher density of cables traversing through a hermetic sealed top plate, and which are accessible to chill blocks to reduce the thermal energy from the signal lines. Attenuators or filter circuits are embedded in the constant impedance connector housings, or provided in adaptors that connect on each end to form mating constant impedance connections, in order to reduce signal strength as the signal progresses through the cryogenic environment and to remove extraneous electrical signal noise.Type: GrantFiled: December 3, 2020Date of Patent: June 21, 2022Assignee: The Phoenix Company of Chicago, Inc.Inventors: John E. Maturo, Robert M. Bradley

Patent number: 9559480Abstract: A method, system and apparatus for making an interconnection between power cables and signal cables. A single electrical interface in mid- or backplane applications is introduced to accommodate a wide range of board thickness variations while maintaining a desired interface relationship, using a connector plug bushing, a male connector having a sliding fit with the bushing, a first coaxial connector plug, a female connector plug with a housing width sized to provide a sliding fit within the connector plug bushing inner opening, and a second coaxial connector plug in the free end of the female connector plug for connection to the power and signal cables. A constant impedance connector is used with the interconnection of the RF signal and power cables.Type: GrantFiled: January 29, 2016Date of Patent: January 31, 2017Assignee: The Phoenix Company of Chicago, Inc.Inventors: Robert M.

Patent number: 7056128Abstract: The present invention is directed to a high density electrical connector which can provide 80 or more twinax connections per linear inch in a 20 millimeter card slot. In a typical electronic system package, 20 millimeters is the spacing from center line to center line of the adjacent parallel daughtercards. Twinax cable is coaxial cable that contains two .inner conducting wires rather than one. The two inner conducting wires provide two physical channels. Coaxial cable is called “coaxial” because it includes one physical channel that carries the signal surrounded (after a layer of insulation) by another concentric physical channel, both running along the same axis. The outer channel serves as ground.Type: GrantFiled: October 25, 2004Date of Patent: June 6, 2006Assignee: Litton Systems, Inc.Inventors: Michael P. Driscoll, Stephen Vetter, Robert M. Bradley

Patent number: 6910897Abstract: An interconnection system includes spacers arranged adjacent each other in a row, the spacers having cable sections disposed therein. Each cable section has at least one center conductor and an outer conductive shield. All of the cable sections have one end exposed on a first plane and a second end exposed on a second plane. Electrically conductive contacts are disposed within apertures in a pair of interposers so as to have one end making electrical contact with one of the cable sections and another end extending through its respective aperture in its respective interposer.Type: GrantFiled: September 5, 2002Date of Patent: June 28, 2005Assignee: Litton Systems, Inc.Inventors: Michael P.
