Patent number: 6933748Abstract: A filter network designed for providing high frequency selectivity with a high degree of reliability and availability. The filter network comprises a superconducting filter and a non-superconducting filter, or a combination thereof to form multiplexers. A receive side of the non-superconducting filter pre-filters received RF signals before inputting them to the superconducting filter. The non-superconducting filter is constructed and arranged to pass RF signals having a frequency within a first pass band to the superconducting filter. The superconducting device is constructed and arranged to exhibit a high-degree of frequency selectivity in further narrowing the received RF signals. Other aspects are directed to the arrangement, construction, and uses of the same structures to accomplish different but similar goals.Type: GrantFiled: May 6, 2003Date of Patent: August 23, 2005Assignee: Superconductor Technologies, Inc.Inventor: Gregory L.

Patent number: 6700459Abstract: A dual-mode resonator comprises a dielectric substrate having a region divided into four quadrants, and a ring resonator forming quadrangularly symmetrical configurations within the four quadrants of the region. The symmetrical configurations may be formed from folded sections of the resonator, so that parallel lines with opposite currents that cancel to minimize the far-field radiation of the filter structures. The symmetrical configuration can also be meandered, so that opposite currents in parallel line segments within each meander and the line segments that interconnect the meanders cancel to minimize the far-field radiation of the filter structures. One resonator can be used in a two-pole dual-mode filter structures, or multiple resonators can be used in more complex dual-mode filter structures.Type: GrantFiled: May 29, 2002Date of Patent: March 2, 2004Assignee: Superconductor Technologies, Inc.Inventors: Kurt F.

Patent number: 5856768Abstract: An electrical interconnect provides a path between cryogenic or cryocooled circuitry and ambient temperatures. As a system, a cryocable 10 is combined with a trough-line contact or transition 20. In the preferred embodiment, the cryocable 10 comprises a conductor 11 disposed adjacent an insulator 12 which is in turn disposed adjacent another conductor 13. The components are sized so as to balance heat load through the cryocable 10 with the insertion loss. In the most preferred embodiment, a coaxial cryocable 10 has a center conductor 11 surrounded by a dielectric 12 (e.g. Teflon.TM.) surrounded by an outer conductor 13 which has a thickness between about 6 and 20 microns. The heat load is preferably less than one Watt, and most preferably less than one tenth of a Watt, with an insertion loss less than one decibel. In another aspect of the invention, a trough-line contact or transition 20 is provided in which the center conductor 11 is partially enveloped by dielectric 12 to form a relatively flat portion 28.Type: GrantFiled: April 26, 1996Date of Patent: January 5, 1999Assignee: Superconductor Technologies, Inc.Inventors: Gregory L.
