摘要： A HTS-based RF receiver includes a cryocooler and a cryogenic enclosure in thermal communication with the cryocooler. The cryogenic enclosure contains a HTS filter and a LNA therein. A first MEMS bypass switch is positioned between a RF input and the HTS filter, the first MEMS bypass switch operatively coupling the RF input to the HTS filter. A second MEMS bypass switch is positioned between the LNA and RF output, the second MEMS bypass switch operatively coupling the LNA to the RF output. A bypass pathway located within the cryogenic enclosure is connected between the first and second MEMS switches to bypass the HTS filter and LNA when an operating parameter of the RF receiver falls outside a pre-determined range.

摘要： An improved dewar design that accelerates the manufacturing process of a dewar. In a preferred embodiment, the dewar includes an evacuation port that may be larger in size by a factor of ten over the size of evacuation ports of conventional dewars. The oversized evacuation port, however, does not result in an increase in the overall size or profile of the dewar. The dewar is evacuated and hermetically sealed using an re-usable evacuation tool.

摘要： Novel structures and methods for forming useful high temperature superconducting devices, most particularly resonators, are provided. Structures resulting in reduced peak current densities relative to known structures achieve numerous desirable benefits, especially including the reduced intermodulation effects of earlier resonators. In one aspect of this invention, a spiral in, spiral out resonator is provided, characterized in that it has an odd number of long runs, at least equal to five long runs, where the long runs are connected by turns, and wherein there are at least two sequential turns of the same handedness, followed by at least two turns of the opposite handedness. In yet another aspect of this invention, it has been discovered that reducing the size of the input and output pads of HTS resonators increases the relative inductance compared to the capacitance. Yet another resonator structure is a spiral snake resonator having a terminal end disposed within the resonator. A wide in the middle structure and wide at peak current density resonator structures utilize enlarged width portions of the resonator in those areas where current density is largest. In yet another aspect of this invention, operation of resonators in high modes, above the fumdamental mode, reduce peak current densities. Resonators operated in modes in which current in adjacent long runs are in the same direction further serve to reduce current densities, and intermodulation effects. Symmetric current structures and modes of operation are particularly advantageous where far field effects are compensated for.

摘要： Multi-stage electric filters with improved intermodulation-distortion characteristics and a method for designing such electric filters is provided. In general, the invention may include a multi-resonator electric filter in which one or more of the resonators have been intentionally designed to have a different IP and/or Q than the other resonators in the electric filter. In one case, the electric filters include a 4-resonator Chebyshev narrow pass-band filter with at least the first resonator having a Q and/or IP different from at least one other resonator in the filter. The filter thereby has improved IMD power over conventional designed filters while maintaining high Q. In a preferred embodiment the filter may include a superconducting material. The relative Q and IP of the respective resonators in the improved filter may depend on the relative strength of in-band and out-of-band signals. The performance and cost of the electric filter may be optimized by designing the filter to have a relative Q and IP required by the particular application.

摘要： A coated conductor comprises a substrate supporting a ReBCO superconductor adapted to carry current in a superconducting state. The superconductor is characterized in having peaks in critical current (Jc) of at least 0.2 MA/cm2 in a magnetic field of about 1 Tesla when the field is applied normal to the surface of the superconductor and when the field is applied parallel to the surface of the superconductor, and further characterized in that the superconductor includes horizontal defects and columnar defects in a size and an amount sufficient to result in the said critical current response. The conductor is characterized in that the ratio of the height of the peaks in the Jc is in the range from 3:1 with the ratio of the field perpendicular (0 degrees) to the field parallel (+/−90 degrees) to the range from 3:1 with the ratio of the field parallel to the field perpendicular.

摘要： 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. In a multiplexed configuration, various combinations of transmit filters are used to enable the use of a common antenna with the receive side electronics, which may be located at the top of the antenna tower or in the base station.
