摘要： Systems and methods for an upgradeable and/or reconfigurable receiver are provided. In general, the present invention is directed to providing systems and methods for designing an electronic communication system having easy and cost effective upgradeable receiver systems and components including, for example, an amplifier and/or a filter. For example, a receiver may include a receiver front end that is configured so that at least one of the original conventional system components may be used along with one or more new system components to provide greater receiver sensitivity and/or selectivity. In various embodiments, portions of an upgradeable receiver system may be made as modular components that allow easy replacement for the upgradeable components which may include a signal amplifier and/or a signal filter. In various embodiments the receiver may be upgraded by replacing a conventional low noise amplifier (LNA) with a high temperature superconductor (HTS) filter and/or a cryo-cooled LNA.

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： An a-axis high temperature superconducting film having preferential in-plane orientation is formed. In the preferred embodiment, an a-axis film has substantial amounts of superconductor oriented with its c-axis in a unified direction. YBCO on neodymium gallate (110) plane has resulted in a high temperature superconductor with over 80% by volume being a-axis with c-axis in-plane alignment in one preferential direction. These films are epitaxial. The preferred method of film growth is for in situ growth by laser ablation. Preferably, the a-axis film is nucleated by laser ablation on onto a substrate which is at a temperature of 50 to 100.degree. C. less than the optimal substrate temperature for c-axis growth. Optionally, once a-axis nucleation has begun, the substrate temperature may be increased to optimize superconductor properties.

摘要： The methods and apparatus disclosed enable controlled growth of multicomponent metal oxide thin films, including high temperature superconducting (HTS) thin films, which are uniform and reproducible. The method and apparatus enable a controlled flow and pressure of a gaseous phase of metal containing molecules to be introduced into a reaction chamber, or into an analysis chamber, or into both. The flow into the reaction chamber enables deposition of metal oxides on a substrate and, therefore, growth of multicomponent metal oxide thin films, including HTS thin films, on the substrate. The flow into the analysis chamber enables compositional analysis of the gas. The apparatus also allows adjustment of the gaseous phase flow and pressure into the reaction chamber based upon the results of the compositional analysis. In one aspect of this invention, a heating mantle provides substantially uniform heating throughout the apparatus.

摘要： Lumped element electrical components, such as inductors and capacitors, are formed to include high temperature superconducting materials. In the preferred embodiment, thin film epitaxial high temperature superconductors are patterned to form capacitors and inductors on low loss substrates. Preferably, a ground plane is formed on the back side of the substrate, most preferably being formed of high temperature superconducting material, or other highly conductive materials such as gold or copper. Various advantageous structures include a planar spiral structure, a zig-zag serpentine structure, a single coil structure and a double coil structure. Single layer and multilayer structures are included. Improved narrow bandpass filters, bandreject filters and high Q resonator structures are formed. Chebyshev bandpass filters are formed from multiple series connected zig-zag filter structures. Chebyshev, elliptic and quasi-elliptic bandreject filters are formed from a plurality of bandreject structures, each of which includes a zig-zag or serpentine inductor. A quasi-elliptic bandpass filter utilizes a plurality of series connected bandpass structures with planar cross-coupling of bandpass structures.

摘要： Active superconductive devices are formed having a variable conductive element in electromagnetic contact with a superconductor. In one embodiment, a variable ohmic conductive device, such as a photoconductor, is placed adjacent a superconductor. By varying the optical radiation on the photoconductor, the electromagnetic environment adjacent the superconductor is changed, resulting in changed electrical properties. The superconductor may be patterned as a reject filter, with a photoconductor forming a microwave switch. Alternatively, a delay line plus variable ohmic element forms a phase shifter.
