LOW NOISE MICROWAVE RECEIVER

FABRICATION OF A LOW-NOISE MICROWAVE RECEIVER USING HIGH TEMPERATURE SUPERCONDUCTORS DEPENDS UPON THE ABILITY TO FABRICATE INDIVIDUAL SUPERCONDUCTING MICROWAVE COMPONENTS, DETERMINATION OF THE OPTIMAL USAGE OF SUPERCONDUCTING COMPONENTS IN CONJUNCTION WITH CONVENTIONAL (NON SUPERCONDUCTING) ONES, AND SPECIFICATION OF A RESULTING DESIGN. SEI WILL DESIGN, FABRICATE, AND TEST AN EDGE-COUPLED FILTER AND LANGE COUPLER USING HIGH TEMPERATURE SUPERCONDUCTING THALLIUM-BASED THIN FILMS, AND WILL DETERMINE THE FEASIBILITY AND APPROPRIATENESS OF USING HTS THIN FILMS FOR MIXER CIRCUITS. COMPLETION OF THESE ACTIVITIES WILL LAY THE GROUNDWORK OF COMPONENT DEVELOPMENT REQUIRED TO ASSEMBLE AND TEST A SIMPLE FUNCTIONAL LOW NOISE RECEIVER.
