MILLIWAVE/SUB-MILLIWAVE RECEIVER BASED ON INTEGRATED CIRCUIT INCLUDING INTRINSIC JOSEPHSON ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a milliwave/sub-milliwave receiver that has teraheltz-band antennas and choke circuits, can receive teraheltz waves with high sensitivity, and is based on an integrated circuit including an intrinsic Josephson element. SOLUTION: In this milliwave/sub-milliwave receiver based on the integrated circuit including the intrinsic Josephson element, a plurality of intrinsic Josephson junction devices 42 and 43 having many junctions worked on both surfaces are integrated on a substrate 40 containing the antennas and choke circuits. This receiver receives a milliwave/sub-millliwave with high sensitivity by generating a zero-crossing step is generated in its current-voltage characteristic by radiating the milliwave/sub-milliwave from the substrate 40 side.
