Harmonic Mixing with SIS Tunnel Junctions in the Millimeter and Submillimeter Regions
Abstract
The characteristics of SIS (Superconductor-Insulator-Superconductor) harmonic mixing were studied in the millimeter and submillimeter regions. IF (Intermediate Frequency) signals originating from the Josephson effect and the photon-assisted tunneling were observed. Each property was investigated by applying a magnetic field. Compared with mixing based on photon-assisted tunneling, mixing by the Josephson effect required low LO (Local Oscillator) power and gave rise to a smaller conversion loss, but more noise.
