Abstract :
This paper is a research on the conversion efficiency of high-temperature superconductivity bicrystal Josephson junction mixer at THz. Using ion etching, junction integrated with antenna is prepared. Experiment on microwave exposure less than 650GHz has been obtained using miniature pulse tube refrigerator system. Conversion efficiency depended on local oscillation power, microwave signal power, harmonic order, bias electric current, etc., has been tested and analyzed.
