| Abstract: | The research work on the conversion efficiency of high-temperature superconductivity bicrystal Josephson junction mixer is reported. Using ion etching, the junction integrated with antenna is prepared. Experiment on harmonic mixing at 3 mm waveband is carried out. The relationship between conversion efficiency and the parameters of local oscillation power, microwave signal power, harmonic order, bias electric current, etc., is tested and analyzed. |
