| Abstract(in English) | Josephson self-pumping mixing experiment was studied with YBCO step-edge Josephson junctions. To eliminate the hysteresis on the current-voltage characteristics, the junction was shunted with Au thin film, and we obtained the RSJ-like characteristics without hysteresis. The junction was integrated with an Au thin-film log-periodic antenna, and irradiated a signal quasi-optically. The 300 GHz oscillator was used as a signal source, and we obtained the IF output as a beat signal of the signal and the Josephson self-oscillation. By the measurement of the Y-factor method, we obtained the noise temperature of 2,000 K (DSB) as the YBCO self-pumping mixer. |
