Millimeter-wave detection under the heterodyne mixing mode has been carried out on high-Tc superconducting GBJJ (Grain Boundary Josephson Junction). GBJJ was fabricated from high-Tc superconducting Y-Ba-Cu-O films were prepared on YSZ and SrTiO/sub 3/ substrates using an RF sputtering technique. Patterning of the junction has been successfully made by chemical wet-etching method with phosphoric acid solution. The authors carried out experiments in the heterodyne mixing made for a signal of 35 GHz with local oscillation at 34.97 GHz. The detected IF output power was obtained at the bias voltage lying midway between the zeroth and first Shapiro steps. They have obtained the mixer conversion efficiency of - 15 dB with a dynamic range of about 20 dB at 35 GHz. This result strongly implies that high-Tc superconducting GBJJ well worked as a detector at millimeter-wave frequencies.
