摘要

We report on the high frequency properties of high-Tc superconductor (UTS) Joac.phson junctions using mixing experiments in the frequency range 18 GHz-119 GHz. Experiments with YBa^CusOj (YBCO) step-edge (SEJ) ild hicryatal junctions on LuAlO-j and MgO substrates have been performed, fin order lo achieve, optimal junction properties we performed an oxygen sma treatment. Junctions with RSJ-like current .voltage characteristics e mounted into a heterodyne mixing setup. We obtat7ied conversion effi-|%tnes around -J,0 dB and heterodyne mixing response, above 1 THz. For SEJh we observed mixing response related to a second junction in series. We bko investigated selj'-mixing properties.
