| Zusammenfassung | We present a study of the microwave characteristics of Jospehson junctions based on a superconductor-insulator-normal-insulator-superdoncuctor sandwich, fabricated in NA/Al/AlOx technology. With the nonhysteretic Shapiro steps and the small parameter spread observed, the junctions are suitable for programmable Josephson voltage standards. Their characteristic voltage Vc ≊100 µV enables operation at microwave frequencies up to 100 GHz. |
