    Samenvatting

    In recent years, responding to the need of the astronomical community, superconductor-insulator-superconductor (SIS) mixers have been developed to operate at THz frequencies. Best results are obtained by using niobium-based tunnel junctions with well-matched low-loss normal metal striplines, which are found to be less lossy than niobium striplines operated above the gap-frequency of niobium (700 GHz). Niobiumnitride tunnel junctions with a magnesiumoxide tunnel barrier, although having reasonable quality current-voltage characteristics, have been found to be unsuitable due to excess shot noise resulting from pinholes in the barrier.
