Abstract : Mixing experiments on niobium point contacts are reported for conversion from 95 GHz to 140 MHz. The conversion efficiency is less than predicted by the highly damped weak link model. The discrepancy is presumably due to mixing with higher harmonics of the local oscillator. The lowest noise temperature measured was T approximately equal to 100K which is of the same order as recently reported for cooled Schottky-barrier diodes. (Author)
