Abstract :
It is experimentally shown that an Nb-Nb point contact Josephson junction can be used as a very sensitive spectrometer of good frequency resolution in the range of millimetre waves by applying an inverse Hilbert transform on a characteristic deformation of its I/V characteristic caused by the absorbed RF energy.
