Abstract :
An eighth order subharmonically pumped mixer for the implementation of a millimetre wave imaging system is presented. The block receives the RF signal in the WR-3 band, between 220 and 330 GHz, and downconverts it to a 300 MHz intermediate frequency, using the internally generated eighth harmonic component of an input signal in the WR-28 frequency band, between 26.5 and 40 GHz. The subharmonic mixing operation is performed taking advantage of the non-linearity of a few layer graphene component, integrated in a microstrip structure.
