Abstract :
In this work, a millimetre wave receiver prototype integrating a graphene based subharmonic mixer and a diagonal horn antenna is presented. The block receives a millimetre wave signal in the WR-5 frequency band (140-220 GHz), which is downconverted using a high-order harmonic component of the local oscillator signal, in the WR-28 frequency band (26.5-40 GHz), producing an IF output at 300 MHz. A prototype has been manufactured using high precision 3D printing techniques. The performance for subharmonic orders 6, 8 and 10 has been evaluated through preliminary measurements in the neighbouring WR-3 frequency band. Measured radiation patterns are also presented.
