Abstract :
A 100-120 GHz 4× sub-harmonically pumped diode mixer using standard 0.15-μm PHEMT process on 4-mil GaAs substrate is presented. Fourth order mixing was performed using an anti-parallel diode pair. Filters and harmonic stubs are implemented using grounded coplanar waveguide structure. The average conversion loss is 27 dB from 100 to 120 GHz, in a compact chip size of 1.0 × 1.0 mm2.
