Abstract :
This paper describes a sub-harmonically pumped single chip resistive mixer consisting of two pHEMTs, a LO Marchand balun and RF/IF filters. The balun achieves 0.2 dB and 5° of amplitude and phase balance from 17 to 34 GHz. This provides the mixer with over 30 dB of LO rejection and a minimum conversion loss of 9.5 dB over a 34 to 40 GHz RF bandwidth with only 5 dBm of LO power
