OP1dB in 0.13 f.lm SiGe Technology

A high output IdB compression up-conversion mixer for the entire E band frequency range, 71-76 GHz and 81- 86 GHz, is designed and fabricated in IBM 0.13 IJm SiGe technology. The mixer is comprised of a double balanced Gilbert cell and a multi-tanh three transistor hybrid transconductance stage, used to enhance the mixer linearity. The conversion gain and output IdB compression are 3.9dB and +ldBm, respectively at 71GHz and vary within 3dB and 4dB res pectively over the entire 15GHz range. LO leakage is less then -30dB and noise figure is under 9dB. The circuit consumes 80mW from a 2.7V supply.
