A 71-86GHz multi-tanh up-conversion mixer achieving +1dBm OP1dB in 0.13 μm SiGe technology
Abstract
A high output 1dB 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 μm 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 1dB compression are 3.9dB and +1dBm, respectively at 71GHz and vary within 3dB and 4dB respectively 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. © 2014 IEEE.
