An active up conversion mixer covering the entire 71-86GHz Eband range in SiGe Technology

Abstract

An IF to RF up-conversion mixer for the entire E-BAND 71-76GHz and 81-86GHz frequency range was designed and fabricated in IBM 0.12μm SiGe technology. The Mixer comprises of a double balanced Gilbert-cell with a degeneration inductor in the amplifying stage for increased linearity. The mixer exhibits conversion gain higher than -2dB, output compression point above -7dBm, and LO leakage less than -30dB. The core mixer area is 0.37mm2 and consumes 140mW from a 2.7V power supply. © 2013 IEEE.
