Abstract :
An IF to RF up-conversion mixer for the entire E-BAND 71-76 GHz and 81-86 GHz frequency range was designed and fabricated in IBM 0.12 μm 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 -2 dB, output compression point above -7 dBm, and LO leakage less than -30 dB. The core mixer area is 0.37 mm2 and consumes 140 mW from a 2.7 V power supply.
