  • Abstract
    A SiGe 8-12 GHz image reject mixer with tunable performance is presented. Control voltages and currents allow the mixer performance to be “healed”, nullifying effects of process variation or environmental changes. Conversion gain greater than 10 dB and output P1dB greater than 0 dBm were obtained in measurement. An image rejection ratio (IRR) of greater than 40 dB was obtained after tuning, a 25 dB improvement over pre-tuned results. The mixer was fabricated in a 150 GHz peak fT SiGe BiCMOS process and consumes 200 mA of current operating on a 4 V rail.
