  • Abstract
    A highly-linear 400MHz-3GHz RF front-end is presented. At full gain of 16dB, the 2V LNA and passive mixer boosts 1dB out-of-band blocker compression up to +2dBm, and obtains an untuned, uncalibrated out-of-band IIP3 of +18dBm and IIP2 of +61dBm. A NF of less than 3dB is achieved for just 6.5mA front-end current consumption (excluding LO generation) at an area of 0.08mm2 in 90nm digital CMOS. This front-end therefore paves the way to relaxing the antenna filter requirements.
