Abstract
Systematic IM2 calibration for a differential LNA is disclosed. In an aspect, an apparatus includes an amplifier configured to output an amplified signal having a level of systematic pre-mixer IM2 distortion, a detector configured to detect the level of the systematic pre-mixer IM2 distortion in the amplified signal, and a bias signal generator configured to generate at least one bias signal configured to adjust the amplifier to reduce the level of the systematic pre-mixer IM2 distortion.
