  • Methods and apparatus to pre-compensate for I/Q distortion in quadrature transmitters
    Patent number: 7848450
    Abstract: Methods and apparatus to pre-compensate for in-phase/quadrature (I/Q) distortion in quadrature transmitters are disclosed. A disclosed example method comprises coupling a portion of an analog baseband in-phase signal to an analog baseband quadrature signal through an impedance, and selecting a resistance value for the impedance to pre-distort the analog baseband quadrature signal to compensate for an error introduced by modulation of the analog baseband in-phase signal and the analog baseband quadrature signal.
    Type: Grant
