Methods and apparatus to pre-compensate for I/Q distortion in quadrature transmitters

Methods and apparatus to pre-compensate for I/Q distortion in quadrature transmitters

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 resis...

description 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.
