Briefly, a method and apparatus to compensate an imbalance of a modulator by providing calibration parameters to a calibration network. The modulator may receive a pair of predetermined sinusoidal in-phase and quadrature signals and output a distorted modulated signal. A processor may process spectral parameters at first and second harmonics of a detected envelope signal of the distorted modulated signal may generate the calibration parameters.
