Abstract:
The subject matter discloses an apparatus residing within an RF chip, comprising: a detection unit for detecting IQ mismatch in an IQ signal; an analog calibration module comprising a first analog calibration mechanism for calibrating IQ mismatch in the phase component and a second analog calibration mechanism for calibrating IQ mismatch in the amplitude component; and a control unit for determining a calibration sequence of the IQ signal.
