ABSTRACT:
A system or method for calibrating an RF transmitter includes inputting a test tone to the RF transmitter. LO leakage calibration is performed on an output of the RF transmitter with the test tone inputted thereto, in order to determine a minimum LO leakage. Thereafter, sideband image calibration is performed on the output of the RF transmitter with the test tone inputted thereto, in order to determine a minimum sideband image. Operational values for the RF transmitter are stored in memory based on the detected minimum LO leakage and the detected minimum sideband image, to be used during a normal operation mode of the RF transmitter.
