Abstract
The method of calibration of a second order intermodulation intercept point (IIP2) of a radio transceiver comprises the steps of: generating a second order intermodulation (IM2) reference signal (STXIM2-REF) from a transmission baseband signal (STXBB-REF); estimating a second order intermodulation power from the second order intermodulation reference signal (STXIM2-REF) and a radio transceiver output signal (Output); tuning a second order intermodulation intercept point tuner to find a lowest second order intermodulation power; extracting an optimum second order intermodulation intercept point corresponding to the lowest second order intermodulation power.
