Abstract: A method for calibrating a radio frequency (RF) transmitter to compensate for a frequency-dependent in-phase quadrature (FDIQ) mismatch is disclosed. The method may include determining in-phase quadrature (IQ) amplitude and phase mismatches of the RF transmitter for a lower side band (LSB) and an upper side band (USB), determining a FDIQ mismatch based on linear fitting the IQ amplitude and phase mismatches for the LSB and the USB, modifying the FDIQ mismatch based on flipping a FDIQ phase mismatch in the LSB and flipping a FDIQ phase mismatch in the USB to generate a modified FDIQ mismatch, determining Fourier coefficients based on applying an inverse fast Fourier transform to the modified FDIQ mismatch, and determining FIR coefficients for a finite impulse response (FIR) filter of the RF transmitter based on windowing the Fourier coefficients.
