Systems and methods for providing digital predistortion to compensate for a non-linearity of a power amplifier in a dual-band transmitter are disclosed. In one embodiment, a first baseband signal is tuned to a first intermediate frequency to provide a first intermediate frequency signal. Likewise, a second baseband signal is tuned to a second intermediate frequency to provide a second intermediate frequency signal. The first and second intermediate frequency signals are combined to provide a combined intermediate frequency signal. The combined intermediate frequency signal is then predistorted to compensate for the non-linearity of the power amplifier in the transmitter to thereby provide a predistorted signal. In one embodiment, a separation between the first and second intermediate frequencies and/or a sampling rate for predistortion is minimized based on a target intermodulation order for the predistortion.
