The power amplifier non-linearity and In-Phase/Quadrature (I/Q) imbalance of a transmitter is important RF communication impairment. This paper proves that the distortion of power amplifier output signal in the transmitter includes the non-negligible PM-AM and PM-PM distortion exists in transmitter impairment. Moreover, this paper presents a novel low-complexity dual-band Cartesian Memory Polynomial for modeling and compensating for a concurrent dual-band transmitter. The experimental results verify the high performance of the proposed model in suppressing the adjacent channel error power with low complexity.
