description An apparatus includes a first circuit to receive a first input data, a second input data and coefficients, generate a first distortion term and a second distortion term based, respectively on the first input data and the coefficients and the second input data and the coefficients, and change a polarity of the first distortion term and the second distortion term. A first subtraction circuit subtracts the first distortion term from the first input data and generates first difference data, and a second subtraction circuit subtracts the second distortion term from the second input data and generates second difference data. A transmit data-path generates a RF output. The first difference data and the second difference data compensate, based on the polarity changes of the first distortion term and the second distortion term, respectively, one or more impairments of the RF output.
