An apparatus relates generally to multi-path digital predistortion. In this apparatus, a single-band digital predistorter engine has first and second sample paths. An input stage is coupled to receive input samples and configured to separate them into first samples and second samples. The input stage provides first and second magnitudes for the first and second samples, respectively. A first set of digital predistorters receives the first samples, the first magnitudes and the second magnitudes. A second set of digital predistorters receives the second samples, the second magnitudes and the first magnitudes. An output stage is coupled to receive predistorted outputs from the first set of digital predistorters and the second set of digital predistorters and is configured to provide a digital predistorted composite signal from the first set of digital predistorters and the second set of digital predistorters.
