Abstract:	This paper proposes a novel three-dimensional digital predistorter (3D-DPD) suitable for compensating nonlinear distortion in dual-band (DB) envelope tracking (ET) power amplifiers (PAs). By taking into account the cross-band modulation effects (due to DB operation) and the slow-envelope dependent distortion effects (due to ET), the 3D-DPD is design by properly modifying the memory polynomial (MP) behavioral model. In a first approach, the accuracy and reliability of the proposed 3D-MP model are evaluated. Finally, experimental results are shown to validate the linearization performance of the proposed 3D-DPD.
