Exploring architectural differences between sub-6GHz and mmWave base station radios, with particular emphasis on the challenges and benefits of implementing Digital Pre-Distortion (DPD) on these systems. Using a 256 element mmWave array, with beamformers and transceivers, demonstrating how DPD improves the EIRP (Effective Isotropic Radiated Power) by up to 3dB. Thus allowing for 30% reduction in the number of array elements, relative to an array without DPD, for the same target EIRP.
