In radio frequency (RF) power amplifiers (PA), power efficiency, linearity and cost are contradictory requirements. In the Long Term Evolution (LTE) and LTE-Advanced (LTE-A) standards by the Third Generation Partnership Project, maximum power reduction (MPR) is used to relax RF PA requirements in user equipment. In this paper, we analyze the gating factors that determine the MPR in multicluster transmission, a new feature in LTE-A that significantly changes the way unwanted emissions are distributed in the spectrum. The analysis can help in devising more advanced MPR formulas and in development of RF PA linearizers.
