"NettetThe power efficiency and the linearity of a power amplifier (PA) depend on its operating point. A high efficiency generally corresponds to poor linearity. To optimize the efficiency/linearity tradeoff, crest factor reduction (CFR) techniques are classically implemented along with digital predistortion (DPD) to control the PA operating point. … " - Linearization approaches for amplifiers
