Abstract

A radio frequency (RF) front end design is provided with non-linear power amplifiers. The power amplifier operating point and crest factor reduction (CFR) thresholds are adaptively changed to reduce power consumption. A first technique involves adaptively changing peak-to-average power ratio (PAPR) via CFR (dynamic thresholds) to reduce power consumption. A second technique involves adaptively changing the operating point of non-linear power amplifiers depending on the link.
