“…This implies that PA's must be designed for high Peak to Average Power Ratio (PAPR) implementing techniques for providing efficient operation at average power levels. Several techniques have been implemented over the past few decades to efficiently amplify high PAPR signals such Envelope Tracking, Doherty, EER [2], [3], [4] and sometimes a mixed approach of these techniques. In conventional transmitter architectures, signal modulation and DC-RF energy conversion (by PA's) are implemented as separate building blocks of the overall system.…”

“…This effect leads to the operation of the amplifier at back-off levels below saturation to ensure signal integrity (linearity) and by doing so the efficiency is degraded considerably. This implies that the PA must be designed for high PAPR implementing techniques for providing efficient operation at average power levels [1].…”
