Power Amplifier Backoff at Marjorie Lockett blog

Power Amplifier Backoff. −wide bandwidth envelope amplifier supplies vdd bias (drain current) to rf pa. Both the output backoff (opbo) and input backoff (ipbo) are used to determine the operating power levels required in a satellite transponder twta. Power backoff in an amplifier is a power level below the saturation point at which the amplifier will continue to operate in the linear region even if there is a slight. That is, 1 db more input power yields only 0.5 db of output. Envelope tracking (et) consists of two amplifiers. As you drive an amplifier with more input power, the output compresses. In a power amplifier, a measure of how far you must reduce the input power in order to receive the desired output linearity and. The doherty pa relies on a circuit technique to achieve high efficiency in the backoff region, where the signal spends most of its time. It also shows how to examine the power distribution of the signal input.
