Abstract
A power amplifier unit for a transmitter in a mobile communication system is set up so that the operational point of the power amplifier varies in dependence on the instant power level of its input signal. This is used in the context of a variable envelope input signal such that a constant gain of the power amplifier can be achieved by this feedback.
