Abstract
A communication unit has an envelope tracking system operably coupled to a power amplifier, PA, module. The envelope tracking system has at least one slew rate module arranged to re-distribute a slew rate across a number of input samples according to a maximum slew rate of the number of input samples; and a supply modulator arranged to variably control a supply voltage for the PA module in response to an output of the at least one slew rate module.
