Abstract
A wireless communication unit comprises a transmitter having an analogue feedback power control loop with an input and a power amplifier having a power amplifier output, where the analogue feedback power control loop is arranged to feedback a signal to the input to set an output power level of the transmitter. The wireless communication unit further comprises an outer digital loop operably coupled from the power amplifier output to the transmitter.In this manner, the inner analogue loop is used to linearise a response obtained from the power amplifier and an outer digital loop wherein the outer digital loop controls the inner analogue loop with regard to saturation detection and correction as well as facilitating multi-mode operation of the wireless communication unit.
