Abstract
A wireless communication unit comprises a transmitter comprising a power amplifier, an inner feedback power control loop having a power control logic module comprising loop priming logic module operably coupled to the power amplifier, and a switchable outer digital loop comprising switchable logic module. The loop priming logic module is arranged to set a power reference value for controlling the power amplifier prior to a ramping operation of the power amplifier and the switchable logic module switching the switchable outer digital loop on or off, thereby restricting adverse transient behavior of the power amplifier.
