Abstract
Power amplifier apparatus comprising a power amplifier () having a signal output, and a power control feedback loop () for controlling the output signal power relative to a first power target signal (). A saturation control loop () is responsive to a parameter indicative of saturation of the power amplifier () for adjusting the output signal power to a level at which the power amplifier means is substantially not saturated. A power target variation module () operable when the first power target signal () is at or close to a value corresponding to saturation of the power amplifier means () applies to the power control loop (to) a modified power target signal () corresponding to a power target higher than the first power target signal () and at which the power amplifier means () saturates. The modified power target signal () causes the saturation control loop () to react to saturation of the power amplifier means () adjusting the output signal power to a level at which the power amplifier means () operates substantially at its maximum power but not saturated.
