ABSTRACT:
A method and a device for tuning power amplifier (PA,203) properties such as back-off. A peak-to-average value (PAR) of the amplifier input signal is first obtained by control means (206) and then used for adjusting the power amplifier (203) with tuning means (204, 208, 210) functionally connected to the amplifier (203). The suggested solution is advantageously exploited in a wireless communications device like a mobile terminal to optimize the performance thereof by, for example, reducing the power dissipation in the transmitter.
