Abstract
A device for controlling the biasing of an amplifier receives an input signal to be amplified and a bias signal and supplies an amplified output signal. The amplifier has at least two separate possible power output values and the amplified output signal is principally in a predetermined frequency band. The device includes a circuit for controlling the biasing of the amplifier which receives linearity control information and generates the bias signal in accordance with the linearity control information so that an actual out-band send level is substantially equal to the required out-band send level. The actual out-band send level is defined as a send level of the amplified output signal outside the predetermined frequency band. The required out-band send level is defined as a predetermined maximal out-band send threshold level for any of the separate possible output power values.
