Abstract
An apparatus and a method for controlling a bias adaptation bias of a high power amplifier. In the high power amplifier, a coupling operation is performed with respect to an input signal with a predetermined voltage, an amount of attenuation used for attenuating a voltage of the coupled input signal is adjusted corresponding to the voltage of the input signal, a bias adaptation bias is created correspondingly to a voltage obtained by attenuating the voltage of the input signal by the amount of the attenuation, and the coupled input signal is amplified corresponding to the bias adaptation bias, thereby performing a signal amplifying operation for maintaining linearity of an input signal, regardless of an average input voltage intensity of the input signal.
