Patent ID: 7983636

Claim:
An amplifier control device which receives and amplifies a transmission signal having a property of a burst, comprising: an attenuation device which attenuates an output signal of the amplifier to a level before amplification and which outputs the signal; an error signal accumulation value calculation device which starts calculating a difference between the transmission signal and a signal output from the attenuation device, as an error signal accumulation value, when a transmission signal input to the amplifier rises from OFF to ON; and a bias control device which controls a bias voltage to be applied to the amplifier based on the error signal accumulation value calculated by the error signal accumulation value calculation device and which sets a start timing of the bias voltage based on the error signal accumulation value, wherein the bias control device reports a completion of setting of the start timing to the error signal accumulation value calculation device when the bias control device completes the setting, and the error signal accumulation value calculation device stops the calculation when the error signal accumulation value calculation device receives the report from the bias control device.
