1. A transmission power amplifier device comprising:

  • a power amplifier including a GaAs FET;

    means for storing the relation between predetermined information of the gate voltage of said GaAs FET and the transmission power amplification efficiency for each of individual channels;

    means for reading out from said storage means the predetermined gate voltage information corresponding to each of said channels;

    means for generating a DC voltage on the basis of the gate voltage information read out from said storage means;

    means for generating a fixed voltage; and

    means for adding said fixed voltage to said DC voltage and applying the sum voltage to the gate of said GaAs FET.
