A transmission electric power control device includes: a coupler 12, detector 13, electric power amplifier 14, error detection means 15, target value generation means 16, gain variable means 17, control calculation means 18, control calculation parameter generation means 19, modulator 20, control variable addition means 21, transmission electric power control means 22, and transmission electric power designation means 23. In this case, the automatic transmission electric power control feedback loop includes: the coupler 12, detector 13, error detection means 15, control calculation means 18, control calculation parameter generation means 19, transmission electric power designation means 23, control variable addition means 21 and gain variable means 17. When the control calculation parameter in the automatic transmission electric power control feedback loop is made variable according to the transmission electric power designation information and also when the convergence offset value of the loop response characteristic is made variable, it is possible to conduct an electric power control of a high dynamic range, high linearity and high accuracy even if the electric power source control of the electric amplifier is conducted for each transmission electric power and the gate bias control is conducted.
