Abstract
A transmission electric power control device includes: a coupler detector electric power amplifier error detection means target value generation means gain variable means control calculation means control calculation parameter generation means modulator control variable addition means transmission electric power control means and transmission electric power designation means In this case, the automatic transmission electric power control feedback loop includes: the coupler detector error detection means control calculation means control calculation parameter generation means transmission electric power designation means control variable addition means and gain variable means 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.
