Abstract
A method of controlling a transmission power in a CDMA system in which an AGC (automatic gain control) amplifier that amplifies a transmission signal, and an RF power amplifier that amplifies an output of said AGC amplifier are disposed, and a gain of said AGC amplifier is controlled by a transmission power control signal to control a transmission power, wherein first comparing means for comparing-the transmission power control signal with a predetermined reference value, and second comparing means for detecting the transmission power, and for comparing the detected transmission power with a predetermined reference value are disposed, and when only said first comparing means outputs an output signal, a signal in a direction along which the transmission power is increased is produced, and, when only said second comparing means outputs an output signal, a signal in a direction along which the transmission power is decreased is produced and the signal is added as an offset signal to the transmission power control signal, and, when both said first and second comparing means output an output signal or when both said first and second comparing means do not output an output signal, a present offset signal is held.
