PURPOSE: A method for simultaneously calibrating a band and a channel of a mobile communication terminal is provided to integrate calibrations separated by band and channel, and to simultaneously calibrate the bands and the channels. CONSTITUTION: A terminal adjusts frequencies in accordance with predetermined channels, and sets the channels(201). The terminal calibrates changed power values, and sets channel calibration powers(202). The terminal sets scale factors(203). If the scale factors are successfully set, the terminal sets a ramp(204). The terminal transmits a calibrated frequency to a transmission end to perform a power amplification, and transmits an amplified power to an antenna(205). A power amplifier of the transmission end amplifies the frequency so as to be a proper transmission frequency, and transmits the amplified frequency through the antenna(206).
