Abstract
A power amplification controlling apparatus and method in a mobile communication system are provided. An amplifying part amplifies an input Radio Frequency (RF) signal with a power supply voltage. A bias adaptation part detects a change in at least one an operation and an environment of the amplifying part, attenuates the RF signal according to the detected change, detecting the envelope of the attenuated signal, and generates a supply voltage control signal according to the envelope. A power supply part changes the power supply voltage in response to the supply voltage control signal.
