摘要： Disclosed herein is a power amplification module for a mobile communication terminal. The power amplification module includes a balanced power amplifier configured to divide an input signal using a phase difference, amplify resulting signals, and combine the amplified signals with each other, and a transmission power detection unit connected to an isolation terminal formed on an output side of the balanced power amplifier and configured to amplify a micro-power signal, which is transmitted to the isolation terminal from an outside of the transmission power detection unit, and to transmit the amplified signal. Accordingly, since the detection signal to input terminal and detection signal output terminal of a transmission power detection unit can be easily implemented using an internal circuit, the entire size of the power amplification module can be reduced. Further, characteristic of isolation between the detection signal input terminal and the detection signal output terminal can be improved.
