In the present invention, the power unit and its power-management method and a wireless communication terminal has a bar, the wireless communication terminal to provide a baseband operation unit, a radio frequency operation unit and the baseband operation unit and the radio frequency operation the direct current power source is connected to both the unit containing the converter, and also includes a power supply, CPU, and envelope detection unit; The power supply unit receives the voltage provided by the DC power converter provides an output voltage to the PA in the radio frequency operations unit, and further receives a control signal to the CPU is transmitted, and controls the output voltage by the control signal causes the output voltage set to thereby meet the envelope variation curve of the output signal of the PA, and; Envelope detection device is set up to check the envelope signal of the PA output signal in real time and to transmit the envelope signal to the CPU; CPU is set to receive a voltage provided by the DC power converter, and switching the sikimyeo envelope signal to the envelope detection unit transmits a control signal, to transmit the control signal to the power conversion device. Method of the present invention can solve the problems of power consumption and heat dissipation PA.
