摘要： A high power amplifier system having low electric power consumption and a high dynamic range is provided. The high power amplifier system receives at least one control signal for enabling selection of the maximum current and the minimum current, reference voltage, control voltage for controlling gain and an input signal and then selects the maximum and minimum currents in response to at least one control signal. If the control voltage for controlling gain, that is, the gain of an output signal with respect to an input signal has a high voltage value within a range between the maximum current and the minimum current, the high power amplifier system magnifies the amount of current flowing in an amplification circuit therein. If the control voltage for controlling gain, that is, the gain of an output signal with respect to an input signal is low, the high power amplifier system reduces the amount of current flowing in the amplification circuit. As a result, the high power amplifier system keeps a high dynamic range within a predetermined voltage range of the control voltage and enables a particular amount of current to flow in case the control voltage is over the predetermined voltage range, thereby minimizing the amount of current flowing therein.
