Abstract:
1. A power consumption controlling apparatus for controlling power consumption of a high frequency amplifier, which amplifies a high frequency transmitting signal, to reduce the power consumption by adjusting a power supply voltage and a bias voltage of the high frequency amplifier, the power consumption controlling apparatus comprising: a receiving circuit for receiving the high frequency transmitting signal amplified by the high frequency amplifier; an evaluating section providing an evaluation by evaluating whether or not a receiving signal obtained from the receiving circuit satisfies a predetermined quality; a transmitting power measuring circuit providing a measured power by measuring power of the high frequency transmitting signal; a power consumption measuring circuit providing a measured power consumption by measuring the power consumption of the high frequency amplifier; and an adjusting section for adjusting the power supply voltage and the bias voltage to maximize efficiency of the high frequency amplifier, where the efficiency being found is based on the measured power, the measured power consumption, and the evaluation.
