Abstract
A power consumption controlling apparatus controls power consumption of a high frequency amplifier to reduce the power consumption by adjusting a power supply voltage and a bias voltage of the high frequency amplifier which amplifies a high frequency transmitting signal. The power consumption controlling apparatus includes: a receiving circuit for receiving the high frequency transmitting signal amplified by the high frequency amplifier; an evaluating section for evaluating whether or not a receiving signal obtained from the receiving circuit satisfies a predetermined quality; and an adjusting section for adjusting the power supply voltage and the bias voltage in a range in which the receiving signal evaluated by the evaluating section satisfies the predetermined quality.
