Abstract:
A transmission signal power control device includes: at least one low-power attenuator configured to attenuate amplitude of a transmission signal when an absolute value of the amplitude of the transmission signal is smaller than or equal to a clipping threshold; a power amplifier configured to amplify the transmission signal output from the at least one low-power attenuator; and a control unit configured to stop operation of the power amplifier when the absolute value of the amplitude of the transmission signal is smaller than or equal to a value and operate the power amplifier when the absolute value of the amplitude of the transmission signal is larger than the value.
