Abstract:
    A device is disclosed that includes an amplification part for a linear transmitter, the amplification part being configured to amplify a transmission signal in accordance with a supply voltage control signal; a generation part configured to generate a power supply signal showing the level of the transmission signal; and a control part configured to output the supply voltage control signal based on the power supply signal. The control part includes a storage part configured to store a series of values of the power supply signal belonging to a time range including a certain point of time; and an output part configured to output a maximum one of a predetermined number of values of the series of values of the power supply signal as the supply voltage control signal at the certain point of time.
