<p>A transmission power control circuit comprises a control data table (56) in which digital data of monitor voltage depending on a transmission power level for a plurality of values of transmission frequency and a plurality of values of transmission power are stored, and a D/A converter (62) for converting selected values of the digital data to an analog signal as a reference voltage. The transmission power is controlled so that the monitor voltage becomes equal to the reference voltage.</p> |
