CONSTITUTION: A baseband processing unit(50) receives digital signals to filter a predetermined frequency band, and converts the digital signals into analog signals to output the converted signals. A modulation unit(23) modulates and outputs the analog signals. An RF(Radio Frequency) up-converter(24) receives output signals of the modulation unit(23) and a corrected gain signal to output RF signals. An AGC(Automatic Gain Control) unit(70) compares the signals of the baseband processing unit(50) with the output signals of the RF up-converter(24), to output a transmission power correction gain value. In the AGC unit(70), a baseband transmission power detector(25) detects the digital signals of the baseband processing unit(50). A filter(26) receives outputs of the baseband transmission power detector(25) to output an average value. An automatic gain controller(27) receives output signals of the filter(26) to compare the received signals with the digital output value of the RF up-converter(24), to operate the transmission power correction gain value. And a digital/analog converter(29) converts the digital signals of the automatic gain controller(27) into analog signals.
