ABSTRACT:
In order to realize control of a transmission signal level from a radio transmitter of TDMA (Time Division Multiplex System) with a simplified arrangement and with a high precision, a control circuit 9 outputs a transmission signal for each time slot and a level designation signal. A level control signal generator circuit 4 generates a level control signal in response to the level designation signal and outputs the level control signal through D/A converter 5 to a level control circuit 2. The level of the modulated transmission signal is controlled by the level control circuit 2 and is amplified by a RF amplifier circuit 3 thereby being output outside. The output level is detected by a detector circuit 8 and fedback through A/D converter 7 and a detection characteristic storage circuit 8 to level control signal generator circuit 4 so that the value of the level control signal is corrected.
