Title: Automatic level controlling circuit
Inventor: ONO KUNIHARU
IPC: H03G3/30
Filed: 1985-04-10
Abstract: PURPOSE:To prevent related circuit parts from being damaged when one of plural power amplifiers becomes abnormal, by calculating the level difference of detecting signals obtained by means of a current detecting means and controlling an automatic level controlling (ALC) loop by using the calculated value. CONSTITUTION:When distributed high-frequency signal power increases from a level E1 to another level E2 in detecting signals, an ALC signal is produced at the output terminal PZ of an arithmetic circuit 7. Therefore, an ALC loop controls the variable amplifier of a transmitter 2 so that the ALC signal can become '0'. Therefore, the distributed high-frequency signal power decreases until the detecting signal converges to the level E2. When one of power amplifiers A1-An becomes defective and the detecting signal does not work normally at levels higher than a level EX which is lower than the level E1, the variable amplifier of the transmitter 2 is controlled so that the high-frequency signal power distribute to all the power amplifiers A1-An can become the level EX in detecting signal.
