METHOD AND CIRCUIT FOR DISTORTION COMPENSATION AND OUTPUT CONTROL |
摘要 |
<p>A distortion compensation output control circuit has an adder 1 for adding a value of input electric power and a value of a part of output electric power negatively fed backed together, a variable attenuator 2 for attenuating the electric power output from the adder 1, an electric power amplifier 3 for amplifying the electric power output from the variable attenuator 2 and outputting the output electric power set to a prescribed value, a variable attenuator 4 for attenuating the output electric power output from the electric power amplifier 3 and negatively feeding back the attenuated output electric power to the adder 1, a control circuit 12 for controlling the variable attenuator 4 so as to obtain the output electric power of the prescribed value, and a control circuit 11 for controlling the variable attenuator 2 so as to obtain a loop gain depending the output electric power of the prescribed value. <IMAGE></p> |
