Abstract
A power control circuit includes a voltage control circuit and a current control circuit. The voltage control circuit is configured to detect an output power control signal that is inputted, convert the output power control signal into a control voltage and output the control voltage to the driver stage of a power amplifier connected to the power control circuit. The current control circuit is configured to detect an output power control signal that is inputted, convert the output power control signal into a control current and output the control current to the amplification stage of the power amplifier.
