ABSTRACT:
An RF amplifier includes at least one RF amplification stage having an RF input signal and an RF output signal and a power signal circuit with power supply coupled with the amplification stage for providing a power signal to the amplification stage.A bias circuit biases the amplification stage to control its operation.A pulse detection circuit is coupled with the power signal circuit and the bias circuit and detects a voltage from the power signal.The pulse detection circuit analyzes the detected voltage of the power signal and determines if the RF input signal presents a pulsed signal condition or non-pulsed signal condition, and controls the bias circuit for biasing the amplification stage according to the determined condition.
