摘要： A power control system includes a reference path filter used to suppress high frequencies in an input signal and generate a filtered envelope signal, a reference path amplifier to scale the filtered input signal based on a gain signal and generate a reference signal, a signal path amplifier to amplify an RF modulated signal and generate a signal path output signal scaled by a gain of an actuator signal, and a power detector to detect a power associated with the signal path output signal. The system includes an ADC to receive, pre-filter and convert the detected envelope signal into a measurement signal, and a comparator block to receive the reference signal and the measurement signal, and generate an error signal based on the difference, and a controller to generate the actuator signal for controlling the gain of the signal path amplifier based on the error signal.

摘要： An amplitude modulator is provided, which has a first supply connection for supplying a supply potential and a second supply connection for supplying a ground potential. An amplifier stage with a push-pull output stage has a signal input for supplying a signal, and has a single-pole output for emitting a single-ended signal. In order to supply the push-pull output stage, the amplifier stage is connected in a supply path between the first and the second supply connection. A first controllable voltage source and a second controllable voltage source are also provided, whose control inputs are connected to a connection for control purposes by means of a differential modulation signal, and are connected between the amplifier stage and the first supply connection, or the amplifier stage and the second supply connection. Amplitude modulation is thus achieved by modulation of the supply voltage or of the supply current to the push-pull output stage.
