Abstract
An arrangement for controlling a high-frequency power amplifier, including a high-frequency power amplifier, a feedback line between the input side and the output side of the high-frequency power amplifier, a control connected to the input side of the high-frequency power amplifier and communicating with the feedback line, a sampler and a detector connected to the feedback line between the output side and the input side of the high-frequency power amplifier, as well as a switch connected to the forward line for bringing the high-frequency power amplifier to an OFF state controlled by a control signal. A parallel loop provided with a reference voltage feed is connected to the feedback line. The loop includes a signal adapter, the transfer function of which is dimensioned to substantially correspond to the transfer function of a power control loop constituted by the forward line and the feedback line, measured at switching points of the parallel loop.
