Abstract
According to the invention, the high-frequency power amplifier is characterised in that the power transistor is switched in such a way that said transistor is operated in the breakdown region and that a control loop is provided. Charge carriers that are produced is the breakdown region are carried away from an output of the operational amplifier by means of said control loop.
