Abstract

A high-frequency switching circuit includes a high-frequency switching transistor, wherein a high-frequency signal-path extends via a channel-path of the high-frequency switching transistor. The high-frequency switching circuit includes a control circuit and the control circuit is configured to apply at least two different bias potentials to a substrate of the high-frequency switching transistor, depending on a control signal received by the control circuit.
