Claim:
1. A mobile phone comprising: a high-frequency switching circuit comprising a high-frequency switching transistor, wherein a high-frequency signal-path between a high-frequency signal receiver or transmitter and a high-frequency antenna of the mobile phone extends via a channel-path of the high-frequency switching transistor; a control circuit, 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; and a processor, wherein the processor is configured to provide the control signal to the high-frequency switching circuit, depending on a state of the mobile phone; wherein the processor is configured to provide the control signal such that intermodulation distortions of the mobile phone are lower, when the mobile phone is in a first state than in a second state; and such that a current consumption of the mobile phone is lower, when the mobile phone is in the second state than in the first state; and wherein the first state is an UMTS mode and wherein the second state is a GSM mode.
