Claim 13:
14. An RF front end comprising one or more antennas and one or more amplifiers arranged to amplify signals received by or to be transmitted from the one or more antennas, and one or more power supplies arranged to supply power to each of the one or more amplifiers wherein each power supply comprises:
one or more switches and a driver circuit arranged to control the one or more switches to supply switched power from a power source to an output of the power supply,
one or more inputs to the driver circuit arranged to receive a first periodic switching signal in a first mode of operation and a second switching signal in a second mode of operation, the second switching signal comprising a pulse of a duration longer than the period of the first switching signal,
wherein the driver circuit is arranged to use the first and second switching signals to:
