Claim 0:
1. A method of operating a power amplifier supplying power to an antenna, the method comprising:
in a first mode of operation, supplying switched power to the power amplifier via a driver circuit and one or more switches to switch the supply of power to the power amplifier on and off under the control of a periodic first switching signal; and
in a second mode of operation calibrating the power amplifier, wherein the calibrating comprises supplying voltage to the power amplifier via the same driver circuit and one or more switches under the control of a second switching signal comprising a pulse with a duration longer than the period of the first switching signal,
wherein,
the antenna is a radio frequency “RF” antenna forming part of an RF front end operable in receive and transmit modes,
the power amplifier operates during one of the receive and transmit modes, and
the periodic switching on and off of the power amplifier is timed to switch off the power amplifier during the other of the receive and transmit modes.
