Abstract: There is provided an RF amplifier arrangement comprising: an input operable to receive an RF input signal; an output operable to output an amplified RF signal; at least one amplifier bank located between the input and output, the or each amplifier bank comprising a plurality of amplifier stages; an input level detector operable to measure the signal level of the RF input signal; and a controller operable to control the amplifier bank, wherein the controller is operable to select one or more different configurations of the amplifier by selecting one or more amplifier stages and/or modifying one or more characteristics of one or more amplifier stages in dependence upon the signal level of the RF input signal to dynamically adapt and optimise its characteristics.
