Patent ID: 8362837

Claim:
A system for amplifying an input signal, the system comprising: a measurement circuit arranged to measure at least a current power level of the input signal; multiple non-linear power amplifiers; wherein different non-linear power amplifiers are associated with different power ranges; a control circuit arranged to: (a) select at least one selected non-linear power amplifier to be used to amplify a second signal based on at least: the current power level of an input signal; an association between the different power ranges and the different non-linear power amplifiers; an identity of at least one previously selected non-linear power amplifier that was selected during a previous selection process; and (b) assist in an activation of the at least one selected non-linear power amplifier; and a signal processing module, configured to process the input signal to provide the second signal such as to at least partially compensate for a non-linearity of each of the at least one selected non-linear power amplifier.
