Abstract

A circuit for generating a radio frequency signal includes an amplifier configured to provide a radio frequency signal, the radio frequency signal being based on a baseband signal and a power supply configured to provide a variable supply voltage to the amplifier. A predistortion circuit is configured to modify the baseband signal; and a control circuit configured to control an operation mode of the predistortion circuit depending on a bandwidth of a radius of the baseband signal.
