1. A method of generating a radio frequency signal based on a baseband signal, the method comprising:

  • modifying the baseband signal by adding an offset signal to the baseband signal, the offset signal being configured to prevent the modified baseband signal from entering a first signal region;

    providing an amplitude signal and a phase signal based on the modified baseband signal;

    modulating the phase signal to a carrier frequency and amplifying the modulated phase signal according to the amplitude signal to generate a preliminary radio frequency signal; and

    feeding an offset compensation signal derived from the offset signal into the preliminary radio frequency signal to generate the radio frequency signal, wherein the offset compensation signal is configured to at least essentially cancel a distortion component, which corresponds to the offset signal, in the preliminary radio frequency signal.
