摘要：
Method for operating an RF power amplifier (100; 200) with an approximately linear characteristic by adjusting at least one operating parameter of the amplifier or at least one active component of this amplifier, wherein a minimum collector or drain current of the active component or, respectively, an amplifier stage and the input signal level of the RF power amplifier are controlled in dependence on the quotient of harmonic power and useful-signal power of the amplifier output signal.
