An electrosurgical high frequency (HF) generator for cutting and/or coagulating biological tissue. The generator comprises a power supply and a generator stage for exciting an HF oscillation signal in an output filter comprising a parallel resonant circuit coupled to a series resonant circuit, to which at least one electrode is connected. The generator has an improved efficiency level if the series resonant circuit has a resonance frequency that is higher than the resonance frequency of the parallel resonant circuit.
