Abstract

The impedance of a variable load is matched to the output resistance of an HF generator by performing a first impedance matching for a first load impedance and by performing a second impedance matching for a second load impedance. The first impedance matching is carried out at a first frequency and the second impedance matching is carried out at a second frequency.
