A switching amplifier, in particular for generating a modulated anode voltage for a high-frequency, high-power AM transmitter, includes a number of switchable voltage sources. The switchable voltage sources in a first portion of the amplifier provide small-scale gradations, which can be combined in any sequence. The switchable voltage sources in a second portion of the amplifier provide large voltage leaps of constant magnitude, which are combined in sequence.
