ABSTRACT:
A digitally operating switching amplifier for direct and alternating voltage that is suitable as a modulation amplifier for radio transmitters with anode modulation. The power portion of the amplifier consists of cascade-connected, controllable, peak current-limited partial voltage sources that are connected via a low-pass filter to a load resistor, which is the high-frequency output stage in a radio transmitter. The control of peak current-limited partial voltage sources, some of which present differing voltage values, is effected in such a manner that a high degree of efficiency is attained and that distortions of the modulation signal are small.
