ABSTRACT:
The amplification efficiency is increased in a system for linear amplification of signals, especially in satellite transponders, by connecting at least three amplifier impedance inverter units in parallel to each other between an input signal control network and a common load. The reactive loading of the individual amplifiers is compensated by shunt susceptances at the output ports of the individual amplifiers.
