Abstract

In a preferred embodiment, an apparatus for amplifying a plurality of input signals is provided, including a power sharing amplifier network and a redistribution circuit. The power sharing amplifier network includes first and second distributing networks and a plurality of amplifiers coupled therebetween. Each amplifier amplifies a composite signal having an approximately equal amount of signal power from all of the input signals. The first distributing network receives and splits up the input signals, whereas the second distributing network receives and recombines the amplified signals from the amplifiers to provide amplified output signals, each corresponding to one of the input signals. The redistributing circuit provides a redistribution signal derived from the input signals, which is applied to the first distributing network. The amplitude and phase characteristics of the redistribution signal are such that when it is split up by the first distributing network, it vectorially combines with the composite signals so as to reduce peak envelope power within at least one composite signal.
