Abstract: In a preferred embodiment, a low distortion power sharing amplifier network capable of amplifying a plurality of input signals includes a plurality of amplifiers, each for amplifying an approximately equal amount of RF signal power. The power sharing arrangement prevents any one of the amplifiers in the network from operating too deep into saturation even when the plurality of input signals vary widely in power. Distortion is reduced by coupling at least one feed-forward loop to the amplifier network.

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.
