Abstract: A system for multi-distributed amplification of a communication signal including at least one plurality N of input pathways connected to an input Butler matrix which delivers as output N distributed signals, a plurality N of tube amplifiers which receive as input said distributed signals and produce as output N amplified and phase-shifted signals each of a complex gain Gi and an output Butler matrix which receives as input said amplified signals and produces as output N output signals, wherein the phase error and amplitude error are self-compensated in the presence of traffic.
