Title:
A FACILITATING FAULT TOLERANCE IN A RF AMPLIFIER SYSTEM
Document Type and Number:
WIPO Patent Application WO2004095687
Kind Code:
A3
Abstract:
N input signals are fed (702) to a first Fourier Transform Matrix (FTM) (208) to produce N intermediate signals. Each of the N intermediate signals is split (704) via a non-isolating splitter (300) to produce M split signals. At least one of the M split signals from each of the N intermediate signals is amplified (706) to produce at least N amplified signals. The at least N amplified signals are coupled (708) to N non-isolating combiners (300), each having at least M input ports, to produce N combiner output signals. The N combiner output signals are applied (710) to a second FTM (210) to produce N final output signals.
