A power amplifier arrangement includes a power divider for dividing the signal to be amplified into equal-amplitude components. Each component is amplified by a signal amplifying path. The amplified signals are applied to a phase-sensitive power combiner. The combined signal appears at the sum port and...http://www.google.fr/patents/US5222246?utm_source=gb-gplus-shareBrevet US5222246 - Parallel amplifiers with combining phase controlled from combiner difference port
