PARALLEL AMPLIFIER ARCHITECTURE USING DIGITAL PHASE CONTROL TECHNIQUES

摘要

An improved method and apparatus for using parallel amplifiers to efficiently amplify an information signal are disclosed. The improved apparatus utilizes digital signal manipulation techniques in optimizing the phase of the upconverted input signals provided to each of the parallel amplifiers. The phase and amplitude of the input signals are adjusted such that the power measured at the output of a combiner (402) is maximized as compared to the sum of the power of combiner (120) input signals. ® KIPO & WIPO 2007
