概要

• 論文の詳細を見る

• We propose a novel adaptive linearization technique for a balanced-amplifier array. The technique uses the specific intermodulation distortions (IMDs) at the output ports in the array. The detected IMD power level can be used to optimize the linearizer's characteristics. Because the design does not need as many power detectors and carrier cancel loops as it does amplifiers, we were able to successfully miniaturize the array-antenna system. This paper describes the principles, verified both experimentally and mathematically for a 4-port amplifier array.
