【摘要】 国外有学者提出了一种延迟线失配法来提高前馈放大器的效率。为了更全面考察这种方法对于前馈放大器单环抑制性能,尤其是误差环路的抑制性能的影响,从幅度、相位误差以及延迟线失配3个方面进行了仔细全面地分析,并得出了相应的结论。更多还原

【Abstract】 A foreign scholar has brought forward some kind of delay mismatch method to improve the efficiency of feedforward amplifiers. In order to observe the effect on cancellation performance of linearization loop of feedforward amplifiers, especially on cancellation performance of error cancellation loop, this article analyzes the method carefully and completely from magnitude error, phase error and delay mismatch, and gets corresponding conclusions.更多还原
