摘要
Abstract
Electric tuned filter has been widely used and developed in RF receiving field for its low cost,compact structure and steady tracking performances. In this paper, an improvement of the electric tuned filter is introduced by analyzing the coupling factor effect to the circuits. It eliminates the changefully shortage of the coupling factor when the tune filter applies to a wideband situation, compares with the customary method the filter performance is greatly improved. ADS simulation and testing results prove that the design method is correct.关键词
