Thin-film lumped-element microwave filters

A method for the design and construction of thin-film lumped-element microwave filters is presented. The resulting filters exhibit broad spurious-free stopbands, small physical size, excellent amplitude and phase match, and high reliability due to their thin film construction. The necessary models for inductors and capacitors are discussed. Multilayer thin-film techniques make the construction of these filters efficient and cost-effective. Experimental results on several filters are presented.<<ETX>>
