This paper describes the development of extremely wideband and very low-loss RF SAW filters of ladder type for future communication systems. Because of its large electromechanical coupling factor for SH-type SAWs, a Cu-grating/15degYX-LiNbO3 structure was employed as a substrate. At first, four-stage ladder type filter was designed and fabricated, where… CONTINUE READING
