Numerical synthesis of frequency response is discussed for a ladder type filter consisting of ultra-wideband SAW resonators on Cu-grating/15degYX-LiNbO3 structure. For the synthesis, two parameters of each resonator, i.e., the static capacitance and resonant frequency were numerically optimised, while the capacitance ratio and figure of merit were fixed at specific values determined by substrates...
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 width/length weighted dummy electrodes were...
