| Abstract(in English) | This report discusses how performances of single-phase unidirectional transducers (SPUDT) for surface acoustic wave (SAW) devices are influenced by their design parameters with a help of the ρ matrix method and the coupling-of-modes (COM) theory. It is shown that the reflection coefficient ρ_11 of the SPUDT is determinative for the behavior of the SPUDT. Since the acoustic length of SPUDTs is required to be short so as to realize better group delay characteristics, the reflectivity per SPUDT unit cell is required to be large so as to realize better passband and transition band characteristics. |
