SH mode on SiO2/Al/LiNbO3 structure is studied because of their sufficient electromechanical coupling factor (K2) and good temperature coefficient of frequency (TCF). Authors proposed the suppression method of the spurious response of the Rayleigh mode and the transverse mode for the narrow duplex gap application. For the narrow duplex gap application, SiO2 thickness must be increased to achieve the...
This paper describes a suppression of transverse-mode spurious responses for zero temperature coefficient of frequency (TCF) surface acoustic wave (SAW) resonator on a SiO2/Al/LiNbO3 structure. We investigated to use thinning of SiO2 on the dummy electrodes and studied how the transverse-mode responses change with remaining SiO2 thickness h on the dummy electrode region. As the results, we could realize...
A SiO2/Al/LiNbO3 structure has a large electromechanical coupling factor (K2) and good temperature coefficient of frequency (TCF) for the UMTS Band I application. However, the SiO2/Al/LiNbO3 structure also supports two unwanted spurious responses; one is caused by the Rayleigh-mode and the other by the transverse-mode. As the authors have previously discussed, the Rayleigh-mode spurious response can...
