Title:
SAW RESONATOR DESIGN METHOD, SAW FILTER AND DESIGN METHOD THEREFOR, AND COMPUTING DEVICE-READABLE RECORDING MEDIUM HAVING SAME RECORDED THEREON
Document Type and Number:
WIPO Patent Application WO/2023/128417
Kind Code:
A1
Abstract:
The present invention relates to a SAW resonator design method, a SAW filter and a design method therefor, and a computing device-readable recording medium having same recorded thereon, which may improve a quality factor of the SAW resonator by designing a structure, such as an input IDT finger, an output IDT finger, and an interval between fingers in an IDT electrode of the SAW resonator under optimal conditions without changing a material of the SAW resonator or changing a manufacturing process, and may obtain reduced insertion loss and improved frequency characteristics by configuring the SAW filter by using the SAW resonator described above.
