Title:
METHOD FOR DESIGNING SAW RESONATOR AND COMPUTING DEVICE-READABLE RECORDING MEDIUM ON WHICH METHOD IS RECORDED
Document Type and Number:
WIPO Patent Application WO/2023/128416
Kind Code:
A1
Abstract:
The present invention is for providing a method for designing an SAW resonator and a computing device-readable recording medium on which the method is recorded, wherein, instead of directly measuring characteristics of SAW of the SAW resonator, a 4-port transmission line model for an SAW IDT electrode is established, and parameters of the 4-port transmission line model are calculated by using an initial parameter measured from a sample of the SAW resonator, thereby configuring an SAW filter over a wide frequency band from hundreds of MHz to several GHz.
