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.
Claims8
A SAW resonator design method using characteristic information of a SAW resonator, the SAW resonator design method comprising:
- calculating feature frequency information for a surface acoustic wave generated by an IDT electrode using a scattering coefficient measured from each of SAW resonator samples;
- calculating information indicative of physical properties of the surface acoustic wave in the IDT electrode using the feature frequency information;
- and
- designing a SAW resonator from a transmission line circuit model of the surface acoustic wave using the calculated information indicative of the physical properties of the surface acoustic wave.
