초록

Effect of IDT structures on the frequency response of the SAW device are investigated. Various types of IDTs, such as MSC(multistrip-coupler), double split, reflector, and ground line. are designed and patterned on the widely used Y-Z cut LN$(LiNbO_3)$ substrate. Center frequencies, band widths, and insertion losses are measured and compared. Invalidity of the conventional model based on the impulse response model is also discussed.
