Abstract :
We have developed the new equivalent four-port network of an N-pair of IDT for electric series connection of IDTs. From this equivalent circuit, we have derived the four-port transfer matrix, which is very useful for the analysis of the SAW devices using series connected IDTs. As a practically useful example, we have analyzed the one-port SAW resonator using connected IDTs. Finally, by numerical calculation, resonance characteristics of this type of resonators on LiNbO3 (128° Y,X) are investigated
