Equivalent four-port networks for series connected SAW-IDT and their application
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 LiNbO/sub 3/ (128/spl deg/ Y,X) are investigated.
