Abstract :
A simple analysis of two types of two-port SAW resonators composed of series-connected IDTs and parallel-connected IDTs are presented. One type is where the series-connected IDTs are used for transmitter and parallel-connected IDTs are used for receiver. Another type is where parallel-connected IDTs are used for transmitter and series-connected IDTs are used for receiver. These types of resonator have a feature of impedance transformer performance. We have analyzed these types of resonator by six-port equivalent circuits and transfer matrices of N-pair IDT using force factors developed in previous papers.
