Abstract

Surface Acoustic Wave (SAW) devices play an important role in telecommunication systems and are widely used as electronic filters, resonators, actuators and oscillator. SAW resonator consists of metallic structures of interdigitated transducer (IDT) deposited on piezoelectric substrate. The geometry of IDT will affect the resonator's characteristic. There are several methods for modeling and analysing SAW devices include the impulse model, the equivalent circuit model, the coupling-of-mode (COM) model and matrix model. This project focused on the modeling of circular SAW resonator using equivalent circuit technique. Curve fitting between the lumped element circuit and S11 measurement of two resonator designs was demonstrated using AWR Design Environment software. Based on the results, it shows that the frequency response from the equivalent circuit model agrees well with experimental measurement of each device. This project comes out with the optimum equivalent circuit that is suitable for circular SAW resonator.
圆形表面声波(SAW)谐振器的电路建模
表面声波(SAW)器件在通信系统中起着重要的作用,被广泛用作电子滤波器、谐振器、致动器和振荡器。声表面波谐振器由沉积在压电衬底上的互指换能器(IDT)金属结构组成。IDT的几何形状会影响谐振器的特性。对声表面波器件进行建模和分析的方法有脉冲模型、等效电路模型、模式耦合模型和矩阵模型。本课题的重点是利用等效电路技术对圆形声表面波谐振器进行建模。利用AWR Design Environment软件演示了两种谐振器设计的集总元件电路与S11测量之间的曲线拟合。结果表明,等效电路模型的频率响应与各器件的实验测量值吻合较好。本文提出了适合圆形SAW谐振器的最佳等效电路。
