移动通讯用声表面波器件发展近况

Overview of low loss SAW filters for mobile communication applications

本文首先回顾了民用声表面波器件的最新发展概况．随着移动通讯的发展，声表面波器件的最大应用市场将是通讯，而低插损声表面波滤波器成为新的研究高潮．本文因此随后简要介绍了几种主要的低插损结构的研究情况及其在移动通讯中的应用．最后，展望了声表面波器件的发展趋势．

This paper first reviews the current status of SAW devices. With the rapid growth of mobile communication, the largest SAW application will be for communitions by 2000 and low loss filters have been new focus of research and developmemt. Then, an overview of filter technique available for different applications is given. Finally, future trends for SAW devices research and development is predicted.
