With the in-depth advancement of the fifth generation (5G) mobile communication technology, the technical requirements for filters are also constantly improving. Surface acoustic wave (SAW) filters are widely used in home TV, mobile communications, radio frequency filters and radar due to their simple structure, few mask layers, easy miniaturization, and low cost. Through the continuous improvement of communication technology, SAW has developed into various high-performance acoustic filters from bulk SAW with the support of some new architectures, new materials and advanced modeling techniques. This paper analyzes and reviews the research situation of SAW filter technology.
随着第五代（5G）移动通信技术的深入推进，对滤波器的技术要求也在不断提高。表面声波（SAW）滤波器因其结构简单、掩膜层数少、易于小型化且成本低，而广泛应用于家用电视、移动通信、射频滤波器和雷达中。通过通信技术的不断进步，在一些新架构、新材料和先进建模技术的支持下，SAW已从体声波SAW发展成为各种高性能声学滤波器。本文对SAW滤波器技术的研究现状进行了分析和综述。
