移动终端中的射频滤波主要是基于声表面波（SAW）和体声波（BAW）的滤波器，因为它们具有高性能、小尺寸和低成本。与 SAW 滤波器技术相比，BAW 滤波器解决方案可以提供更低的插入损耗、更好的选择性、更高的功率处理能力、更高的工作频率和更好的 ESD 保护。凭借这些优势，BAW滤波器技术在无线通信应用中赢得了更多的市场份额。
RF filtering in mobile terminals is dominated by surface acoustic wave (SAW) and bulk acoustic wave (BAW) based filters due to their high performance, small size, and low cost. As compared to SAW filter technology, BAW filter solutions can provide lower insertion loss, better selectivity, higher power handling, higher operation frequency, and better ESD protection. With these advantages, BAW filter technology has been gaining more market share in wireless communication application.
