本文讨论了可调谐射频 (RF) 表面和体声波 (SAW/BAW) 滤波器的可能性。首先，对当前无线通信系统中射频前端的配置进行了综述，并讨论了灵活射频前端和软件定义无线电（SDR）的研究趋势。其次，介绍了各种射频可调谐滤波器，并讨论了在上述关键技术得到开发的情况下，可调谐射频SAW/BAW滤波器如何实现高性能。最后，我们解释了我们的项目中正在进行哪些类型的研究主题，以实现 SDR 的灵活射频前端。
This paper discusses possibilities of tunable radio frequency (RF) surface and bulk acoustic wave (SAW/BAW) filters. First, configuration of RF front-end in current wireless communication systems is surveyed, and research trends of the flexible RF front-end and software defined radio (SDR) are discussed. Second, various RF tunable filters are introduced, and we discuss how high performances are expected by the use of tunable RF SAW/BAW filters provided that above mentioned key technologies are developed. Finally, we explain what kinds of research subjects are going on in our projects for realization of the flexible RF front-end for the SDR.
