摘要:

随着用户数量和连接设备数量的不断增长,移动通信的数据速率和数据量持续攀升。随着5G和6G部署在即,无线通信正朝着更高频率和更大带宽的方向发展,从而实现更高的速度和吞吐量。当前的微声学谐振器技术是射频前端滤波器中的关键部件,但正难以跟上这些发展步伐。本工作提出了一种新颖的声学谐振器架构,能够为位于3 GHz以上的5G及未来6G频段实现多频率、低损耗和宽带滤波。得益于这些谐振器的卓越性能,本文展示了用于5G n77和n79频段的滤波器,其分数带宽分别达到13%和25%,插入损耗低至约1 dB。凭借其独特的频率可扩展性和宽带能力,所报道的架构为未来移动设备中的滤波和多路复用提供了一种有前景的选择。

英文摘要:

Data rates and volume for mobile communication are ever-increasing with the growing number of users and connected devices. With the deployment of 5G and 6G on the horizon, wireless communication is advancing to higher frequencies and larger bandwidths enabling higher speeds and throughput. Current micro-acoustic resonator technology, a key component in radiofrequency front end filters, is struggling to keep pace with these developments. This work presents a novel acoustic resonator architecture enabling multi-frequency, low-loss, and wideband filtering for the 5G and future 6G bands located above 3 GHz. Thanks to the exceptional performance of these resonators, filters for the 5G n77 and n79 bands are demonstrated, exhibiting fractional bandwidths of 13% and 25% respectively with low insertion loss of around 1 dB. With its unique frequency scalability and wideband capabilities, the reported architecture offers a promising option for filtering and multiplexing in future mobile devices.
