PFI-TT: Acoustic Filters for 5G Handsets

创新伙伴关系-技术转化（PFI-TT）项目的更广泛影响/商业潜力在于解决新发布的第五代蜂窝网络技术（5G）对移动数据日益增长的需求。我们将开发手机技术来满足这些新的5G要求。拟议的项目旨在克服技术挑战，促进5G系统宽带铌酸锂声学滤波器的转换。铌酸锂薄膜谐振器技术已经能够比任何其他手机滤波器技术增加5倍的可用带宽，同时在小尺寸下保持滤波器损耗最小。该PFI-TT项目将把这些滤波器的工作频率扩展到5G标准所要求的频率，并克服技术挑战，使这种铌酸锂声学谐振器技术能够大规模部署，其带宽是无线电前端声学滤波器带宽的五倍。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact/commercial potential of this Partnerships for Innovation - Technology Translation (PFI-TT) project consists in addressing the growing demand for mobile data in the newly released 5th generation cellular network technology (5G). We will develop handset technology to meet these new 5G requirements. The proposed project aims at overcoming technological challenges to facilitate the translation of wideband lithium niobate acoustic filters for 5G systems. The lithium niobate thin-film resonator technology is already capable of a 5-fold increase in available bandwidth over any other handset filter technology, while keeping filter losses at a minimum in a small form factor. This PFI-TT project will extend the frequency of operation of these filters to those required by 5G standards and overcome the technological challenges to enable this lithium niobate acoustic resonator technology to be deployed at scale by quintuple the bandwidth of the acoustic filters in a radio’s front-end.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
