随着5G移动的应用的推出，预计需要BAW滤波器的频段数量将大幅增长。BAW特别适合于解决低于6 GHz的新无线电频段，也称为nr-1。由于天线系统的复杂性以及由此带来的共存挑战，RF集成是实现LTE + 5G无线完全连接的唯一途径。文章给出了一个概述，并描述了最近的趋势，体声波高频带，宽带滤波器，小型化和热管理。讨论了射频内容的演变和开发复杂射频模块的挑战。
The number of frequency bands requiring BAW filters is expected to grow significantly with the launch of 5G mobile applications. BAW is in particular well suited to address the new radio bands below 6 GHz also referred to as nr-1. RF integration is the only path forward to achieve full connectivity in LTE + 5G wireless due to the complexity of the antenna systems and the resulting coexistence challenges. The article gives an overview and describes recent trends regarding BAW for high frequency bands, wide bandwidth filters, miniaturization and thermal management. Evolution of RF content and the challenges of developing complex RF modules are discussed.
