摘要

多频段/多系统移动电话需要复杂的射频前端架构。复杂性已经增加到为额外的频带增加开关和整个信号分支不再具有成本效益的程度。其他概念包括“聚合”功率放大器和支持它们的开关概念。滤波器和双工器在融合架构中发挥着关键作用，我们将对它们的需求进行回顾。将指出为不同无线标准组合滤波器功能所带来的挑战。现有的射频滤波器技术是基于表面声波(SAW)或体声波(BAW)技术中实现的高q声波谐振器，并且不允许动态改变频率特性。可调谐射频滤波器的概念——追求“圣杯”——将被讨论，并概述这一问题的现状。

Filter technologies for converged RF-frontend architectures: SAW, BAW and beyond

Multi-band/multi-system mobile phones require a complex RF-frontend architecture. Complexity has increased to a point where adding switches and whole signal branches for an additional band is no longer cost effective. Alternative concepts involve ‘converged’ power amplifiers and switching concepts supporting those. Filters and duplexers play a key role in converged architectures and their requirements will be reviewed. Challenges that arise from combining filter functions for different wireless standards will be pointed out. Existing RF-filter technologies are based on high-Q acoustic resonators realized either in Surface Acoustic Wave (SAW) or Bulk-Acoustic-Wave (BAW) technology and do not allow changing the frequency characteristics on the fly. Concepts for tunable RF-filters - pursuing the ‘holy grail’ - will be discussed and an overview on the status of this matter will be presented.
