High performance radio frequency (RF) tunable filters are needed in reconfigurable systems to facilitate efficient utilization of the available frequency spectrum. Emerging wireless systems are designed to support several frequency bands, requiring the use of an individual filter for each frequency band. The availability of tunable filters will allow the replacement of a large number of filters by just one tunable filter which can be tuned to desired frequency band. This will translate to significant size and cost reduction of wireless base stations. In addition, it will allow operators to manage dynamically the hardware resources to accommodate multi-standards requirements and network traffic.

在可重构系统中需要高性能的射频(RF)可调谐滤波器来促进可用频谱的有效利用。新兴的无线系统被设计为支持多个频段，需要为每个频段使用单独的滤波器。可调谐滤光器的可用性将允许仅用一个可调谐到所需频带的可调谐滤光器来替换大量的滤光器。这将转化为无线基站的显著尺寸和成本降低。此外，它还将允许运营商动态管理硬件资源，以适应多标准要求和网络流量。
