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. The objective of this research project is to develop RF tunable filters by integrating the micro-electro-mechanical systems (MEMS) technology with high-Q three dimensional resonator structures. The MEMS technology is superior to any other known tuning technology in terms of size, insertion loss and linearity. This research program proposes to introduce a new class of tunable concepts that would allow the realization of tunable filters that can meet the stringent requirements of wireless systems. The industrial partner, Huawei, has divisions in Ottawa and Toronto. It is one the world's largest suppliers of subsystems for wireless base stations. The project will help to train several graduate students and post-doctoral fellows in RF engineering and in the fast emerging field of MEMS technology.

在可重构系统中需要高性能射频可调谐滤波器，以促进有效利用可用频谱。新兴的无线系统被设计成支持多个频带，要求为每个频带使用单独的滤波器。可调谐滤波器的可用性将允许用一个可调谐滤波器替换大量滤波器，该滤波器可以调谐到所需的频带。这将转化为无线基站的显著尺寸和成本的降低。此外，它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。本研究项目的目标是将微机电系统（MEMS）技术与高q三维谐振器结构相结合，开发射频可调谐滤波器。MEMS技术在尺寸、插入损耗和线性度方面优于任何其他已知的调谐技术。本研究计划建议引入一类新的可调谐概念，以实现可调谐滤波器，以满足无线系统的严格要求。其工业合作伙伴华为在渥太华和多伦多设有分支机构。它是世界上最大的无线基站子系统供应商之一。该项目将有助于培养射频工程和快速发展的MEMS技术领域的几名研究生和博士后。
