Innovative Waveguide and 3D Tunable Filters

High performance tunable filters are needed in wireless communication systems to facilitate efficient utilization of the available frequency spectrum. They can be employed to replace large filter banks in advanced systems concepts that self-adapt to environmental requirements. In addition, tunable filters can be used to consolidate more hardware into fewer units, which in turn will reduce size and cost. The presentation addresses recent developments in three-dimensional high-Q multi-function filters. The talk also discusses techniques for maintaining filter performance over a wide tuning range.
