Tunable High Quality Factor Radio Frequency Filters

Next generation DoD electronic warfare (EW) and commercial communication systems are currently faced with the challenge of delivering a receiver capable of multi-band reception. The receiver must meet various wireless standards and cover an expanse of frequencies and bandwidths. Traditionally the solution to the multi-band converge problem employed many off chip frequency fixed filters and an individually tuned receiver chain for each band. This approach provides band selection and out-of-band jammer reduction with the cost of an increasingly unwieldy system. As the number of communication bands increase, the traditional approach results in a greater number of filters and, correspondingly, a higher cost, greater complexity, and heavier weight making this approach to multi-band receivers impractical. MaXentric will target a fully integrated design with a frequency agile front end filter capable of providing band selection and meeting typical wireless standards (WiFi, GPS, Bluetooth, TV, MUOS, cellular, etc.). A full receiver design will be implemented with each stage of the receiver optimized for broad-band, high dynamic range reception.
