BSC – Agile Filters



Agile & Tuneable Solutions

BSC recognise that future RF systems must be flexible and adaptive to changes in spectrum and configuration, both in use and throughout their life cycle. As part of our adaptive filtering roadmap, BSC are introducing novel approaches to market, which surpass the industry standards in terms of selectivity, power handling, miniaturisation and flexibility.

High-Power Mil-Comms

BSC has developed and brought to production a 225 MHz – 400 MHz electronically-tuneable filter for Mil-Comms applications, offering a highly-selective 4-pole cross-coupled response, 50 W hot-tuned power handling and FPGA-based control with user-reconfigurability.

Agile Radar & EW Front-end

The Mil-Comms solution is built upon a flexible control architecture, which may be combined with alternative tuning mechanisms at S-Band, X-Band and beyond. The result is a family of tuneable solutions, configured to suit agile Radar or Broadband EW front-end applications.

Miniaturised & Phased-Array

Building on BSC’s Thin Film filtering & integration heritage, it is possible to create highly-miniaturised tuneable filters which offer a level of performance that is traditionally commensurate with larger technologies. Such reduction in size allows for direct integration of agility into array elements themselves, opening up scope for greater function and resilience at system level.
