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

Comparison of BSC response (solid line) to existing products (dotted)

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

Agile Radar & EW Front-end

Block Diagram

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.

Active filters

BSC present an X band QFN packaged tunable regenerative filter. This tunable filter includes amplification that recovers loss within the passband of the filter, but without amplifying signals outside of the filter passband.

Measured data is shown indicating that almost 0dB loss can be provided with the passband  whilst maintaining an excellent roll off and wide stopbands outside the frequencies of interest.

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 in L, S and X bands 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.
