Custom Switched Filter Banks

API Technologies' Switched Filter Bank designs draw from a multi-disciplined staff with many years of experience in both microwave filters and control components. By combining filter and switch design expertise, API can provide integrated switched filter assemblies that not only reduce the overall mechanical footprint, but also offer improved electrical performance. This improved performance is achieved by having the ability to align the filters to the switches, thus removing any of the associated mismatches between the two. The end product is an integrated assembly with:

  • Improved VSWR
  • Less passband variation
  • Lower insertion loss
  • Reduced component count
  • Improved RF Shielding/Isolation
  • Higher reliability

Product Development
  • All SFB designs are based on simulations using tools such as HFSS, Sonet, Microwave Office and Genesys and State-of-the-art 3D SolidWorks modeling.
  • These sophisticated models are used to ensure the best electrical performance, while maintaining a compact, low weight product in the shortest possible lead-time.
