Custom Switched Filter Banks

Spectrum Control's switched filter bank IMAs draw on the expertise of our multi-disciplined staff with many years of experience in both microwave filters and control components. By combining filter and switch design expertise, Spectrum Control can provide integrated switched filter assemblies that not only reduce the overall mechanical footprint, but also offer improved electrical performance. 

The result is an integrated assembly with:

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

The Spectrum Control IMA Difference

Vertically integrated design and manufacturing

Applying our extensive experience and in-house component technology we maintain tight control over critical performance parameters for exceptional performance.

Design Choices - Standard, Semi-Custom, Custom
  • Standard Designs: By choosing a product from our database of existing designs, the time and cost to engineer a new product can be eliminated. 
  • Semi-Standard Designs: We commonly modify existing designs to minimize the development cost and cycle time. The frequency band breaks, number of channels or drive circuity of many switched filter banks can be readily optimized to suit other applications.
  • Custom Designs: Spectrum Control excels in developing custom solutions to satisfy challenging requirements.
Simulation and Modeling

All 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.
