Adapters/Transitions Tapered Waveguide to Waveguide
Our Tapered Waveguide Transitions are a means of propagating RF energy from one waveguide size to another. Standard Transitions are available in 2 Lengths:

  • The Longer transitions are for better VSWR (1.05:1 Typ.)
  • The Shorter transitions (VSWR 1.08:1 Typ.) are for minimum length.

Brass Transitions are Silver Plated per QQ-S-365D class A. Aluminum Transitions are Chem-filmed per MIL-C-5541E. Transitions are finished with PENN ENGINEERING'S Polyurethane Blue Paint. We can customize plating or painting to suit your application on request.

Custom Transitions are available upon request.
