High Power, Non-Twistable, Flexible
Armored Waveguide

Crush resistant
304 stainless steel flexible armor jacket
Kink resistant
Newer applications for Microwave Systems have required higher frequencies.
This has led to the use of smaller waveguide sizes from WR28 [26.5-40.0GHz] to WR62 [12.4-18.0GHz].
In general, these smaller size waveguide components are more fragile. In particular, high power flexible
waveguide in these sizes are more delicate due to the nature of the design. So when they are subject to
mechanical stress, and/or mishandling, it can result in degraded RF performance or even mechanical failure.
To solve this problem, ATM has developed High Power Flexible Armored Waveguide.
This provides high power flexible waveguide protected from mechanical crushing and kinking.

*Note: Bending Radius is limited by the minium bending radius of the armor.
**Note: Bending Rating Radius for Repeated H-plane is larger than the minium bending
radius of the armor.

The Standard Model Numbers above are the most common parts ordered for size, material and flange.
However, these models can easily be altered to accommodate your custom needs .
When creating a standard model number for your order, please use the desired length (in inches)
of your assembly in place of (L) as shown above.
