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.
