Electrical and Mechanical Details
TE11 model range
The listed C-series covers TE11 operating bands from 3.89 to 116 GHz. Circular waveguide bandwidth is narrower than comparable rectangular waveguide, so select by the full required band.
TE01 low-loss behavior
For TE01 transmission, the product data states that conductor loss decreases as frequency rises and cites loss below 0.05 dB/m in critical bands.
Dual-polarization support
Circular geometry supports orthogonally polarized waves for dual-polarization feed and polarization-sensitive assemblies.
GB, EIA and 153-IEC cross-reference
Each listed model includes GB, EIA and 153-IEC circular-waveguide designations for interface reference.

Where Circular Tubing Is Used
Radar rotary joints
Straight circular sections for rotating microwave interfaces, including airborne and scanning radar assemblies.
Satellite communication feeders
Circular sections for feed chains where the required diameter, band and polarization arrangement are defined by the system.
Resonant cavities
Cut-to-length tube sections for cavity geometry controlled by the mechanical and RF design.
Polarization-sensitive RF assemblies
Circular geometry for orthogonal-polarization paths, polarization attenuators and related telecom or feeder assemblies.
5G backhaul system hardware
Use when the specified RF path calls for a circular waveguide section within the listed frequency and dimensional range.
Send the Information Needed to Quote the Correct Tube
Operating band
Minimum and maximum frequency, not only the center frequency.
Tube size
C-series, GB/EIA/153-IEC designation or required internal diameter.
Finished length
Required cut length within the listed 50 to 3000 mm range.
Material
Standard Al model or requested Aluminum, OFHC, Copper, Brass, or another required alloy.
Mating and drawing data
PDF, STEP, sketch, mating-part dimensions or existing part number when the tube interfaces with other hardware.
Quantity and verification
Quantity plus any dimensional records, inspection items or RF test records required with the order.
Match the Tube to the Rest of the RF Path
Rigid tube does not fit the route
Use Seamless Flexible WG when the transmission path needs a flexible alignment or routing section instead of a straight rigid tube.
Flexible Waveguide Selection Guide
The assembly needs a defined mating flange
Review Waveguide Flange Standard EIA & IEC references before the mating interface is released.
Waveguide Flange Size Guide
The circular tube must connect to rectangular waveguide
Use a Rectangular To Circular Waveguide Transition when the RF chain changes between rectangular and circular interfaces.
