Waveguide Flange Engineering Guide

Essential Interface Standards for High-Frequency Transmission

Interface & Connection

A waveguide flange is the critical connection interface. To ensure minimal losses when connecting two sections, the flange types must match perfectly.

  • Available in Square or Circular shapes.
  • Bolted together with 4 or more bolts for maximum stability.

Flange Categories

UBR (Cover / Plain Flange): Features a flat face. Most FT-RF products utilize this design for optimal matching performance.

PBR (O-Ring Flange): Designed with an 'O' ring groove for superior environmental or pressure sealing.

MANUFACTURING STANDARD

Global Compatibility & Compliance

To ensure consistency across international manufacturers, there are two primary standard bodies for rectangular waveguide flanges:

  • 🔹 North American EIA: Electronic Industries Alliance Shapes
  • 🔹 International IEC: International Electrotechnical Commission Shapes

FT-RF Engineering Note: All our antennas are designed and manufactured in strict accordance with IEC standards to guarantee worldwide interoperability and precision.
