Waveguide Flange Standard EIA & IEC

Product Description:​​

Dolph Microwave engineers waveguide flanges to exacting EIA (Electronic Industries Alliance) and IEC (International Electrotechnical Commission) standards, ensuring seamless interoperability in high-power RF/microwave systems. Our flanges support frequency bands from 75 GHz (WR10) to 320 MHz (WR2300+), fabricated from aluminum 6061-T6 for superior conductivity and corrosion resistance. Rigorous testing guarantees VSWR performance ≤1.05:1, minimizing signal loss in critical radar, satellite, and telecom infrastructure. Prototype to production units feature vacuum-rated seals for UHV environments up to 10⁻⁹ Torr.

​​Performance-Driven Characteristics​

​Flanges undergo CNC machining to micron-level tolerances (±0.01mm), enabling reliable contact interfaces from 18 GHz Ka-band to L-band operations. Solutions include MIL-STD-392 compliant RF joints, customizable groove designs for pressurized systems, and specialized variants for half-height/reduced-height waveguides. All designs mitigate multipaction risk at power thresholds exceeding 5 kW continuous wave. Installation kits with alignment pins and EMI gaskets ensure rapid field deployment.
