Description
EIA 3 1/8" Flange to N Plug (Male) Adapter | Straight | Brass Body
The ROSNOL AD-EIA318N15A/G3-G33 is a precision EIA adapter that combines an EIA 3-1/8" flange with an N-type male plug for RF signal continuity from DC to 3 GHz. It provides 50 Ω impedance, VSWR ≤ 1.07 (≥29.4 dB return loss), and dielectric withstanding voltage up to 6000 V RMS. Both sides support ≥500 mating cycles, delivering robust performance for high-power applications.Centre contacts are phosphor bronze with silver plating, while bodies are brass with nickel plating. PTFE insulators guarantee dielectric stability, and silicone rubber gaskets enhance environmental protection. Coupling nuts are brass with nickel plating for secure engagement.
ROSNOL’s precision-engineered RF adapters deliver reliable performance across a wide range of RF and microwave systems. Designed to meet the stringent demands of high-frequency signal transmission, ROSNOL adapters offer a cost-effective alternative to products from leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring global environmental and safety standards. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
