Description
EIA 3-1/8" Flange to N Jack (Female) Adapter | Straight | Brass Body
The ROSNOL AD-EIA318N25A/G3-G3 is a precision EIA adapter that features an EIA 3-1/8" flange and an N-type female jack for efficient RF signal routing from DC to 3 GHz. It maintains 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 for dependable performance in high-frequency systems.Centre contacts are phosphor bronze with silver plating, while bodies are brass with nickel plating. PTFE insulators provide excellent dielectric properties, and silicone rubber gaskets ensure environmental sealing. Coupling nuts are brass with nickel plating for secure connections.
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.
