Description
N Jack (Female) to EIA 7/8" Flange Adapter | Screw-lock | Brass Body
The ROSNOL AD-N2EIA785A/G3-G3 is a precision EIA adapter that features an N-type female jack and an EIA 7/8" flange for dependable RF signal transmission from DC to 5 GHz. It maintains 50 Ω impedance, VSWR ≤ 1.10 (≥26.44 dB return loss), and dielectric withstanding voltage up to 4000 V RMS. Average power handling is 2.3 kW at 900 MHz, with peak power up to 90 kW. The screw-lock coupling mechanism ensures robust connections and supports ≥500 mating cycles on the N side and ≥100 cycles on the EIA side.Centre contacts are phosphor bronze with silver plating, while bodies and flange nuts are brass with nickel plating. PTFE insulators guarantee dielectric stability, and silicone rubber gaskets enhance environmental protection. Stainless steel hardware is included for secure flange mounting.
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.
