7/16 Plug (Male) to EIA 1 5/8

7/16 Plug (Male) to EIA 1-5/8" Flange Adapter | Screw-lock | Brass Body

The ROSNOL AD-D1EIA1585A/G33-G3 is a precision EIA flange adapter that combines a 7/16 male plug with an EIA 1-5/8" flange for high-power RF connections from DC to 3 GHz. It offers 50 Ω impedance, VSWR ≤ 1.07 (≥29.42 dB return loss), and supports dielectric withstanding voltage up to 6000 V RMS. Average power handling reaches 3.4 kW at 900 MHz, with peak power up to 90 kW. The screw-lock coupling ensures secure engagement and durability with ≥500 mating cycles on the 7/16 side and ≥100 cycles on the EIA side.

Centre contacts are phosphor bronze with silver plating for superior conductivity, while bodies and coupling nuts are brass with nickel plating. The insulator is PTFE, and silicone rubber gaskets provide environmental sealing. The EIA flange includes stainless steel hardware for robust installation.

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.
