Description
SMA Plug (Male) to BNC Jack (Female) Adapter | Screw-lock & Bayonet-lock | Copper-Tin-Zinc Alloy Body
The ROSNOL AD-A1B25A/H44-H4 is a high-performance RF adapter supporting DC to 6 GHz. It delivers 50 Ω impedance, VSWR ≤1.2 (≥20.83 dB), and insertion loss ≤0.05 × √F (GHz) dB. Mechanical features include screw-lock coupling on the SMA side and bayonet-lock on the BNC side, ≥500 mating cycles, axial captivation ≥27 N, and torque range of 0.8–1.1 Nm.This adapter is built with a copper-tin-zinc alloy body and coupling nut, phosphor bronze center contacts with 3 µinch gold plating over non-magnetic nickel-phosphorus underplating, and PTFE insulators for stable dielectric performance.
ROSNOL’s precision-engineered solutions offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All ROSNOL components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring environmental safety and global regulatory alignment. Customization services for materials, plating, and mechanical design are available to support specialized requirements across a wide range of RF and microwave applications.
