Description
75 Ohm BNC–F Straight RF Adapter | DC–3 GHz | Bayonet‑Lock to Screw‑Lock Interface
ROSNOL AD-B2F27A/H4-H4 is a 75-ohm BNC Jack (Female) to 75-ohm F Jack (Female) straight adapter supporting DC to 3 GHz operation with a maximum VSWR of 1.30. The adapter ensures stable connectivity through a bayonet-lock mechanism on the BNC side and a screw-lock interface on the F side, each rated for at least 500 mating cycles. With center-contact captivation of 15 N on the BNC end and 20 N on the F end, the adapter maintains consistent electrical performance across low-loss RF transmission paths.
The center contacts on both sides are constructed from phosphor bronze with gold plating over a non-magnetic nickel-phosphorus underlayer. The brass bodies use a copper-tin-zinc alloy for structural rigidity, while PTFE insulators maintain dielectric stability. This adapter provides reliable interconnection between BNC and F-type interfaces commonly found in broadband distribution, test platforms, and communication modules.
ROSNOL adapters are manufactured under ISO 9001-certified processes and comply fully with RoHS and REACH requirements. The series offers high performance and long-term reliability at competitive pricing, serving as a strong alternative to high-cost international brands, with customization options for materials, plating, and mechanical design.
