N Jack (Female) to BNC Jack (Female) 4-Hole Panel Adapter, DC-4GHz VSWR 1.2

N Jack (Female) to BNC Jack (Female) | 4-Hole Panel Adapter | Screw-Lock & Bayonet-Lock | Brass Body

The ROSNOL AD-N2B25A-PF/94-94 is a 4-hole panel RF adapter designed for secure connectivity between N jack female and BNC jack female interfaces. It operates from DC to 4 GHz with 50-ohm impedance, VSWR ≤ 1.20, and insertion loss ≤ 0.1√F (GHz) dB. Electrical performance includes insulation resistance ≥ 5 GΩ, working voltage 400 V rms, and power handling up to 80 W at 2 GHz. The adapter features screw-lock coupling on the N side and bayonet-lock on the BNC side, axial captivation ≥ 28 N, and supports at least 500 mating cycles.

Material construction ensures durability and signal integrity. Both center contacts are beryllium copper with gold plating 3 microinch over a non-magnetic nickel-phosphorus underplating 80 microinch; bodies are brass with copper-tin-zinc alloy finish, and insulators are PTFE. This design provides excellent corrosion resistance and stable RF performance across temperature variations.

ROSNOL’s precision-engineered RF adapters deliver high quality and dependable performance at competitive pricing, making them an ideal alternative to leading European and American brands. All ROSNOL components are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH regulations. Customization services for materials, plating, and mechanical design are available to meet specialized interconnect requirements.
