SMA Jack (Female) to N Jack (Female) Adapter | 4‑Hole Flange Mount | Brass Body
The ROSNOL AD-A2N25A-PF/99-94 is a precision SMA jack (female) to N jack (female) 4‑hole flange‑mount adapter designed for broadband RF applications from DC to 11 GHz. With 50 Ω impedance, VSWR ≤ 1.15, insertion loss ≤ 0.04 × √F(GHz), and RF leakage ≥ 100 dB up to 1 GHz, it ensures stable, low‑loss interface transition between SMA and N‑type connectors. Mechanical reliability is enhanced by screw‑lock coupling on both sides, ≥ 500 mating cycles, and coupling‑nut retention ≥ 270 N (SMA) and ≥ 450 N (N‑type).
This adapter uses beryllium‑copper centre contacts with gold plating over a non‑magnetic nickel–phosphorus underlayer to ensure excellent conductivity and corrosion resistance. The N‑type body employs a copper–tin–zinc alloy for structural strength, while the SMA section incorporates gold‑plated beryllium‑copper construction. PTFE insulation ensures stable dielectric properties across the full temperature and frequency range. Suitable for telecommunications networks, radar systems, laboratory analyzers, and mixed‑standard RF platforms requiring robust SMA–N interface conversion.
ROSNOL RF adapters are manufactured in ISO 9001‑certified facilities and fully comply with RoHS and REACH standards. Offering high quality at competitive pricing, they function as reliable alternatives to leading European and American brands. Comprehensive customization services are available for specialized mechanical, material, and plating requirements.
