SMA Plug (Male) to Precision N Jack (Female) Adapter, DC-18GHz VSWR 1.15

SMA Plug (Male) to Precision N Jack (Female) | Straight Adapter | Screw-lock | Brass Body

The ROSNOL AD-A1PCN25A/111-13 adapter provides stable RF connectivity with 50 Ω impedance and DC–18 GHz frequency range. It achieves VSWR ≤ 1.15, insertion loss ≤ 0.05 × √F (GHz) dB, and insulation resistance ≥ 5 GΩ. Contact resistance is ≤ 3 mΩ (SMA) and ≤ 1 mΩ (N), with outer contact resistance ≤ 2 mΩ and ≤ 0.25 mΩ respectively. Rated for 1000 V rms test voltage and 480 V rms working voltage, it handles up to 200 W at 2 GHz with RF leakage ≥ 100 dB up to 1 GHz. Mechanical features include screw-lock coupling, axial captivation ≥ 28 N, torque range 0.80–1.10 Nm (SMA) and 0.70–1.10 Nm (N), and minimum 500 mating cycles.

The adapter uses brass bodies with nickel plating for Precision N and gold-plated brass for SMA, ensuring excellent conductivity and corrosion resistance. Center contacts are brass with gold plating over nickel underplating, while insulators are PTFE (SMA) and PS (N). Coupling nut is brass with gold plating, and a silicone rubber gasket provides environmental sealing. Overall length is 43.8 mm [1.724 in], hex size 8 mm [.315 in], and thread 5/8-24 UNEF-2A.
