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-A1PCN25B/933-93 adapter ensures dependable RF performance 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), outer contact resistance ≤ 2 mΩ and ≤ 0.25 mΩ respectively. Rated for 1000 V rms test voltage and 480 V rms working voltage, it supports power handling up to 200 W at 2 GHz with RF leakage ≥ 100 dB up to 1 GHz. Mechanical integrity includes 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.

Both SMA and Precision N bodies are brass with nickel plating for corrosion resistance. Center contacts are beryllium copper with 3 μinch gold plating over 80 μinch non-magnetic nickel-phosphorus underplating. Insulators are PTFE for both ends, complemented by a silicone rubber gasket for environmental sealing. Dimensions include overall length 31.12 mm [1.225 in], hex sizes 8 mm [.315 in] and 14 mm [.551 in], and thread 5/8-24 UNEF-2A.
