Description
SMA Plug (Male) to Precision N Plug (Male) Adapter | Screw-lock | Brass Body
The ROSNOL AD-A1PCN15B/911-933 adapter provides high-performance RF connectivity with 50 Ω impedance and a frequency range from DC to 18 GHz. It achieves VSWR ≤1.15 (≥23.1 dB return loss) and insertion loss ≤0.05√F (GHz) dB, ensuring minimal signal loss. Mechanical design features screw-lock coupling on both SMA and Precision N sides, supporting ≥500 mating cycles. Axial contact captivation is ≥28 N, with recommended torque of 0.80–1.10 Nm for SMA and 0.70–1.10 Nm for Precision N. Dimensions: overall length 33.88 mm [1.334 in], hex sizes SW8 [.315 in], SW14 [.551 in], SW19 [.748 in].Constructed from premium materials, SMA center contacts are beryllium copper with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating, while body and coupling nut are brass with gold plating. Precision N body and coupling nut are brass with nickel finish. Insulators are PTFE, and SMA side includes a silicone rubber gasket for enhanced sealing.
