SMA Plug (Male) to Precision N Plug (Male) 4 Hole Flange Adapter, DC-18GHz VSWR 1.20

SMA Plug (Male) to Precision N Plug (Male) 4-Hole Flange Adapter | Screw-lock | Brass Body

The ROSNOL AD-A1PCN15A-PF/H11-H44 adapter provides high-performance RF connectivity with 50 Ω impedance and a frequency range from DC to 18 GHz. It offers VSWR ≤1.2 (≥20.83 dB return loss) and insertion loss ≤0.04√F (GHz) dB for superior signal integrity. Mechanical design includes a 4-hole flange mount with screw-lock coupling on both ends, 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: flange size 25.4 mm [1.000 in], hole diameter 3.2 mm [.126 in], overall length 33.9 mm [1.334 in].

Engineered with high-quality materials, SMA center contacts are phosphor bronze 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 copper-tin-zinc alloy finish. Insulators are PTFE, and gaskets are silicone rubber for durability.
