Description
SMA Plug (Male) to Precision N Plug (Male) Adapter | Screw-lock | Brass & Stainless Steel Body
The ROSNOL AD-A1PCN15A/911-9XX adapter provides high-precision RF connectivity with 50 Ω impedance and DC to 18 GHz frequency range. It offers VSWR ≤1.15 (≥23.1 dB return loss) and insertion loss ≤0.05√F (GHz) dB for excellent signal integrity. Mechanical design includes 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: overall length 42.88 mm [1.688 in], hex sizes SW8 [.315 in], SW11 [.433 in], SW13 [.512 in], SW19 [.748 in].Engineered with premium materials, SMA center contacts are beryllium copper, body and coupling nut are brass with gold plating, while Precision N uses stainless steel passivated. All contacts feature 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating. Insulators are PTFE (SMA) and PS (Precision N), with silicone rubber gaskets for durability.
ROSNOL’s precision-engineered RF adapters deliver reliable performance across diverse RF and microwave systems. Designed to meet stringent high-frequency requirements, ROSNOL adapters offer a cost-effective alternative to leading global brands. All components are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH standards. Customization for materials, plating, and mechanical design is available to support specialized interconnect needs.
