Description
SMA Plug (Male) to 3.5mm Jack (Female) Adapter | Screw-lock | Stainless Steel Body
The ROSNOL AD-A1PC25A/9XX-9X adapter ensures high-precision RF connectivity with 50 Ω impedance and a frequency range from DC to 18 GHz. It offers VSWR ≤1.2 (≥20.8 dB return loss) and insertion loss ≤0.05√F (GHz) dB, delivering excellent signal integrity. Mechanical design includes screw-lock coupling on both ends, supporting ≥500 mating cycles. Axial contact captivation is ≥27 N, with recommended torque of 0.9 Nm for SMA and 0.80–1.10 Nm for 3.5mm. Dimensions: overall length 20.3 mm [.799 in], hex sizes SW8 [.315 in] and SW7 [.276 in].Engineered with premium materials, center contacts are beryllium copper with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating for optimal conductivity. Bodies are stainless steel passivated, insulators are PTFE (SMA) and PS (3.5mm), and coupling nuts are stainless steel passivated. Gasket is silicone rubber for enhanced 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.
