SMA Plug (Male) to Precision N Jack (Female) Adapter, DC-18GHz VSWR 1.15

SMA Plug to Precision N Jack RF Adaptor | Straight Type | Stainless Steel Body*

The ROSNOL AD-A1PCN25B/9XX-9X is a high-performance straight RF adaptor featuring an SMA plug (male) to Precision N jack (female) interface. Engineered for frequencies from DC to 18 GHz, it offers a 50 Ω impedance, VSWR ≤ 1.15 (≥ 23.1 dB), and insertion loss ≤ 0.05 × √F (GHz) dB. The adaptor supports up to 200 W power at 2 GHz and ensures RF leakage suppression ≥ 100 dB up to 1 GHz. It withstands dielectric voltages up to 1000 VRMS and maintains insulation resistance ≥ 5 GΩ. Mechanical reliability is reinforced by screw-lock coupling mechanisms, axial captivation ≥ 28 N, and a minimum of 500 mating cycles. Recommended torque ranges from 0.70 to 1.10 Nm. Operating temperature spans from -5°C to +165°C, with proven resistance to thermal shock, vibration, corrosion, and moisture.

The center contacts on both ends are made of beryllium copper with 3 μinch gold plating over 80 μinch non-magnetic nickel-phosphorus underplating. The adaptor body and coupling nuts are constructed from passivated stainless steel, while the insulators are PTFE. A silicone rubber gasket is included on the SMA side for enhanced sealing performance.

ROSNOL’s precision-engineered RF connectors offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All Rosnol RF components are precision-manufactured in ISO 9001-certified facilities, and are fully RoHS and REACH compliant, ensuring environmental safety and global regulatory alignment. Customization services for plating, materials, and mechanical design are available upon request.
