SMA Plug (Male) to N Jack (Female) Adapter, DC-12GHz VSWR 1.15

SMA Plug (Male) to N Jack (Female) | Straight Adapter | Screw-lock | Stainless Steel Body

The ROSNOL AD-A1N25A/9XX-9X is a precision RF adapter designed to connect SMA Plug (Male) and N Jack (Female) interfaces in 50 Ω systems. Operating from DC to 12 GHz, it features VSWR ≤ 1.15, insertion loss ≤ 0.04 × √F (GHz) dB, 480 V rms working voltage, and power handling up to 200 W at 2 GHz. Both interfaces utilize screw-on coupling mechanisms with a minimum of 500 mating cycles for reliable long-term performance.

Both SMA and N center contacts are manufactured from beryllium copper with gold plating over a non-magnetic nickel-phosphorus underplating. Beryllium copper provides outstanding conductivity, spring properties, and mechanical durability. The body and coupling nut are constructed from stainless steel with passivated surfaces. Stainless steel offers superior corrosion resistance, high mechanical strength, and long service life, while passivation enhances environmental durability. PTFE insulators provide excellent dielectric stability and low RF loss.

ROSNOL’s precision-engineered RF adapters deliver reliable performance across a wide range of RF and microwave systems. Designed to meet the stringent demands of high-frequency signal transmission, ROSNOL adapters offer a cost-effective alternative to products from leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring global environmental and safety standards. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
