Description
SMA Plug (Male) to N Jack (Female) | Straight Adapter | Screw-lock | Brass Body
The ROSNOL AD-A1N25A/H33-H3 is designed for high-frequency SMA-to-N interconnects, supporting DC to 12 GHz with 50 Ω impedance, VSWR ≤ 1.15, and insertion loss ≤ 0.05√f (GHz) dB. It ensures RF leakage ≥ 100 dB up to 1 GHz and power handling up to 200 W at 2 GHz. Mechanical reliability includes screw-lock coupling, ≥ 500 mating cycles, and torque ranges of 0.80–1.10 Nm (SMA) and 0.70–1.10 Nm (N).Both SMA and N contacts are phosphor bronze with gold plating over nickel-phosphorus underplating. Bodies and coupling nuts are brass with nickel finish, while PTFE insulators provide excellent dielectric properties. Silicone rubber gaskets enhance environmental sealing for long-term durability.
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.
