Description
SMA Plug (Male) to N Jack (Female) | Straight Adapter | Screw-lock | Brass Body
The ROSNOL AD-A1N25A/944-H4 is engineered for high-frequency SMA-to-N connections, 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 integrity includes screw-lock coupling, ≥ 500 mating cycles, and torque ranges of 0.80–1.10 Nm (SMA) and 0.70–1.10 Nm (N).The SMA contact is beryllium copper, while the N contact uses phosphor bronze, both plated with 3 μinch gold over 80 μinch nickel-phosphorus underplating. Bodies and coupling nuts are brass with copper-tin-zinc alloy finish, and PTFE insulators provide superior dielectric stability. Silicone rubber gaskets ensure environmental sealing.
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.
