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

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

The ROSNOL AD-A1N25A/H11-H3 is a precision SMA-to-N straight adapter engineered for high-frequency performance up to 12 GHz. It offers 50 Ω impedance, VSWR ≤ 1.15 (≥ 23.13 dB return loss), and insertion loss ≤ 0.05√f (GHz) dB. Electrical integrity includes insulation resistance ≥ 5 GΩ, RF leakage ≥ 100 dB up to 1 GHz, and power handling up to 200 W at 2 GHz. Mechanical features include 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 and body are phosphor bronze and brass with 3 μinch gold plating over 80 μinch nickel-phosphorus underplating, while the N contact uses phosphor bronze with gold plating and a brass body finished in nickel. PTFE insulators ensure dielectric stability, and silicone rubber gaskets provide 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.
