SMA Plug (Male) to N Jack (Female) 4 Hole Flange Adapter, DC-11GHz VSWR 1.15

SMA Plug (Male) to N Jack (Female) | 4-Hole Flange Panel Adapter | Screw-lock | Brass Body

The ROSNOL AD-A1N25A-PF/H11-H4 is engineered for SMA-to-N panel connections in RF systems requiring durability and precision. Rated for DC to 11 GHz, it offers 50 Ω impedance, VSWR ≤ 1.15, insertion loss ≤ 0.04√f (GHz) dB, and RF leakage ≥ 100 dB up to 1 GHz. Electrical performance includes insulation resistance ≥ 5 GΩ and power handling up to 200 W at 2 GHz. Mechanical features include screw-lock coupling, ≥ 500 mating cycles, and torque range of 0.8–1.1 Nm (SMA) and 0.7–1.1 Nm (N).

The SMA contact is phosphor bronze with gold plating, while the N contact uses brass, both plated over nickel-phosphorus underplating for optimal conductivity. SMA body and coupling nut are brass with gold plating, while N body and fastening hardware use brass with copper-tin-zinc alloy finish. PTFE insulators provide superior dielectric properties, and silicone rubber gaskets ensure environmental sealing for reliable operation.

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.
