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/H31-H3 is a high-quality SMA-to-N panel adapter designed for RF and microwave applications requiring secure flange mounting. It supports DC to 11 GHz with 50 Ω impedance, VSWR ≤ 1.15, insertion loss ≤ 0.04√f (GHz) dB, and RF leakage ≥ 100 dB up to 1 GHz. Electrical specifications include insulation resistance ≥ 5 GΩ and power handling up to 200 W at 2 GHz. Mechanical integrity is ensured with screw-lock coupling, ≥ 500 mating cycles, and torque range of 0.9 Nm (SMA) and 1.36 Nm (N).

The SMA and N contacts are phosphor bronze with gold plating over nickel-phosphorus underplating. SMA body and coupling nut are brass with gold plating, while N body uses brass with nickel 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.
