N Plug (Male) to N Jack (Female) Fixed Attenuator, 4GHz 25W 10dB VSWR 1.35

N Male to N Female Fixed Attenuator | 10 dB | 10 W | Screw-lock | Brass Body

The ROSNOL FA-N1N25A-4G10W10/144-94 is a high-precision fixed attenuator engineered for RF and microwave applications. This N-type attenuator delivers a nominal attenuation of 10 dB with a VSWR of 1.2 across DC to 4 GHz. Rated for 10 watts average power at 25°C, it ensures consistent signal performance in critical environments. The screw-lock coupling mechanism guarantees secure connections and durability with over 500 mating cycles.

The body is crafted from brass with a copper-tin-zinc alloy finish, while the center contact uses beryllium copper with gold plating over a nickel-phosphorus underlayer for optimal conductivity and corrosion resistance. PTFE insulation provides excellent dielectric properties, and a silicone rubber gasket ensures environmental sealing. Mechanical strength includes coupling nut retention ≥450 N and axial captivation ≥28 N.

ROSNOL’s precision-engineered RF attenuators deliver reliable performance across a wide range of RF and microwave systems. Designed to meet the stringent demands of high-frequency signal transmission, ROSNOL attenuators 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.
