N Plug (Male) to N Jack (Female) Fixed Attenuator, 4GHz 25W 30dB VSWR 1.35

N Male to N Female Fixed Attenuator | 30 dB | 25 W | Screw-lock | Brass Body

The ROSNOL FA-N1N25A-4G25W30/144-94 is a precision-engineered fixed attenuator designed for RF and microwave systems requiring accurate signal control. This N-type attenuator provides a nominal attenuation of 30 dB with a VSWR of 1.35 across DC to 4 GHz. Rated for 25 watts average power at 25°C, it ensures stable performance in demanding environments. The screw-lock coupling mechanism supports secure connections and over 500 mating cycles.

Constructed from high-quality brass for the body and beryllium copper for the center contact, this attenuator features gold plating over a non-magnetic nickel-phosphorus underlayer for superior conductivity and corrosion resistance. PTFE insulation delivers excellent dielectric properties, complemented by a silicone rubber gasket for robust sealing. Mechanical integrity 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.
