N Plug (Male) to N Jack (Female) Fixed Attenuator, 4GHz 25W 40dB VSWR 1.35

N Male to N Female Fixed Attenuator | 40 dB | 25 W | Screw-lock | Brass Body

The ROSNOL FA-N1N25A-4G25W40/144-94 is a high-precision fixed attenuator engineered for RF and microwave applications requiring significant signal reduction. This N-type attenuator delivers a nominal attenuation of 40 dB with VSWR ≤1.25 across DC to 4 GHz, ensuring excellent return loss performance. Rated for 25 watts average power at 25°C, it guarantees consistent signal integrity under rigorous conditions. The screw-lock coupling mechanism provides secure connections and supports 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 for optimal conductivity and corrosion resistance. PTFE insulation ensures superior dielectric properties, and a silicone rubber gasket enhances environmental sealing. This model also includes aluminum heatsinks with black anodized finish for improved thermal management. 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.
