N Plug (Male) to N Jack (Female) Fixed Attenuator, 5GHz 500W 40dB VSWR 1.35

N Male to N Female Fixed Attenuator | 40 dB | 500 W | Screw-lock | Brass Body

The ROSNOL FA-N1N25A-5G500W40/944-94 is a robust fixed attenuator engineered for high-power RF and microwave systems. This N-type attenuator delivers a nominal attenuation of 40 dB with an attenuation deviation of -1.2/+1.5 dB, ensuring precise signal control across DC to 5 GHz. Rated for 500 watts average power at 25°C, it maintains VSWR ≤1.35 for dependable return loss performance. The screw-lock coupling mechanism provides secure connections and supports over 500 mating cycles.

The body is made of 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 excellent dielectric properties, and a silicone rubber gasket enhances sealing reliability. This model includes aluminum heatsinks with black anodized finish for superior thermal management. Mechanical specifications include coupling nut retention ≥450 N and axial captivation ≥28 N.
