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

The ROSNOL FA-N1N25A-6G500W40/133-H3 is a precision high-power attenuator engineered for RF systems requiring substantial signal attenuation. This N-type attenuator provides a nominal attenuation of 40 dB with an attenuation deviation of −1.2/+1.5 dB across DC to 6 GHz. Rated for 500 watts average power at 25°C, it supports stable operation with VSWR ≤ 1.35 (Return Loss ≥ 16.54 dB). The screw-lock coupling ensures secure and repeatable mating.

The attenuator body is constructed from nickel-plated brass and features gold-plated phosphor bronze and brass center contacts for reliable conductivity. PTFE insulation and a silicone rubber gasket provide excellent dielectric and environmental performance. An integrated aluminum heatsink with black anodized finish supports effective thermal management. Mechanical integrity includes ≥500 mating cycles, coupling nut retention ≥450 N, axial captivation ≥28 N, and coupling test torque up to 1.70 Nm (recommended 0.7–1.1 Nm). Operating temperature range extends from −55°C to +125°C.

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-power 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 comply with RoHS and REACH regulations, ensuring global environmental and safety standards.
