Description
N Fixed Attenuator | Plug (Male) to Jack (Female) | 50 dB | 500 W Power Handling | Screw-Lock | Stainless Steel Body
The ROSNOL FA-N1N25A-6G500W50/9XX-9X fixed attenuator covers DC to 6 GHz with 50 Ω impedance and VSWR ≤ 1.4. It delivers 50 dB nominal attenuation with ±1 dB accuracy and supports average power handling of 500 W (at 25 °C). The screw-lock coupling ensures secure engagement, contact captivation (axial) ≥ 28 N, ≥ 500 mating cycles, and recommended coupling torque of 0.7–1.1 Nm (test torque ≤ 1.7 Nm). Insertion loss corresponds to the specified attenuation. Insulation resistance and voltage ratings follow ROSNOL’s high-reliability design standards. Accuracy of attenuation & power is verified across the specified band.Materials and plating are identical to the 40 dB variant: gold-plated beryllium copper center contact over non-magnetic nickel–phosphorus underplating (3 microinch Au over 80 microinch Ni–P); passivated stainless steel body and coupling nut; PTFE insulator; silicone rubber gasket. The design provides strong corrosion resistance and thermal stability across −65 °C to +165 °C.
ROSNOL’s precision-engineered RF attenuators deliver reliable performance and excellent value as alternatives to leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH. Customization of materials, plating, attenuation values, and mechanical details is available to meet specialized requirements.
