Description
N Female to N Female Fixed Attenuator | 40 dB | 500 W | Screw-lock | Stainless Steel Body
The ROSNOL FA-N2N25A-6G500W40/9X-9X is a high-power fixed attenuator engineered for demanding RF applications up to DC to 6 GHz. This N-type attenuator provides a nominal attenuation of 40 dB with an attenuation deviation of −1.2/+1.5 dB, enabling controlled signal reduction under high power conditions. Rated for 500 watts average power at 25°C, it maintains VSWR ≤ 1.35 (Return Loss ≥ 16.5 dB) for stable impedance matching. The screw-lock coupling mechanism ensures secure installation and consistent electrical performance.Constructed with a passivated stainless steel body, the attenuator incorporates beryllium copper center contacts with gold plating over non-magnetic nickel-phosphorus underplating to achieve low contact resistance and long-term durability. PTFE insulation and a silicone rubber gasket provide excellent dielectric performance and environmental sealing. Mechanical specifications include mating cycles ≥ 500, axial captivation ≥ 28 N, coupling test torque ≤ 1.7 Nm (recommended 0.7–1.1 Nm), and an operating temperature range from −65°C to +165°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-efficient 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. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
