Description
N Male to N Female Fixed Attenuator | 6 dB | 100 W | Screw-lock | Brass Body
The ROSNOL FA-N1N25A-6G100W3/133-H3 is a high-precision fixed attenuator for applications requiring moderate attenuation with high power capability. This N-type attenuator delivers 6 dB nominal attenuation with an attenuation deviation of ±0.80 dB, maintaining consistent attenuation accuracy from DC to 6 GHz. It is rated for 100 W average power at 25°C (linearly derating to 0.5 at 125°C) and specified VSWR ≤ 1.30 (Return Loss ≥ 17.7 dB) to support dependable impedance matching and low reflections. A screw-lock coupling mechanism provides secure, repeatable connections in lab and field settings.Engineered with a nickel-plated brass body and a gold-plated phosphor bronze center contact (nickel underplated), the attenuator combines mechanical durability with low contact resistance. PTFE insulation ensures excellent dielectric stability, and silicone rubber gaskets enhance environmental sealing. The nickel-plated brass coupling nut offers robust mechanical fastening, while the unit supports 5000 W peak power and operates across -55°C to +125°C, meeting RoHS requirements.
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. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
