Description
N Male to N Female Fixed Attenuator | 3 dB | 100 W | Screw-lock | Brass Body
The ROSNOL FA-N1N25A-6G100W3/133-H3 is a precision-engineered fixed attenuator designed for dependable high-power RF performance. This N-type attenuator provides a nominal attenuation of 3 dB with an attenuation deviation of ±0.80 dB, enabling accurate, repeatable signal control across DC to 6 GHz. Rated for 100 watts average power at 25°C (derates linearly to 0.5 at 125°C) and specified VSWR ≤ 1.30 (Return Loss ≥ 17.7 dB), it maintains low reflections under demanding test or system conditions. The screw-lock coupling mechanism ensures secure mating integrity throughout routine maintenance cycles.Constructed with a nickel-plated brass body and a phosphor bronze center contact, gold-plated (nickel underplated), the design optimizes conductivity, contact reliability, and corrosion resistance. PTFE insulation delivers superior dielectric performance, while silicone rubber sealing components enhance environmental resilience. A nickel-plated brass coupling nut provides robust mechanical engagement. The assembly supports 5000 W peak power, and the product is qualified for -55°C to +125°C operation with RoHS compliance.
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.
