Description
N Male to N Female Fixed Attenuator | 2 dB | 50 W | Screw-lock | Brass Body
The ROSNOL FA-N1N25A-6G50W2/133-H3 is a precision-engineered fixed attenuator designed for RF and microwave systems. This N-type attenuator provides a nominal attenuation of 2 dB with an attenuation deviation of ±0.4 dB, ensuring accurate and repeatable signal control across DC to 6 GHz. Rated for 50 watts average power at 25°C, it maintains VSWR ≤ 1.20 (Return Loss ≥ 20.8 dB). The Screw-lock coupling mechanism guarantees secure mating integrity under routine maintenance and testing cycles.Constructed with a Brass, nickel plated for durability and thermal stability, the design incorporates a Phosphor Bronze, gold-plated (nickel underplated) to optimize conductivity and contact reliability. The insulator is PTFE for superior dielectric performance, and the sealing components use Silicone Rubber for environmental resilience. A Brass, nickel plated provides robust mechanical engagement. This configuration supports 5000 W peak power while sustaining consistent attenuation accuracy.
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.
