The ROSNOL FA-N2N25A-5G300W40/9X-9X is a precision-engineered fixed attenuator designed for high-power RF systems. This bi-directional N-type attenuator provides a nominal attenuation of 40 dB with an attenuation deviation of ±1.2 dB, enabling accurate, repeatable signal control across DC to 6 GHz. Rated for 300 W average power at 25°C and specified VSWR ≤ 1.35 (Return Loss ≥ 16.5 dB), it supports stable impedance matching and low reflections in demanding test or system environments. The Screw-lock coupling mechanism ensures secure, repeatable mating.

Constructed with a Stainless Steel, passivated for mechanical robustness, the attenuator incorporates a Beryllium Copper, gold-plated (non-magnetic nickel-phosphorus underplating) to optimize conductivity and contact reliability. A PTFE dielectric delivers stable RF performance, and Silicone Rubber sealing enhances environmental resilience. Mechanical integrity is supported by ≥ 500 cycles, axial ≥ 28 N, and coupling test torque ≤ 1.7 Nm (recommended 0.7–1.1 Nm). The qualified operating temperature range is −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-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.
