Description
SMA Fixed Attenuator | 2 W Power | 0 dB | Screw-Lock | Stainless Steel Body
The ROSNOL FA-A1A25A-6G2W0/9XX-9X is a precision-engineered SMA fixed attenuator designed for high-frequency applications up to 6 GHz. It features a 50 Ω impedance, VSWR ≤ 1.30 (≥17.69 dB return loss), and supports 2 W average power at 25°C. The nominal attenuation is 0 dB with accuracy of ±0.6 dB across the specified frequency range. This attenuator employs a robust screw-lock coupling mechanism, ensuring secure connections and mechanical durability of ≥500 mating cycles.Constructed with premium materials, the center contact is made of beryllium copper with gold plating over a nickel underlayer for optimal conductivity and corrosion resistance. The body is stainless steel with passivated finish, while the coupling nut is brass with gold plating over nickel. The insulator is PTFE for excellent dielectric performance, and a silicone rubber gasket provides environmental sealing. The design ensures reliable operation across a temperature range of -55°C to +85°C.
ROSNOL’s RF components deliver exceptional quality and cost efficiency, offering a competitive alternative to leading European and American brands. All products are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations. Customization services for attenuation values, materials, and plating are available to meet specialized requirements.
