Description
Fixed Attenuator 6 dB | SMA Plug (Male) to SMA Jack (Female) | Screw-Lock | Stainless Steel Body
The ROSNOL FA-A1A25A-12.4G5W6/9XX-9X is a precision-engineered fixed attenuator for high-frequency interconnects. It operates across DC to 12.4 GHz with a nominal attenuation of 6 dB, maintaining an impedance of 50 Ω and a VSWR of ≤ 1.20 (Return Loss ≥ 20.9 dB). Power handling capability reaches 5 W average at 25°C. The product specifies attenuation accuracy of −0.6/+0.8 dB and uses a secure Screw-Lock coupling mechanism.Piece-part construction ensures reliability: the centre contact is Beryllium Copper, Gold plating over Nickel underplating; the body is Stainless Steel, Passivated; the insulator is PEI; the gasket is Silicone Rubber; and the coupling nut is Stainless Steel, Passivated. Metallic parts feature gold plating over nickel underplating on the conductive path for enhanced corrosion resistance and stable electrical performance. Operational temperature range is -65°C to +155°C.
ROSNOL’s precision-engineered RF attenuators deliver dependable performance at competitive pricing for RF and microwave systems. Manufactured in ISO 9001-certified facilities, all products fully comply with RoHS and REACH regulations. Customization for materials, plating, and mechanical design is available, making ROSNOL a compelling alternative to leading European and American brands.
