Description
Fixed Attenuator 0 dB | SMA Plug (Male) to SMA Jack (Female) | Screw-Lock | Stainless Steel Body
The ROSNOL FA-A1A25A-18G1W0/9XX-9X is a precision-engineered fixed attenuator for RF and microwave systems. It operates across DC to 18 GHz with a nominal attenuation of 0 dB, maintaining an impedance of 50 Ω and a VSWR of ≤ 1.25 (Return Loss ≥ 19.08 dB). Power handling capability is 1 W average at 25°C. Attenuation accuracy is specified at ±0.40 dB.Piece-part materials and plating: centre contact—Beryllium Copper, Gold plating over Nickel underplating; body—Stainless Steel, Passivated; insulator—PTFE; gasket—Silicone Rubber; coupling nut—Stainless Steel, Passivated. Gold plating over nickel underplating on conductive elements enhances corrosion resistance and ensures stable electrical performance. Operational temperature range: -65°C to +125°C.
ROSNOL’s precision-engineered RF attenuators deliver reliable performance and cost-effective solutions for RF and microwave systems. Manufactured in ISO 9001-certified facilities, all products comply with RoHS and REACH regulations. Customization services for materials, plating, and mechanical design are available, making ROSNOL an ideal alternative to leading European and American brands.
