Description
Fixed Attenuator 30 dB | SMA Plug to SMA Jack | Screw-Lock | Brass Body
The ROSNOL FA-A1A25A-12.4G2W30/911-91 is a precision-engineered fixed attenuator designed for high-frequency applications. It operates across DC to 12.4 GHz with a nominal attenuation of 30 dB, maintaining an impedance of 50 Ω and a VSWR of ≤ 1.30 (Return Loss ≥ 17.69 dB). Power handling capability reaches 2 W average at 25°C, ensuring stable performance under demanding conditions. The attenuator guarantees attenuation accuracy of ±0.5 dB and features a robust Screw-Lock coupling mechanism for secure connections.Constructed with premium materials for superior reliability, the centre contact is made of Beryllium Copper, Gold plating over Nickel underplating, while the body and coupling nut use Brass, Gold plating over Nickel underplating. The insulator is PTFE and the gasket is Silicone Rubber. All metallic components feature gold plating over nickel underplating for excellent corrosion resistance and long-term durability. This attenuator performs reliably within a temperature range of -55°C to +85°C.
ROSNOL’s precision-engineered RF attenuators deliver consistent performance and cost-effective solutions for RF and microwave systems. Manufactured in ISO 9001-certified facilities, all products comply with RoHS and REACH regulations, ensuring global environmental and safety standards. Customization services for materials, plating, and mechanical design are available to meet specialized requirements, making ROSNOL an ideal alternative to leading European and American brands.
