Description
Fixed Attenuator | N Male to N Female | 3 dB | 2 Watts | Screw-lock | Stainless Steel Body Passivated
The ROSNOL FA-N1N25A-12.4G2W3/9XX-9X is a precision-engineered fixed attenuator designed for RF and microwave applications. Operating across a frequency range of DC to 12.4 GHz, it maintains an impedance of 50 Ω. VSWR performance varies by frequency: DC–4 GHz ≤1.15, 4–8 GHz ≤1.20, 8–10 GHz ≤1.20, 10–12.4 GHz ≤1.25. This configuration provides a nominal attenuation of 3 dB with accuracy levels of ±0.3 dB (DC–4 GHz), ±0.4 dB (4–8 GHz), ±0.5 dB (8–12.4 GHz). Rated for 2 Watts average up to 30°C, it ensures stable performance under demanding conditions. The Screw-lock mechanism guarantees secure mating and long-term mechanical reliability.Constructed from premium materials, this attenuator features Center Contact: Beryllium Copper with Gold plating over Nickel underplating. Body: Stainless Steel Passivated. Insulator: PTFE. Gasket: Silicone Rubber. Coupling Nut: Stainless Steel Passivated. The advanced plating structure enhances corrosion resistance and ensures consistent electrical performance. It operates reliably within a temperature range of -55°C to +130°C, making it suitable for diverse RF environments.
ROSNOL’s RF components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations. Our attenuators deliver exceptional quality and cost efficiency, serving as a competitive alternative to leading European and American brands. Customization services for materials, plating, and mechanical design are available to meet specialized application requirements.
