Description
Fixed Attenuator | 2.92mm Jack (Female) to 2.92mm Jack (Female) | 3 dB | 2 Watts | Screw-lock | Stainless Steel Body Passivated
The ROSNOL FA-K2K25A-40G2W3/9X-9X is a precision-engineered fixed attenuator designed for high-frequency RF and microwave systems. It operates across a broad frequency range of DC to 40 GHz, maintaining an impedance of 50 Ω with a VSWR of ≤ 1.3. This configuration delivers a nominal attenuation of 3 dB with an accuracy of ±0.6 dB. Rated for 2 Watts average at 25°C and 125 Watts peak, it ensures stable performance under demanding conditions. The Screw-lock mechanism provides secure mating and long-term mechanical reliability.Constructed from premium materials, this attenuator features Center Contact: Beryllium Copper with Gold plating (3 µinch) over Nickel-Phosphorus underplating (80 µinch). Body: Stainless Steel Passivated. Insulator: PTFE. The advanced plating structure enhances corrosion resistance and guarantees consistent electrical performance. It operates reliably within a temperature range of -55°C to +125°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.
