Description
Fixed Attenuator | N Male to N Female | 3 dB | 2 Watts | Screw-lock | Brass Copper-Tin-Zinc Alloy Body
The ROSNOL FA-N1N25A-4G2W3/H44-H4 is a precision-engineered fixed attenuator designed for RF and microwave applications. Operating across a frequency range of DC to 4 GHz, it maintains an impedance of 50 Ω with a VSWR of ≤ 1.25. This configuration provides a nominal attenuation of 3 dB with accuracy levels of ±0.3 dB. Rated for 2 Watts, 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: Phosphor Bronze with Gold plating over Nickel-Phosphorus underplating. Body: Brass Copper-Tin-Zinc Alloy. Insulator: PTFE. Gasket: Silicone Rubber. Coupling Nut: Brass Copper-Tin-Zinc Alloy. The advanced plating structure enhances corrosion resistance and ensures 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.
