Description
Fixed Attenuator | N Male to N Female | 30 dB | 500 Watts | Screw-lock | Brass Body with Nickel Plating
The ROSNOL FA-N1N25A-2.4G500W30/133-H3 is a high-performance fixed attenuator designed for RF and microwave applications. Operating across a frequency range of DC to 2.4 GHz, it maintains an impedance of 50 Ω with a VSWR of ≤1.3. This configuration provides a nominal attenuation of 30 dB with accuracy levels of −1.0/+1.2 dB. Rated for 500 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: Beryllium Copper with Gold plating over Nickel-Phosphorus underplating. Body: Brass with Nickel plating. Insulator: PTFE. Gasket: Silicone Rubber. Coupling Nut: Brass with Nickel plating. 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 high-power 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.
