Description
Fixed Attenuator | N Male to N Female | 30 dB | 500 Watts | Screw-lock | Brass Body with Nickel Plating
The ROSNOL FA-N1N25A-12.4G500W30/033-03 is a high-power fixed attenuator engineered for demanding RF and microwave applications. Operating across a frequency range of DC to 12.4 GHz, it maintains an impedance of 50 Ω with a VSWR of ≤ 1.6. This configuration provides a nominal attenuation of 30 dB with accuracy levels of −4.0/+3.0 dB. Rated for 500 Watts at 25°C (derates to 50 Watts at 125°C), it ensures reliable performance under extreme conditions. The Screw-lock mechanism guarantees secure mating and long-term mechanical integrity, with durability exceeding 500 mating cycles and torque specification of 0.7 Nm to 1.1 Nm.Constructed from premium materials, this attenuator features Center Contact: Brass with Silver plating. 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.
