Description
Fixed Attenuator | N Male to N Female | 6 dB | 2 Watts | Screw-lock | Brass Body with Nickel Plating
The ROSNOL FA-N1N25A-11G2W6/H33-H3 is a precision-engineered fixed attenuator designed for RF and microwave applications. Operating across a frequency range of DC to 11 GHz, it maintains an impedance of 50 Ω with a VSWR of ≤ 1.35. This attenuator offers Nominal Attenuation 6 dB, Deviation ±0.5 dB and supports a power handling capacity of 2 Watts. Featuring a robust Screw-lock mechanism, it ensures secure connections with a coupling nut retention of ≥ 450 N, center contact captivation of axial ≥ 28 N, and mechanical durability exceeding ≥ 500 mating cycles. Recommended torque is 0.7 Nm to 1.1 Nm, guaranteeing reliable performance in demanding environments.Constructed from premium materials for superior durability, the FA-N1N25A-11G2W6/H33-H3 incorporates Center Contact: Phosphor Bronze with Gold plating (3 µinch) over Nickel-Phosphorus underplating (100 µinch). Body: Brass with Nickel plating. Insulator: PTFE. Gasket: Silicone Rubber. Coupling Nut: Brass with Nickel plating. This advanced plating structure enhances corrosion resistance and ensures stable electrical performance. The attenuator operates reliably within a wide temperature range of -55°C to +125°C, making it suitable for diverse RF systems.
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.
