Description
N Female to N Female Fixed Attenuator | 30 dB | 100 W | Screw-lock | Brass Body
The ROSNOL FA-N2N25A-4G100W30/93-93 is a precision-engineered fixed attenuator for RF systems. This N-type attenuator provides a nominal attenuation of 30 dB with an attenuation deviation of ±0.75 dB, delivering accurate and repeatable signal control across DC to 4 GHz. Rated for 100 watts average power at 25°C and specified VSWR ≤ 1.30 (Return Loss ≥ 17.69 dB), it maintains stable impedance matching. The screw-lock coupling mechanism ensures secure, repeatable mating.Manufactured with a nickel-plated brass body and beryllium copper center contact with gold plating, the design optimizes conductivity and durability. PTFE insulation provides excellent dielectric properties, and the black anodized aluminum heatsink enhances thermal management.
ROSNOL’s precision-engineered RF attenuators deliver reliable performance across a wide range of RF and microwave systems. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations. Customization services for materials, plating, and mechanical design are available.
