Description
N Fixed Attenuator | Plug (Male) to Jack (Female) | 10 dB | 100 W | DC–8.5 GHz | Screw-Lock | Brass Body
The ROSNOL FA-N1N25A-8.5G100W10/H33-H3 fixed attenuator provides 10 dB attenuation in a 50 Ω N Plug (Male) to N Jack (Female) configuration. It supports DC to 8.5 GHz operation with a maximum VSWR of 1.35, and handles 100 W average power with 5000 W peak capability. Mechanical integrity is ensured by a screw-lock coupling mechanism, a recommended torque of 1.0 Nm, and at least 500 mating cycles for dependable service in RF and microwave systems.The center contact uses gold-plated phosphor bronze to maintain low contact resistance and stable RF performance. The body and coupling nut are nickel-plated brass for strength and corrosion resistance, the insulator is PTFE for dielectric stability, a silicone rubber gasket enhances sealing, and a black-anodized aluminum heatsink supports efficient thermal dissipation. This attenuator is suitable for transmitter power leveling, receiver protection, and broadband test benches requiring precise 10 dB attenuation.
ROSNOL’s precision-engineered RF components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations. Delivering high quality and competitive pricing, the FA-N1N25A-8.5G100W10/H33-H3 is an excellent alternative to premium European and American brands. Customization for materials, plating, and mechanical design is available to meet specialized requirements.
