Description
2.92 mm Fixed Attenuator | Plug (Male) to Jack (Female) | 30 dB | 10 W | Screw-Lock | Stainless Steel Body, Passivated
ROSNOL FA-K1K25A-40G10W30/9XX-9X is a 2.92 mm fixed attenuator operating from DC to 40 GHz at 50 Ω impedance with VSWR ≤ 1.35. It supports 10 W average power at 25 °C and 200 W peak under specified pulse conditions. Nominal attenuation accuracy for 30 dB is −1.0 / +1.2 dB across the band. The screw-lock coupling ensures secure mating with torque range 0.80–1.10 Nm and durability of ≥ 500 cycles. Temperature range −55 °C to +125 °C.The center contact is beryllium copper with gold plating over a non-magnetic nickel-phosphorus underlayer (approx. 3 μin Au over 80 μin Ni-P) for enhanced conductivity and corrosion resistance. The body and coupling nut are stainless steel with passivated finish, while silicone rubber gaskets provide sealing. This plating stack combined with stainless steel ensures excellent durability and environmental protection.
ROSNOL’s precision-engineered RF attenuators deliver high performance and consistent value for RF and microwave systems. Manufactured in ISO 9001–certified facilities, all ROSNOL components comply with RoHS and REACH. ROSNOL provides cost-effective alternatives to leading European and American brands and offers comprehensive customization for materials, plating, and mechanical design.
