2.92mm Plug (Male) to 2.92mm Jack (Female) Fixed Attenuator, 40GHz 50W 40dB VSWR 1.35

2.92 mm Fixed Attenuator | Plug (Male) to Jack (Female) | 40 dB | 50 W | Screw-Lock | Stainless Steel Body, Passivated

ROSNOL FA-K1K25A-40G50W40/9XX-9X is a 2.92 mm fixed attenuator designed for high-power RF applications, operating from DC to 40 GHz at 50 Ω impedance with VSWR ≤ 1.35. It handles 50 W average power at 25 °C and up to 200 W peak under pulsed conditions. Nominal attenuation accuracy for 40 dB is −2.0 / +3.0 dB. The screw-lock coupling ensures secure engagement with recommended torque of 0.80–1.10 Nm and durability of ≥ 500 mating cycles. Center contact captivation meets axial ≥ 20 N and radial ≥ 0.01 Nm requirements. Temperature range −55 °C to +125 °C.

The center contact is beryllium copper with gold plating for excellent conductivity, supported by a nickel-phosphorus underlayer for corrosion resistance. The body and coupling nut are stainless steel with passivated finish, while the insulator is PEI for thermal stability. Silicone rubber gaskets provide environmental sealing, and an integrated black anodized aluminum heatsink ensures efficient thermal management under high-power conditions.

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.
