Description
3.5 mm Fixed Attenuator | Plug (Male) to Jack (Female) | 6 dB | 1 W Power Handling | Screw-Lock | Stainless Steel Body
The ROSNOL FA-PC1PC25A-33G1W6/9XX-9X fixed attenuator supports DC to 33 GHz operation at 50 Ω with VSWR ≤ 1.3. It provides a nominal 6 dB attenuation with ±0.8 dB at 33 GHz and 1 W average power handling at 25 °C. The screw-lock coupling ensures secure engagement with stable contact retention and repeatable mechanical durability over extended mating cycles. Insertion loss corresponds to the specified attenuation. Insulation resistance and voltage ratings follow ROSNOL’s high-reliability design practices; Accuracy of Attenuation & Power is verified across the specified band.Piece-part construction features a beryllium copper (BeCu) center contact with gold plating over nickel underplating, a passivated stainless steel body and coupling nut, PTFE/engineering-grade insulators, and a silicone rubber gasket. This stack-up provides strong corrosion resistance and thermal stability across −55 °C to +100 °C.
ROSNOL’s precision-engineered RF attenuators deliver consistent performance and excellent value as alternatives to leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH. Customization of materials, plating, attenuation values, and mechanical design is available to support specialized requirements.
