Description
1.0 mm Fixed Attenuator | Plug (Male) to Jack (Female) | 3 dB | 1W | Screw-Lock | Stainless Steel Body
The ROSNOL FA-W1W25A-110G1W3/9XX-9X fixed attenuator operates from DC to 110 GHz with 50 Ω impedance and VSWR ≤ 1.60 (≥ 12.7 dB). It provides a nominal 3 dB attenuation with ±2 dB accuracy across DC–110 GHz and supports 1 W average input power at 25 °C. Insertion loss is specified as ≤ 0.05 × √F(GHz) dB, with insulation resistance ≥ 5 GΩ. The screw-lock coupling mechanism ensures secure engagement with mating cycles ≥ 500, axial center-contact captivation ≥ 10 N, coupling test torque up to 0.7 Nm, and a recommended torque range of 0.3 to 0.41 Nm.Piece-part construction includes a beryllium copper center contact with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating, a passivated stainless steel body and coupling nut, a PEI insulator, and a silicone rubber gasket. This configuration provides corrosion resistance and mechanical stability across an operating temperature range of −40 °C to +85 °C.
ROSNOL’s precision-engineered RF attenuators deliver reliable performance across millimeter-wave and high-frequency RF systems. Designed to meet demanding bandwidth and stability requirements, ROSNOL attenuators offer a cost-effective alternative to products from leading European and American brands. 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 to support specialized interconnect requirements.
