Description
1.85 mm Fixed Attenuator | Plug (Male) to Jack (Female) | 20 dB | 2W | Screw-Lock | Stainless Steel Body
The ROSNOL FA-V1V25A-67G2W20/9XX-9X fixed attenuator operates from DC to 67 GHz with 50 Ω impedance and VSWR ≤ 1.40. It provides a nominal 20 dB attenuation with ±1.5 dB accuracy and supports 2 W average input power at 25 °C. The precision screw-lock coupling ensures repeatable connections for millimeter-wave signal conditioning.Piece-part construction includes a beryllium copper center contact with 3 µinch gold plating over non-magnetic nickel–phosphorus underplating (80 µinch), a passivated stainless steel body and coupling nut, and a silicone rubber gasket. This design supports corrosion resistance and stable operation across a temperature range of −55 °C to +125 °C.
ROSNOL’s precision-engineered RF attenuators deliver reliable performance across a wide range of RF and microwave systems. Designed to meet the stringent demands of high-frequency signal transmission, 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.
