Description
2.4 mm Fixed Attenuator | Plug (Male) to Plug (Male) | 8 dB | 2 W Power Handling | Screw-Lock | Stainless Steel Body
The ROSNOL FA-Q1Q15A-50G2W8/9XX-9XX fixed attenuator operates from DC to 50 GHz with 50 Ω impedance and VSWR ≤ 1.30. It provides a nominal 8 dB attenuation with ±0.50 dB accuracy across DC–50 GHz, and supports 2 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 ensures secure engagement, mating cycles ≥ 500, axial center-contact captivation ≥ 20 N, coupling test torque ≤ 1.65 Nm, and recommended torque of 0.9 Nm.Piece-part construction includes a beryllium copper (BeCu) center contact with gold plating over non-magnetic nickel–phosphorus underplating (3 µinch Au over 80 µinch Ni–P), a passivated stainless steel body and coupling nut, PEI insulator, and a silicone rubber gasket—engineered for corrosion resistance and dielectric stability across −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, ensuring global environmental and safety standards. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
