Description
2.4 mm Fixed Attenuator | Jack (Female) to Jack (Female) | 20 dB | 2W | Screw-Lock | Stainless Steel Body
The ROSNOL FA-Q2Q25A-50G2W20/9X-9X fixed attenuator operates from DC to 50 GHz with 50 Ω impedance and VSWR ≤ 1.30. It provides a nominal 20 dB attenuation with ±0.70 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, recommended torque 0.9 Nm, and a typical mass of approximately 0.0040 kg.Piece-part construction includes a beryllium copper (BeCu) center contact with 3 µinch gold plating over 80 µinch non-magnetic nickel–phosphorus underplating, a passivated stainless steel body and coupling nut, and a PEI insulator—engineered for corrosion resistance and dielectric stability across an operating temperature range of −55 °C to +125 °C.
