Description
QMA Fixed Attenuator | Plug (Male) to Jack (Female) | 1 dB | 2W | Quick-Lock | Brass Body
The ROSNOL FA-QA1QA25A-3G2W1/944-94 fixed attenuator operates from DC to 3 GHz with 50 Ω impedance and VSWR ≤ 1.25 (≥ 19.08 dB). It provides a nominal 1 dB attenuation with ±0.4 dB accuracy across DC–3 GHz, and supports 2W average input power at 25 °C. Insertion loss is not specified in this data sheet; insulation resistance is ≥ 5 GΩ. The Quick-Lock coupling ensures secure engagement; weight is not specified.
Piece-part construction includes a beryllium copper (BeCu) centre contact with gold plating over nickel underplating, a brass body (copper–tin–zinc alloy), and a PTFE insulator—engineered for corrosion resistance and dielectric stability across −55 °C to +130 °C.
