VST-U-292XX0201-40G is a 50 Ω 2.92 mm male-to-female precision fixed attenuator series covering DC to 40 GHz. The series is available in 1–10 dB nominal attenuation values, plus 20 and 30 dB options, for fixed level reduction in RF and microwave measurement paths.
The attenuators are rated for 2 W with a maximum VSWR of 1.40. Models from 1–10 dB are specified to ±0.8 dB attenuation tolerance. Passivated stainless-steel construction and gold-plated BeCu inner contacts provide a compact inline solution for compatible 2.92 mm coaxial test systems.
