BW 50Ω Coaxial Precision Fixed Attenuators

Mini-Circuits BW 50Ω Coaxial Precision Fixed Attenuators feature a wide range of frequencies and a maximum input power range of 0.5W to 100W. These attenuators feature precise attenuation and excellent voltage standing wave ratios (VSWR). Mini-Circuits BW 50Ω Coaxial Precision Fixed Attenuators are available with a variety of connector types. Typical applications include instrumentation, matching, test and measurement, optical communications, high-speed data systems, and test setups.
