商品描述
Features
• Very High Stability
• Attenuation variation with frequency less than ± 1.5 dB over full waveguide band @ 500 GHz
• Very Low Coupling Sensitivity vs Temperature
• High Power Versions Available

    The Flann range of  Precision Fixed Attenuators, Series 580 & 582, are very highly stable devices eminently suitable for use in attenuation transfer standards and verification standards for attenuation measurement systems or network analysers. The units are based on directional couplers and offer low attenuation variation with frequency, typically less than 0.5 dB, and low VSWR over the full waveguide band. 

    Standard attenuation values

    3, 6, 10, 20, 30, 40, 50 and 60 dB.

    Alternative attenuation value and high power handling

    units can be manufactured to special requirements.
