Uncalibrated Variable Attenuators 520 Series

Release time：2025-5-3 9:24:27 Add to cart

Mi-Waves’ 520 series uncalibrated variable
attenuators are available in standard waveguide sizes from 26.5 to 220 GHz. The attenuating element in each unit provides variable attenuation, from 0 dB
to 25 dB minimum. Precision-designed internal controls are accurately contoured to provide a low bilateral VSWR and minimum variation of attenuation with frequency.
