Mi-Wave’s 520 Series Uncalibrated Variable Attenuators and 522 Calibrated Attenuators are available in standard waveguide sizes from 8 to 220 GHz. The attenuating element in each unit provides a 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.
