Dial-Type Uncalibrated and Calibrated Waveguide Attenuators (Series 520 & 522)

Descriptions

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.

Applications
The 520/522 Series Variable Attenuators are useful in applications that require a reliable level setting or isolating pad. They provide maximum accuracy in establishing initial power levels in substitution-method attenuation measurements. Designed to maintain reliable performance for accurate test measurements, the stable setting control of these devices maintains constant attenuation under all normal conditions of vibration and orientation.
