QuinStar Technology’s QAD series of direct reading attenuators are designed and built for precision millimeter-wave measurements. These instruments cover the range of 26.5-170 GHz in eight waveguide bands. Series QAD direct reading attenuators are of classical rotary vane con¬struction. They offer highly repeatable settings and frequency independent readings. These instruments have low VSWR. In addition, the attenuator has negligible phase shift versus attenuation setting.
These instruments are well suited for accurate millimeter-wave measurements. Direct reading attenua¬tors are available in motorized versions for ATE or other applications requiring remote control.
