QuinStar Technology’s QPS series of direct reading phase shifters are designed and built for precision millimeter-wave measurements. These instruments cover the range of 26.5-110 GHz in six waveguide bands. Series QPS direct reading phase shifters are of classical rotary vane con¬struction. They offer highly repeatable settings and frequency independent readings. These instruments have low VSWR. In addition, the phase shifter has low insertion loss.
These instruments are well suited for accurate millimeter-wave measurements. Direct reading phase shifters are available in motorized versions for ATE or other applications requiring remote control.
