QuinStar Technology, Inc. Linear-to-Circular Switchable Polarizer QWQ

QuinStar Technology’s QWQ series linear-to¬-circular switchable polarizers cover the frequency range of 12.4 to 170 GHz in ten waveguide bands. Series QWQ switchable polarizers have an internal polarizing card that can be manually rotated to change the signal between right- and left-hand circular polarizations without disconnecting the waveguide. A center position on the switch allows linearly-polarized signals to pass through the waveguide without changing polarization. These polarizers operate over a bandwidth of typically ± 10% centered at a specific operating frequency. QuinStar also offers a motorized (electromechanical) version of the switchable polarizer. The motorized version has only two positions corresponding to right- and left-hand circular polarizations. • Low VSWR • Minimum Insertion Loss • Fixed; Manual and Motorized Switching • Linear, LHCP and RHCP
