QuinStar Technology's QWL and QWQ series linear-to-circular
fixed and switchable polarizers cover the frequency range of 26.5 to 110 GHz in six
waveguide bands. Fixed polarizers are sections of circular waveguide with a built-in
polarization converter that converts a linearly polarized signal to either a left- or
right-hand circularly polarized signal, depending on the orientation of the waveguide
section.
Series QWQ
switchable polarizers have an internal polarizing card that can be manually rotated to
change the signal between right- and left-hand circular polarization 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.
Electromechanically
switchable polarizers have a microswitch- or TTL-compatible driver. The switch between
linear-circular polarization conversion state and linear-linear non-conversion state. When
used with the electromechanical switch and orthomode transducer, a linear input can be
converted into linear vertical,linear/horizontal, RHCP or LHCP polarization at the output
port. |
