QuinStar Technology’s QWT series waveguide twists cover the frequency range of 18 to 220 GHz in ten waveguide bands. The twists allow a change of orientation in a waveguide assembly. They are available with angles of 45° in either a left- or right-hand twist or a standard 90°. The twists are built with high precision and then gold plated for low insertion loss and high corrosion resistance. Typical VSWR is 1.10:1 over entire frequency band.
