Mi-Waves’ 680 series twists are short sections of standard flanged waveguide with left-hand or right-hand 45º twist configurations while the 681 series twists provide 90º twist configurations. The
units are available in standard waveguide sizes from 12.4 to 320 GHz. Please be sure to specify the left-hand or right-hand configuration when ordering.

Applications
The 680 series and the 681 series waveguide twists are designed to provide changes in waveguide orientation with minimum energy loss and reflections. As integral parts in many of Mi-Waves’
ferrite devices, these twists efficiently adapt polarization-rotated RF fields to the orientation of the remaining transmission line components.
