Double Ridge 1/8 and 3/8 Wavelength Offset Short

Double Ridge 1/8 and 3/8 Wavelength Offset Short

Double ridge offset shorts with 1/8 and 3/8 wavelength offsets are considered one of the more accurate means of obtaining a 180° phase difference in waveguide. Using these single-piece devices will reduce the number of flange interfaces during calibration. This helps to maintain an essentially constant magnitude of current flow across the calibration plane.

The chart below lists the offset shorts available from A-INFO. Those in rectangular guide are nominally 1/8 and 3/8 wavelength offset at a frequency near the waveguide band center. These will not be the exact band center as the frequency is chosen to equalize the phase differences at the band edges.

These are also available with a custom shorting distance as a special order. Please send us your inquiry and discuss your needs.
