Normal Waveguide Interface Variations Impact Millimeter Wave Calibration Quality

OML publishes technical paper at the 76th ARFTG Microwave Measurement Symposium.  The title of the paper is, “Understanding the Residual Waveguide Interface Variations on Millimeter Wave Calibration.”  For engineers struggling to interpret the quality of their waveguide calibration, this paper contains valuable data showing the practical results to expect when calibrating with the standard tolerances inherent in today’s waveguide interfaces. Although these waveguide imperfections are within tolerance, they will degrade the quality, but not invalidate, the calibration.  Paper is now available for general distribution.
