Abstract
- This paper summarizes the calibration of precision coaxial air lines in a 3.5-mm line size. The standard system of the National Metrology Institute of Japan (NMU) is used to accurately obtain mechanical measurements of the diameters and lengths of lines. Length compression of approximately 6.0 μm and diameter distortions caused by connections with specified torques have been observed in 3.5-mm air lines. A small insertion loss in the millimeter-wave frequency range has also been detected. Furthermore, NMIJ has established standards for scattering parameters in the frequency range up to 110 GHz for coaxial air lines in the 1.0-mm line size by the enhancement of mechanical measurement systems.
