Statistical analysis of random errors from calibration standards

This paper presents the results of error estimation caused by the VNA calibration standards using StatistiCAL designed at NIST. A GCPW-stripline-GCPW type transition and a test fixture for transceiver module testing are chosen to do the study over 8 to 12 GHz. Calibration standards, that is through, lines and shorts are fabricated in-house. The electromagnetic modeling needed in the development of the calibration standards is done through Ansoft HFSS. The results are used to verify HFSS simulations and they are effectively applied to module testing and performance screening.
