To extend SI-traceable calibration for coaxial measurements up to 165 GHz, seven calculable offset short standards in the 0.8 mm coaxial system are used. The standards are calculated based on dimensional measurements and used for an overdetermined least-squares calibration. Measurement results and uncertainty budgets are reported for a flush short and a broadband match. The repeatability of the interface and a minimal pin gap are investigated.
