Abstract
This paper investigates the impact of possible parameter extraction errors caused by inaccurate definition of the calibration reference impedance of in-situ multiline TRL. Two calibration sets implemented on GaAs and Si/SiGe:C wafer processes were quantitatively analyzed. Obtained results demonstrated that for most practical cases, the desired 5%-level of confidence of extracted parameters of high-reflective devices can easily be achieved without additional efforts. Thus, implementation of the in-situ TRL into a characterization workflow of high-performance microwave devices can be significantly simplified.
