Crosstalk Corrections for Coplanar-Waveguide Scattering-Parameter Calibrations

Abstract

We study crosstalk and crosstalk corrections in coplanar-waveguide vector-network-analyzer calibrations. We show that while crosstalk corrections can improve measurement accuracy, the effectiveness of the corrections depends on a number of factors, including the length of the access lines, transverse dimensions, the separation between the crosstalk standards, and the substrate configuration.
