Self-calibration of differential cable-adapters with intra-mode crosstalk

A new solution for the calibration of a multiport vector network analyzer (VNA) is presented, in order to measure the mixed-mode scattering parameters (S-parameters) of a 8-port device under test (DUT). The calibration procedure accounts for coupling between identical modes (intra-mode) of modal por...

Summary:A new solution for the calibration of a multiport vector network analyzer (VNA) is presented, in order to measure the mixed-mode scattering parameters (S-parameters) of a 8-port device under test (DUT). The calibration procedure accounts for coupling between identical modes (intra-mode) of modal ports, whereas different modes are assumed to be decoupled (inter-mode). The new method extends known procedures for the self-calibration of leaky 4-port error-networks and for unknown-thru calibration to modal error-networks. Among others, it requires application of a mode-conversion standard, which can be a reciprocal yet otherwise unknown device.
