A Multimode TRL Calibration Method Based on Improved Mode Tracking Algorithm for Differential Line Characterization

A multimode thru-line-reflect(TRL) calibration method based on improved mode tracking technology for differential line characterization is proposed. An improved mode tracking method is used to sort eigenvalues quickly and reliably, which improves the practicability of the algorithm. To verify the proposed algorithm, an experiment is conducted. The consistency of the data obtained by multimode TRL and 2×Thru shows the effectiveness of the algorithm for the calibration of differential devices.
