Hybrid Calibration for 4-Port On-wafer Probing
February 28, 2019
For 4-port calibration, we have combined the widely accepted LRRM calibration with the short-open-load-reciprocal thru (SOLR) calibration, creating a hybrid calibration that takes advantage of the strengths of both calibration methods for a superior 4-port calibration.
