Abstract :
This paper reports the results of a detailed study of a commercial implementation of the Line-Reflect-Reflect Match (LRRM) vector network analyzer calibration method with automatic load inductance correction. Limitations in applicability for non-offset standards and when the Line (Thru) standard is electrically long and/or the load inductive reactance is large are examined. An enhanced LRRM (eLRRM) algorithm has been developed providing superior and more predictable results for these less frequently encountered cases. eLRRM is available in a commercial VNA calibration software product.
