Technical memorandum: The sixth port reflectometer and its complete calibration by four standard terminations

Abstract

An alternative nonlinear method to calibrate the six-port reflectometer is developed. Using this method four standards and iteratrive procedure are needed to calibrate the reflectometer.Experimental results show that this method coverges very rapidly, provides a good accuracy in calibration parameters and at the same time avoids degenerate solutions which produce unwanted singularities in the mesurement.
