摘要

In this paper a comparison between two different methods for measurement of Directivity and Test Port Match of directional couplers and bridges is presented. One of them is scalar - the popular Ripple Technique - and the other one vectorial - the so-called Direct Calibration Method as derived by Juroshek in [1], with slight differences for the simultaneous measurement of both parameters. The two methods make use of a Vector Network Analyser (VNA) and the calibrations performed are verified against known standards. Also the uncertainty associated to both techniques is computed.
