Summary:In this study, a novel amplitude-only method to measure the phase difference between two incident signals is developed. For a 90° hybrid, it can be shown as two signals with relative phase difference ΔΦ incident to the input and isolated ports, their phase difference can be calculated from the measured power data by having two detectors connected to the direct and coupled ports. The general formulas and measurement results of a special condition are presented.
