Abstract: This paper introduces the measurement principle of reflectometer, presents a solution to solve the DUT matching characteristic measurement under high power pulse condition by designing an asymmetric double directional coupler, points out the advantages of this method, and analyzes the uncertainty of measurement results of the reflection coefficient.

Key words: Asymmetry, Double directional coupler, Reflection
