High-Power Millimeter-Wave Dummy Load Reflected Power Measurement Method Based on a Time-Domain Gate

This article presents a low-power measurement method for the reflected power of a high-power millimeter-wave dummy load. The proposed method extracts the unknown S-parameters of the fixtures and the dummy load by combining frequency- and time-domain S-parameters. In this way, it partially eliminates the effects of asymmetric fixtures. Experiments and error source analysis of the proposed method are carried out.
