Abstract: The article discusses a method to measure the group delay of microwave devices, providing high frequency detail without compromising accuracy. Reducing the measurement step of a vector network analyzer leads to an increase in the random component of the error, that is subsequently reduced due to time-domain filtering. The modeling results for the developed method are presented.

Keywords: group delay, microwave device, vector network analyzer, time domain gating

Funding: The work was carried out within the framework of the implementation of the "Development Program of the Advanced Engineering School "Electronic Instrumentation and Communication Systems" named after A.V. Kobzev."
