Annotation: 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.
