| Abstract: | Introduces several traditional and novel methods of measuring the group delay of frequency-translating devices (FTD) like mixers. Put forward the introduction and detail analysis of two different categories, one is based on vector network analyzer and the other is based on modulation. Also, the recent development in this research area is proposed. Finall indicates a common problem that we haven't overcome yet. |
