| Abstract: | Source complex reflection coefficient measurement based on power has been introduced. By measuring power of different 2-port microwave networks, accurate source complex reflection coefficient can be got by solving equations.
Measurement uncertainty can be greatly reduced by using relative power measurement. Detailed measurement of a 50MHz reference source in power meter has been carried out as an example. This method in the paper can also be used in other kinds
of source complex reflection coefficient measurement. |
