Embodiment Construction
[0030] The present invention will be further described below in conjunction with drawings and embodiments.
[0031] Embodiments of the present invention and its implementation work process are as follows:
[0032] According to the theoretical knowledge of microwave engineering, the S-parameter matrix and the transmission coefficient matrix ABCD of the dual-port network can be converted to each other. The specific calculation formula is as follows:
[0033]
[0034]
[0035]
[0036]
[0037] Among them, A means to apply a voltage V on port 1 (ie input port) 1 and measuring the open circuit voltage V on port 2 (ie the output port) 2 The ratio, B represents the voltage V applied on port 1 1 with the short-circuit current I measured on the 2-port 2 The ratio of, C represents the current I applied on port 1 2 with measuring the open circuit voltage V on the 2-port 2 The ratio of D represents the current I applied on port 1 1with the short-circuit current I measur...
