Figure 1. Photo of the four coupled transmission lines used in this example with their ends labeled with the recommended port assignment. Each line is about 11 inches long when unwound. Each ...

Figure 1 shows an example of a ... mode scattering matrix. This article presented basic definitions and briefly discussed the key types of scattering parameters. The S-parameters can be used ...

A scattering matrix (or S parameter matrix) can be used to describe coupler performance with any passive termination. The S parameters within the matrix are measured using terminations which are equal ...
