the generalized t matrix form is most easily seen with balanced ports since they can be grouped so that they have a high degree of symmetry to the 2 port this is accomplished by dividing a balanced network into quadrants where each quadrant consist of a sub matrix in the 2 port case the first t i i second t i ii third t ii i and fourth t ii ii quadrants are t 11 t 12 t 21 and t 22 respectively fig2 shows how to properly divide balanced 4 and 6 port networks into quadrants there are some important characteristics for higher order balanced ports that are based on the 2 port network the first is that each quadrant forms square sub matrices whose sizes are always this show that the smallest allowable quadrant size for balanced ports is the 2 port resulting in a sub matrix with the size 1 u00d7 1 secondly each quadrant sub matrix has the same physical meaning as their corresponding 2 port equivalent this means that the grouped quadrants of t i i and t ii ii are considered similar in function to t 11 and t 22 likewise setting up the t matrix according to 8 is advantageous for unbalanced ports because it provides a grouping symmetry to the 2 port therefore for unbalanced ports the t and s matrices can be grouped into quadrants where each quadrant consists of a sub matrix that is not necessarily square this allows the quadrants t i i t i ii t ii i and t ii.
