Figure 14 shows the real and imaginary impedance values of the T-junction. The equation is satisfied in order to connect the
two filters into the common node.

Diplexer
After designing the two BPFs and the T-junction, the next step was to connect the two BPFs to the T-function and run the EM
simulation. Figure 15 shows the circuit elements and variables. It can be seen that connecting the two filters to the common
node is an easy process using the T-junction.
