Determining the Characteristics that Result from Adding a Matching Circuit
Determining the Characteristics that Result from Adding a
Matching Circuit to a Differential Port
You can obtain the characteristics resulting from the pseudo addition of a balance
matching circuit to a balanced port created by balance-unbalance conversion.
By using the matching circuit function, you can obtain the characteristics resulting from
the addition of an arbitrary matching circuit for each test port (see Figure 7-16).

Define the matching circuit to be added by one of the following methods:
• Use a predetermined circuit model and specify the values for the elements in the circuit
model.
• Use a user file (in two-port Touchstone format) to define the matching circuit to be
added.
Figure 7-17 shows the circuit models used in defining a balance matching circuit.
