I'm not 100% sure what the sm_gamma1()and *2 function is for. Â Can someone explain to me what "simultaneous input and output reflections" means? Â Is this the reflection that needs to be presented to the input/output of the device to keep the network matched to Zo? Â

Here are the notes given in the help file:

This complex measurement determines the reflection coefficient that must be presented to the output (port 2) of the network to achieve simultaneous input and output reflections. If the Rollett stability factor stab_fact(S) is less than unity for the analyzed circuit, then sm_gamma2(S) returns1+j*0.

Save the result SM_gammax in a s1p file.

In a new design, sinthesize an impedance transformation network (LC or MLIN+STUB) to transform 50 Ohms to SM_gamma1 value. Do the same with SM_gamma2. You will have then two networks.

Create a circuit NW1+TRT+NW2. This network will be perfectly matched to 50 Ohms at input and output.
