Graphs named "Stability Stage 1"  and "Stability Stage 2" plot the stability index of the amplifier with swepted input and output impedances. All of the load impedances are plotted, and the tuner is used to change the source impedance.  After simulation, use the tuner to vary the source impedance angles and look for any value > 1 for potential instability.  The core design in the "Two_Stage_SS_Amp" schematic has gamma probes at the input and output of each transistor to perform this analysis.

Multi-Layer Metalization

Microwave Office uses the concept of Line Types to automatically draw multi-layer metal lines.  Open the layout view of the "Input Network" schematic.  Select the MTRACE2 between the input capacitor and the radial stubs.  Right click and select Shape Properties to open the Cell Options dialog box.  Click on the Line Type drop down box and change the Line Type to "Plated Metal Line".  Notice how the line automatically draws in all of the layers with the correct offsets.  Additional Line Types can be added to the project by editing the Layer Process File (.lpf) in a text editor.  See the online User Guide for a full description of the Layer Process File (Help>Contents and Index).
