The signal at the gates can have a common-mode component, however, meaning that it is the same on both sides. This can occur because of the balun not being balanced perfectly or common-mode noise. Hence, common-mode stability needs to be assessed.

Below you see the setup to test common-mode stability and the equations to evaluate the data in the ADS data display. The mu parameters indicate that this circuit not unconditionally stable for common-mode signals.
