Hi, I have met a problem on using Equation Defined n-port RF Device. It seems that in Qucs, such device has only n terminals instead of n pairs of terminals. Thus for a n-port RF Device, how could I add load and sources to its ports? I found a similar question in "https://sourceforge.net/p/qucs/discussion/311050/thread/135425060b/". It says that Qucs implicitly defined the ground as the reference terminal. Thus how should I do if these ports do not have the same reference terminal? Any help would...
