I'm on a project that works at 1.9GHz what will be consisted of passive circuits on a silicon substrate.
I have some question in my mind about " differential ports"
These are compiled as single ports but when this the case , source impedance will be what ? I mean if they are recognized as a single port How I can simulate this "Data Set of Momentum" in a schematic simulation page? Because there are 11 ports and in Momentum simulation every single port is terminated by 50Ohm and in reality, these ports won't be terminated 50 Ohm , maybe some different terminations..
Second question..
How can we choose MW mode and RF Mode ? In fact in Reference Guide of Momentum the difference between them is not VERY clear..And obviously , the results seem to be different. But the worst is measurment is a little bit far away from simulation results.
In that case which simulation mode will be used in which case??
Is there anybody who has great exprience on ADS Momentum ? I'm gonna be appreciate..
