Amplitude and Phase issue with S-Parameter file

[kpriest20]

This is a simple simulation of a mini circuits power splitter. You would expect there to be some small insertion loss between port 1 and ports 2&3 as well as a slight phase shift. However, the simulation in QUCS appears to simulate an ideal splitter with no phase shifting or loss of voltage amplitude - the output voltages are literally on top of the input. You can see these effects though in the corresponding Keysight ADS simulation though. The other odd thing is how the S parameter will not work unless the parameter duringDC is set to short when this device is a transformer and at DC it's really an open. Otherwise great program, I hope IBIS simulation capability is on the roadmap.

Could you post the Touchstone file or at least the line at 0.2 GHz?
