When these frequencies are away enough from each other (for example f0=1GHz and f1=3MHz),
HB simulation results are just like that of transient simulation.
But, when these frequencies are close to each other (f0=1GHz and f1=10kHz),
HB result is different from transient simulation (and in this situation, transient simulation takes long time).
I think f0 and f1 in latter case are away enough from each other than former case.
Don't you have some mistakes ?

Where is the problem about HB?
Show me netlist of ADS.
Show me graphs of results for both HB and Transient.
