[Moved]： Simulation of H-paramters and cut off frequency of HBT transister in ADS

Is there any way to simulate the hybrid parameters of the HBT transistor in ADS ? or is there any function in ADS that can convert the s-parameters to h-parameters ?

My second question is about cut-off frequency. In the common emitter configuration, how can we obtain ft vs Ic in ADS ? Please suggest any method to do so.

Can any body tell me about the second question ? For the first one I found a function that converts from s parameters to h-parameters. stoh()

See the followings.
