Can you perform simulations in G2006.04 mixing two types of simulations? Specifically, the HB simulator and the linear simulator.

For instance: I have a phase shifter design with non linear performace (across frequency and control voltage) that is analyzed using the harmonic balance simulator. This circuit shows a variable phase as a function of both control voltage and frequency.

I would like to use that phase shifter's (phase shift vs V,F) macro caracteristics in a chain having S parameter blocks in series, and then analyze the entire system. So the S parameter blocks would perform linear operations on the voltage signal passing through the system, and the harmonic balance results would be used to add linearly with the rest of the system.

Can this system simulation be run successfully? If so,which simulation should be used, the linear simulator, or a swept harmonic balance simulation?

Thanks,

This should be no problem at all. You would use the harmonic balance simulation (which fully supports S parameter linear devices). If you need more detail just post another message and I'll take a look.

If you do a linear analysis on this nonlinear circuit you'll get the DC-appropriate linear analysis (i.e. linear with bias points).
