design an oscilator in ADS convergence problem

ads convergence

Hello everybody,

I actually try to design an oscillator 14 GHz on ADS,
my goal in S parameter simulation is reached ( Nyquist criterium are OK for now )

but when i want to do an Harmonic balance simulation to see the output Power and the phase noise, i use an oscport like in many examples, and i try many things also, but the simulation never converged .

Someone have some experiences or ideas to solve this problem, i have really no idea...

thanks

Try transient aided harmonic balance.
