I am designing a 3-port circulator circuit that mixes an RF input with a local oscillator. The oscillator is custom design and not a ideal source. I have tried hb simulation with the oscillator defined and then ran hbsp with no success. The oscillator is not converging with I run the hb. However, when i run a transient analysis the oscillator is functioning correctly.
How can I run a Harmonic balance simulation with the oscillator and view the s-parameters of the circulator at all three ports.
