Hi everyone, I am running a Harmonic Balance (HB) simulation for a passive mixer, but the linearity is very poor. I'm not sure where the problem lies.

Logically, a passive mixer should exhibit excellent linearity, yet mine performs very poorly;

The supervisor's requirements are a conversion gain greater than 5 dB and linearity greater than 0 dBm (1 dB compression point).

I wonder if there is an issue with my simulation method.I hope everyone can help me. Thank you all.
