I want to find the conversion gain. I do PSS simulation. RF=2.405Ghz LO =1.2GHz . If I set the IF freq is 5Mhz as a beat frequency, PSS is stopped at 2nd running. Error occurs. If I set the beat frequency as automatic, It is worked well. What is the reason for that? For subharmonic mixer, How can I give the frequencies? Please help me . Urgent.

N=2405/5=481 harmonics...( at least) If you consider 2nd,3rd,4th etc. harmonics of the carriers, this will be huge number of harmonics. I suggest you to use automatic beat frequency.
