I tried to simulate an upconverter with input of 10 and 11 Mhz and a LO of 400Mhz. I would expect 2 tones of 410 and 411MHz at the RF output, but the simulation only gives 410Mhz. Why does not both tones appear in the simulation.

After starting to compose this response I found that if I made the tones 10.5 and 11.5 MHz, I would get outputs. Not good!
