What happens in IF mixer, when LO contains 2 harmonics (one with bigger amplitude)?

[Terminator3]

For example, LO contains two frequencies: 5GHz and 10GHz
What happens with IF if 5GHz amplitude is bigger, but incoming RF signal is 10GHz?

LO: 5GHz A1 + 10GHz A2 A1>A2
RF: 10GHz (modulated) A3

Would we get IF=RF-LO=10-10+modulation.

you get output frequences that are (N x Frf) +/- (M Flo), where N and M are 0 to around 10. there are a tone of spurious tone predictor programs out there.

In some odd cases, where the LO has 2 tones that are correlated to each other, you can get some interesting beat note effects in amplitude also.
