I agree with SemiLeon, that you will see the same offset tone at 1GHz, but it will be smaller. My reasoning is if you add 0.1 GHz to 2 GHz sinewave, and then limit the signal, what you have essentially is an FM signal (or PM). The same edge excursions at the input will show up on the output as well, with the same frequency, 0.1 GHz. Since the period at the output is twice the input, therefore the frequency (or phase) deviation will be 1/2 of the input. On the other hand, if AM is causing the tone, then the output tone will be basically a feed-through of the input tone, at 0.1 GHz offset, also a smaller amplitude, unless the isolation of the divider really sucks.
