Hi Mixing those two frequencies *should* give you 10.000001 MHz and 1 Hz at equal levels. Any amplitude inequality will be due to filtering.
Feed two tones like that into various amps and you will drive them into compression. You need a good linear amp to handle both at once. Indeed some form of fancy filtering to prevent the 1 Hz from getting to the amp is also an answer. The gotcah is that a narrowband filter likely will give you a bit of temperature dependent delay.
