Thank you for your anwer :)

Then, in short, 

Does the flow graph I mentioned use carrier freq. 450 MHz or not?

From the file source, it is just a baseband signal

Any modulation scheme you can think of that can be represented
efficiently as a series of
 mathematical operations producing a baseband waveform that is then
up-converted by the
 RFX2400 to the final frequency.

In SDR, the hardware doesn't "know" anything about modulation or
demodulation, that's up to the
 software.  The only limitation of the hardware is the bandwidth of the
resulting waveform.

The daughtercards typically anti-alias bandwidth limit the waveforms to
about 25-30MHz or so, on
 the analog mixer inputs/outputs.
