-f float frequency to output on GPIO_18 pin 12 in khz : (130 kHz to 750 MHz),
Is this a typo or can you actually have that high a frequency? In the BCM2835 manual it is stated that the PWM can be most 125 MHz, given the old document assumption on clock freq etc.
Have anyone actually tested this?
How does it differ for different devices?

PWM and PCM could be up to 500MHZ using the right PLL.
With PWM there is a divider by 2 to make a waveform : thus 250MHZ.
When frequency is above 250MHZ, rpitx compute the harmonic needed : for example -f 300000 will output 100MHZ but you could listen to the signal on 100*3=300MHZ
In the Readme.md usage you say:
