Can anyone answer my question?
In the datasheet of ADF4159, I see this chip has a fast ramp FMCW mode.
So what are the factors enable ADF4159 to have the ability to do fast ramp mode?
Why can't ADF4158 do fast ramp?
This functionality was added to the sweeper circuit in the ADF4159. The ADF4158 can not perform a fast ramp sweep.
A fast ramp sweep? You mean when I enable the fast ramp mode of ADF4159, the chip starts to output a triangular ramp with two different slope. However, the chip ADF4158 is not capable to do that.
