Frequency generation on EV-RADAR-MMIC2

I bought EV-RADAR-MMIC2 and I was ready to use this system.
The data sheet for the PLL chip (ADF 4159) itself has been verified, which corresponds to the generation of a 13 GHz band signal and I want to ask whether it can show similar modulation performance when the chip is connected to a 24 GHz band VCO (inside the ADF 5901). I know that the design of the loop filter has a great effect on the performance of the modulation, but can I be sure of the maximum frequency modulation performance of the designed loop filter currently mounted on the EV-RADAR-MMIC2? I would like to ask the minimum chirp time compared to the 250 MHz bandwidth (ramp).
