Frequency stepping with ADF4158

HI all,


I'm working on Stepped frequency continuous wave radar where I need to generate frequencies from 500MHz to 3GHz in steps 2.5MHz. I see from Documents of ADF4158 that it is able to output ramp. Will it be possible to step through frequencies, with ADF4158, in increments of 2.5MHZ? Is there a better way to do this than using VCO-PLL combo (perhaps DDS or only VCO), keeping in mind that later I would like to switch to 0.5GHz to >6GHz by switching as little component as possible? 0.5Ghz - 3GHz is for prototype.
