Cheapest and simple IC combination for 4..6GHz divide-by-1xxx prescaler?

[Terminator3]

For example, ADF4107 is used here: https://www.qsl.net/bg1ceo/Tech_topic/rf/7G_prescaler/prescaler.html
is it an optimal solution? I googled some solutions, but they focus on 1000 division factor. I do not need an exact by-1000 division, something around it will be great. So i guess there may be possible better solution.

You can combine these prescaler, for example using two series HMC394LP4, you can get 32*32 times divide by
