For those of you interested in exotic Phase-lock Loop synthesizers, I just received this information from TI - http://e2e.ti.com/blogs_/b/analogwire/archive/2020/02/10/why-component-integration-carries-weight-for-space-based-pll-synthesizers The web page includes a link to an application note with more data on their highly integrated solutions enabling designs from 10MHz to 20GHz. The parts aren't cheap, but they are designed for space applications. I have no links with TI except for having used their devices for over half a century.

That's not extreme for this kind of part. The "engineering prototype part" (generally same die, just doesn't get the screening and paperwork) is only $3.5k in Q1. (you can also get an Eval board with the part for the same price) I wonder if the same part, without the space processing, is available?
