Hi

The price of the spin isn’t just the cost of the masks. There’s a non-trivial cost involved in the redesign of the chip and the testing that finds the problem. 

You can indeed do a project run for $5,000 and get usable chips. The same process moved to a single wafer also can give you a few thousand (maybe) of some very expensive dice. If you want a proper mask set and high volume / low cost tooling - it’s not cheap.

The issue after that probably is that you really want the version 3 (or 9) chips that actually work with all the modulation schemes. I’ve been down the road with a number of similar chips that took *many* rev’s before they really did what they were intended to do. Many millions of dollars a pass times 3 or 6 passes is an whole different world …..

I've been given to understand that an RF ASIC spin in CMOS (which works up to low microwave frequencies) is around $100k and would get you a wafer of dice.
