Is there SDR for the GHz range of signals used by modern equipment?

HackRF One can go up to 6GHz ($400 new or $100 on alibaba for a similar device). Any higher frequency than that you'll be paying thousands.

Yeah I dont know any SDR above 6GHZ but also other than mmwave 5G I also dont know much radio that is above 6Ghz in general

Quite a few radar systems are in the 8-10GHz range and satellite communications just above that. The general idea when using a SDR for these things is to have a separate frequency converter & amplifier at the antenna feed itself, then have an intermediate frequency <6GHz fed via cable to the SDR. Tends to be much easier and cheaper this way.
