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.

Looks cool, except it uses USB2 which seems limiting in view of bandwidth.

480 Mbps is plenty for low GHz signals. 1GHz gives you 20MHz to play with, which turns into about ~100 Mbps max. A 6GHz signal pulling out all the stops will give you at ~1.6Gbps, but if you're dealing with data that extreme you're barking up the wrong tree with a cheap SDR like the HackRF.
