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

"modern equipment" uses all KINDS of different frequencies, so that statement doesn't mean anything :/

Why not, if you want to address all those frequencies you need the highest capability, so GHz range not MHz range.

Not true at all.

FM wideband is something like 88-108MHz.

108-137MHz is a lot of aviation traffic.

7-144MHz lots of long range DX.

Then the 144-148 amateur band.

151-154 Multi Use Radio Service

433MHz has all kinds of sensor data from the world around you.

462-467 Family Radio Service (FRS) / General Mobile Radio Service (GMRS).

900MHz area has different types of beacons, cameras, etc.

1090 for Aviation beacon ADS-B

For other freqs you can often use an upconverter or downconverter to hit the freqs you need.
