Russia installed a radio-jammer that interferes with the signals that direct GPS-guided munitions. Last week, Ukraine blew it up ... with a GPS-guided bomb.
A jammer will be a high output RF. The jammers just shout louder than the signals they want to jam to drown them out. This is wideband high gain noise that degrades the signal to noise ratio of the target signals.
I think the main point is that it’s technically possible to target jammers of any sort based on following the jamming signal itself, but the question is if there are any weapons that do that for arbitrary frequency ranges or if that is currently limited to radar frequencies.
The unsettling part is it doesn’t have to be a jamming signal that is targeted. It’s possible to have a missile target areas with higher 3G activity or even follow a wifi signal to a device, though it would need another method of getting within range. But targeting a signal is easier than communicating with that signal, plus a missile could have a much better receiver than your phone or router.

Close, but you’re missing the part that RF spectrum is more than just wideband. There’s X band, UHF, UWB, and many many more.
Jammers pick a portion, or portions, of the RF spectrum, and blast it with noise, yes.
But they don’t magically deny every bit all at once.
And radar is different still, especially when you’re talking about SEAD, or radar hunting missiles.
