Are there any chips/modules currently being tested to add frequencies past sub-ghz? If not, we should see if something like rf explorers IOT modules would work to expand the spectrum analyzer range. They are kind big but might be worth checking out instead of starting with a bare chip.
There are no first-party radio modules for the Flipper Zero in the works at the moment, and no plans to start working on them, as that will be one of the main goals for the Flipper One (which will almost certainly have a full SDR inside)
