Hi,
as far as I can see the only thing on wbx board that has adjustable
feature in rx path is attenuator, everything else has fixed gain. Am I
missing something here?
Best and thanks,
Nemanja
The way variable gain is nearly-universally implemented in RF systems is
with an attenuator in the RF path. So, that 31.5dB variable attenuator
*is* the variable gain.
