the PCB is custom made from an italian company, I could try to ask
them if they still exists, but it's very difficult that they release
any info about it anyway.
The RF switch is there to software select one of two antennas,
probably for redundancy, given the particular application for which it
has been made.

I already seen this site, but there's no component level datasheet, on
my board only the two rockwell chips have been used, and probably in a
custom design.
