It indeed looks interesting and a little more integrated than the
current combination we have with the Wi2Wi and the Si4721.
And it adds 802.11a...
What I could not find is a complete datasheet
stating something about the dimensions of
the chip. And how easily we can connect the
antennas. The block diagram shows two
external "switches" whatever they are intended for.
Finally, we need some source to buy the chips. It
does not help to find the latest of the latest if we
can't get them in small quantities from a more or
less standard distributor.
We already have too many special chips with a
single source only and a single missing part is
stopping everything...
For the Wi2Wi we have at least 3 distributors
(even Mouser but they are a little expensive). And
for the Si4721 we can go back to the pin-compatible
Si4705 which is in stock with DigiKey...
So any ideas where to get Broadcom chips / samples /
data sheets?
BR,
Nikolaus

Hi Nikolaus
It might be possible to get an account - I have no idea - have you
tried to ask for one? Or ask for distributors in EU? Samples?:

Last summer, Broadcom suddenly and quietly reversed its anti-Linux
policies by releasing drivers for certain Broadcom wireless cards.
Most of the source code is closed, and at this point only a handful
of chipsets (mostly newer ones) are supported. But this development,
which has remained more or less under the radar, nonetheless has
important implications that extend well beyond the wireless scene.
