Hi,
So i'm trying to use the cc8531 and i was using the typicall circuit and i have a doubt:
You give a LNA as an alternative for the matching filtering, but the small circuit that appears in the design (see picture) 
doesn't have any value or reference, so i would like to get them.
The other question is: If i use or the LNA or the circuit you propose, am i gonna get the same results or you recommend something in particular?
And the last one is: Can the LNA (cc2590) work in a two layer board or it has to be 4 layered as you suggest in the datasheet?
Thank you so much for your help :)
