Hello,
Thanks! You might want to consider using this original PA from TI.com: http://focus.ti.com/docs/prod/folders/print/cc1190.html
I will be making a PCB for this, very very soon!
TI.com will be releasing their own PCB that includes CC1101 and CC1190 on-board in a few days (so they say), so you might want to wait for it. It will be 4-layers though, but I will be using just 2 layers for my version, and I will be using Johanson’s RF baluns designed for the CC1101.
Regards,
Muris
