Hi,
I'm working with a customer to add the CC2640 4x4 package to their design. We have followed the uTag Reference Design (www.ti.com/.../TIDC-CC2650-UTAG); however, there are some slight differences as they are using a 4-layer board and the AN043 PCB antenna. We have also referenced the CC26XX Design Guide, and reviewed the HW design checklist.
Before sending it for fabrication, we would like an expert set of eyes to review the layout and provide any suggestions.
Thanks in advance,
Mitchell
