Hello, Can you verify the tuning Componets for the LP-EM-CC2340R5 EVM?

This Schematic differs from BOM:. Z60 = Z62 = No POP, Z61 = 0 Ohm.

So L33 2.8nH (Q14) and C33, C34 = 1.5 pF, CA1 is also part of this at 15pF. Is this correct?

Hi,

Where did you download the design files you are using? The BOM and the schematic match when downloaded from its official public release at:

https://www.ti.com/tool/LP-EM-CC2340R5#design-files

CA1 and CA2 share one pad and are designed to select only one RF path - either the embedded antenna ANT1 or the SMA connector J7. This allows the board to be tested in either irradiated or conducted modes.

Hope this helps,

Rafael
