CC2652R: txPower settings

Genius 5285 points
Part Number: CC2652R

Hi,

My customers are developping a product using CC2652R and Single-end circuit.
I understand that CC2652R has not been evaluated for single-end. Therefore, SmartRF Studio cannot set the correct txPower.

Customesr want to evaluate the single-end circuit and determine the txPower table. So we looked at the documentation and found the following description.

10 PA Table
"The txpower values used in the table are selected to provide as low as possible device to device variation."

We are finding it difficult to determine txPower by only evaluatings.
Could you tell me how to decide txPower to reduce device variability?

Regards,
