CC2652R: txPower settings

rei

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.
https://www.ti.com/lit/an/swra640e/swra640e.pdf

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,
Rei

Hi Luis,

Thank you very much. Will txpower be determined by evaluating many devices and considering variability?

Regards,

Hi Rei,

First off - we cannot guarantee the performance of your device if you choose to use your own txpower table. But, if that's what you want to do, I think this post answers your question. If your concern is variability, I'd repeat the measurements with multiple boards to ensure that it's a good match.
