CC1310: "txPower" in smartrf_settings.c, Is there are setting manual ？

Part Number: CC1310

Tool/software:

I want to change parameter "txPower" in smartrf_settings.c to decrease spurious.

At "SmartRF Studio 7", when Frequency setting is 315MHz, "txPower" in smartrf_settings.c  is 0x003f.

When I changed  this parameter to 0x0041 on Code Composer Studio, 315MHz and 945MHz are decreased.

When I changed  this parameter to 0x00c0 on Code Composer Studio, 315MHz, 630MHz and 945MHz are decreased more.

So, I want  setting manual of  "txPower" in smartrf_settings.c .

best regards.

    Hi,

    The PA table settings for 431-527 MHz are recommended for 315 MHz as well, so please use those as a starting point. 0x003F is the maximum PA gain setting for the PA. You should not need to find a new PA table.

    Section 10 of SWRA640 (CC13xx/CC26xx Hardware Configuration and PCB Design Considerations): https://www.ti.com/lit/swra640 discusses the PA table settings for the CC1310.

    Regards,
