CC1120: Calculation for TX power did not match with the corresponding TX power value in Smart RF Studio.

Srinivasan S

Part Number: CC1120

Tool/software:

I just compere the TX power value to be set to PA_CFG2 register calculated by the formula provided in the CC1120 User guide with the corresponding TX power value showing on the Smart RF studio for the CC1120 module. Both did not match.

For +10 dbm, using the following formula I got 0x37 as the PA POWER RAMP value,. But in the Smart RF Studio it shows 0x34

Can you please give additional details for this.
