| Byte Index | Field Name | Bits | Bit Field Name | Type | Description |
|---|---|---|---|---|---|
| 0–1 | commandNo | W | The command ID number | ||
| 2–3 | Reserved | ||||
| 4–7 | txPower | 0–6 | IB | W | New TX power setting. TI recommends using values from the SmartRF Studio. Value to write to the PA power control field at 25°C. See Equation 14 for details. |
| 6–7 | ibBoost | W | Value to write to the bias control field of the PA | ||
| 8 | boost | W | Driver strength into the PA 0: Low driver strength 1: High driver strength | ||
| 9-15 | tempCoeff | W | Temperature coefficient for IB 0: No temperature compensation | ||
| 16–21 | paLdoTrim | W | Value to write to the output voltage control of the 20 dBm PA LDO | ||

On reception, the radio CPU will set the transmit power and temperature coefficient for the 20 dBm PA for use the next time transmission is started. If a packet is being transmitted, the transmit power will not be updated until transmission starts for the next packet.
Each time transmission of a packet begins, temperature compensation of the transmit power is done.
It is not allowed to use CMD_SET_TX20_POWER if the 20 dBm PA was not configured in the radio setup command; in this case, CMD_SET_TX_POWER (see Section 26.3.3.2.16) should be used.
The radio CPU returns DONE in CMDSTA when finished.
