TXPOWER

RADIO output power

Output power in number of dBm, i.e. if the value -20 is specified the output power will be set to -20 dBm.

When the radio is operated on high voltage (see VREQCTRL — Voltage request control for how to control voltage), the output power is increased by 3 dB. I.e. if the TXPOWER value is set to 0 dBm and high voltage is requested using VREQCTRL, the output power will be +3 dBm.
