CONFIG_MPSL_FEM_NRF21540_TX_GAIN_DB_POUTB

TX gain value (POUTB)

Type: int

Help

The default value of 10 dB is based on nRF21540 Product Specification (v1.0) and it
corresponds to the configuration in which the pin MODE=1 and register POUTB_SEL=0.

Alternatively, if register POUTB_SEL=1, FEM will use TX gain value defined by the UICR.
In that case user must set value of this Kconfig option to match UICR content.
