Product data sheet
Table 14:
The register selects the cut-off frequency of the RX baseband filter. The cut-off frequency can be set
from 5 MHz to 36 MHz in 32 steps of 1 MHz
[1]
Table 15:
These bits control the additional gain of the baseband between 0 dB and 9dB
[1]
Table 16:
This bit controls the RF attenuation inside the LNA amplifier.
