15.15 Output Power Programming
The RF output power level from the device has
two levels of programmability, as illustrated in
Figure 51. Firstly, the PA_TABLE7-
PA_TABLE0 registers can hold up to eight user
selected output power settings. Secondly, the
3-bit FREND0.PA_POWER value selects which
PA_TABLE7-0 register to use. This two-level
functionality provides flexible PA power ramp
up and ramp down at the start and end of
transmission. In each case, all the PA power
settings from PA_TABLE from index 0 up to the
FREND0.PA_POWER value are used.
The power ramping at the start and at the end
of a packet can be turned off by setting
FREND0.PA_POWER to zero and then
programming the desired output power in
PA_TABLE0.
Table 67 contains recommended PA_TABLE
settings for various output levels and
frequency bands, together with current
consumption in the RF transceiver.
PA_TABLE7[7:0]
PA_TABLE6[7:0]
PA_TABLE5[7:0]
PA_TABLE4[7:0]
PA_TABLE3[7:0]
PA_TABLE2[7:0]
PA_TABLE1[7:0]
PA_TABLE0[7:0]
The PA uses
this setting.
Settings 0 to PA_POWER are used
during ramp-up at start of transmission
and ramp-down at end of transmission,
and for OOK modulation.

The SmartRF® Studio software
e.g 6 should be used to get optimum
PA_POWER[2:0]
in FREND0 register
PATABLE settings for various
output powers.
