Fractional-N PLL based transmitter
6.4.1
Power amplifier modes
The bits PAM0 and PAM1 located in the special function register TXCON can be used to
choose between three regulated and one unregulated power modes. The regulated
modes should be used for applications where the output power should be independent
from changes of the supply voltage and ambient temperature.
Table 8.
Bit 7
For very high power applications the regulation mechanisms can be deactivated by using
power mode 3 (see Table 6)
The best regulation characteristics are provided using the lowest power mode so the
lowest acceptable power mode for the application should be selected and the exact output
power controlled by means of the control signals ACON0, ACON1 and ACON2.
Table 9.
PAM1
[1]
The lowest supply voltage and temperature dependency is achievable with power mode 0.
