Function
Used to setup the voltage provided by the PA_BIAS AMPLIFIER to deter-
mine the BIAS VOLTAGE to provide to the PA when the desired output
power is MID_POWER. The MID_BIAS selection will select a V
OUT
on
PBIAS between 1.6V and 2.6V.
User selectable desired output power at antenna. The 5 MSB’s are integer
portion in dBm. The LSB is 0.5dBm. Example: +19.5dBm is represented by
100111.
User programmable offset to adjust to process/board variations in the
power control loop. This is a 2’s-complement value with the LSB equal to
0.5dB.
User programmable delay to allow a single TX_PE line to be used to enable
the BBP and the radio function. Programmable in 0.5us increments from
0us to 3.5us.

User programmable MAX output power provided when PABIAS=2.6V. This
allows the power control function to be customized for various PA’s. The 5
MSB’s are integer portion in dBm. The LSB is 0.5dBm.
User programmable MAX output power provided when
PABIAS=MID_BIAS. This allows the power control function to be custom-
ized for various PA’s. The 5 MSB’s are integer portion in dBm. The LSB is
0.5dBm.
User programmable MAX output power provided when PABIAS=1.6V. This
allows the power control function to be customized for various PA’s. The 5
