The function of the transmit bits is shown below:
Control bits TX<11:4> allow optimization of the transmit output stage. This allows variation of the decrease in
supply current with decreasing agc voltage and also allows optimization depending on output power and linearity
requirements. Figure 14 shows the variation of output stage supply current with agc voltage and the programmable
characteristics. The maximum current, agc threshold and slope can be programmed. The minimum current is not
programmable.
TX<11:10> (bits 15,14) allow the gain of the transmit output stage to be varied in 3 dB steps as shown in the table
below:
