When using an external RF front-end (refer to
may be required to adjust the startup time of the external PA relative to the internal building
blocks to optimize the overall PSD. This can be achieved using register bits PA_BUF_LT and
PA_LT.
Register 0x05 (PHY_TX_PWR):
This register controls the output power and the ramping of the transmitter.
• Bit [7:6] - PA_BUF_LT
These register bits control the enable lead time of the internal PA buffer relative to the enable
time of the internal PA. This time is further used to derive a control signal for an external RF
front-end to switch between receive and transmit, for details refer to
Table 9-2.
