If PDM1 can be controlled then same circuit can be used for Dynamic bias control.
2. Step Bias Control and Dynamic Bias Control
(if controled PDM1)
The PDM1 output from the baseband IC can be used
to create a software-programmable voltage, to be used
at the phone designer’s discretion. To get high
efficiency and better ACPR, the phone designers can
change control voltage of the PA by adjusting PDM1
voltage according to output power of PA. A caution
when using this approach—careful consideration must
be made to to avoid an abrupt discontinuity in the
output signal when the step bias control voltage is
applied.
The figure below is an example of how to control the
PA for multiple bias points using the PA_ON and Vcntl
pin.
