Aspects disclosed herein relate to predicting one or more signal characteristics to improve efficiency for a PA. A wireless communications device may be include a power amplifier and a processor that is associated with a signal prediction module. In an aspect, the processor may be a modem, a RF chip, etc. In one example, the wireless communications device may be configured to buffer one or more values associated with an input signal. The signal prediction module may be configured to predict a system response to at least a portion of the one or more buffered values, and generate a switcher control signal based on the system response. The signal prediction module may also generate a predicted supply voltage from the values associated with the input signal. |
