Direct Polar Radio Frequency Power (DPRFP) is a transmitter architecture where the carrier signal is synthesized using polar coordinates (amplitude and phase) rather than the traditional Cartesian method. This approach allows the use of highly efficient non-linear amplifiers, reducing power consumption and heat. It is particularly useful in wireless devices where battery life and thermal limits are strict constraints.

We switched to a DPRFP architecture for the new handset to hit our battery life targets on the LTE bands.
