  • SYSTEMS AND METHODS PROVIDING ADAPTIVE POWER TRACKING
    Publication number: 20180124716
    Abstract: A radio frequency (RF) system including: a modem configured to generate a first set of digital bits and to create an analog RF signal from those digital bits; a power amplifier configured to receive the analog RF signal and to amplify the analog RF signal, the power amplifier including an input for a biasing voltage; a feedback loop configured to sample an output of the power amplifier, generate a second set of digital bits corresponding to the first set of digital bits, digitally process the second set of digital bits to determine a linearity characteristic of the power amplifier, and to adjust the biasing voltage in response to determining the linearity characteristic.
