Abstract
Techniques for power amplifier trimming based on coefficients for digital pre-distortion (DPD) are disclosed. In certain embodiments, a mobile device includes a transceiver including a first DPD circuit that digitally pre-distorts a first digital transmit signal, a second DPD circuit that digitally pre-distorts a second digital transmit signal, and a coefficient comparator circuit that generates a trimming control signal based on comparing a first plurality of coefficients of the first DPD circuit to a second plurality of coefficients of the second DPD circuit. The mobile device further includes a front end system including a first power amplifier that amplifies a first radio frequency (RF) signal from the transceiver, a second power amplifier that amplifies a second RF signal from the transceiver, and a power amplifier trimming circuit that controls trimming of at least one of the first power amplifier or the second power amplifier based on the trimming control signal.
