Abstract: A system includes: a host processor; a transceiver coupled to the host processor; and a power amplifier coupled to an output of the transceiver. The transceiver includes a transmit chain with digital pre-distortion (DPD) logic configured to: perform DPD correction operations on transmit data received by the transmit chain; and output corrected transmit data based on the performed DPD correction operations, wherein the output corrected transmit data is provided to the power amplifier.
