Split main and predistortion signal paths with separate digital-to-analog converters for supporting digital predistortion in transmitters

Methods and apparatus for wireless communication using a transmitter capable of digital predistortion (DPD) and having a main signal path separated from a predistortion signal path, each path including a digital-to-analog converter (DAC). An example apparatus generally includes a main signal path comprising a first DAC, a power amplifier, and a combiner, the combiner being disposed in the main signal path between an output of the first DAC and an input of the power amplifier. The apparatus also includes a predistortion signal path comprising a second DAC, wherein the combiner is configured to combine a predistortion signal in the predistortion signal path with a main signal in the main signal path.
