Claim 8:
9. A method of digital pre-distortion in a mobile device, the method comprising:
using a transmit circuit to generate a plurality of digital transmit signals, and to convert the plurality of digital transmit signals to a plurality of radio frequency signals;
in a first mode of the transmit circuit, providing digital pre-distortion to each of the plurality of digital transmit signals using a plurality of digital pre-distortion circuits of the transmit circuit;
generating a trimming control signal based on a plurality of coefficients of the plurality of digital pre-distortion circuits using a coefficient comparator of the transmit circuit;
amplifying the plurality of radio frequency signals using a plurality of power amplifiers; and
trimming the plurality of power amplifiers based on the trimming control signal using a power amplifier trimming circuit.
