Summary:A system for calibrating a power amplifier (PA) includes a memory, a processor, a digital pre-distorter (DPD), and a data converter. The DPD includes a programming interface module, a pattern generator, a multiplier, and a pre-distorter module. The multiplier multiplies reference baseband stream data from the memory with pattern coefficient data generated by the pattern generator to generate shaped reference baseband stream data. The pre-distorter module generates pre-distorted shaped reference baseband stream data. The PA receives a low-power reference radio frequency (RF) signal corresponding to the pre-distorted shaped reference baseband stream data and generates a high-power reference RF signal. The processor receives and compares the pre-distorted shaped reference baseband stream data with amplified shaped reference baseband stream data corresponding to the high-power reference RF signal, and adjusts pre-distortion parameters in the pre-distorter module based on the comparison such that the PA generates a linear high-power RF signal.
