RF Power Amplifier Characterization for Predistortion Linearization

The purpose of this Major Qualifying Project was to develop and evaluate a digital baseband predistortion approach for radio frequency power amplifiers (RFPA). We also aimed to develop a hardware implementation of the system. The predistorter implements a look-up-table (LUT) to restore a baseband signal constellation and is simulated using actual RFPA characteristics. The testing includes the use of MATLAB, a Xilinx Spartan-3 FPGA as a pattern generator, a digital-to-analog converter (DAC), a modulator, an RFPA, and a demodulator
