Abstract :
This paper presents a mixed-signal behavioral simulation for an RF power amplifier predistortion system. The predistortion architecture is based on FPGA-based look-up tables that drive RF vector modulators. Behavioral models are extracted from the RF components and simulated in the same file with the digital components. Trade-offs are made between the FPGA design and the RF component design to optimize the performance of the system.
