FPGA SerDes capability as switch mode PA modulator

This paper demonstrates the ability of current commercially available FPGA hardware to generate radio frequency pulsed modulated signals. This work is carried out to determine the suitability of integrated SerDes devices for use in frequency flexible transmitters capable of modulating switch mode power amplifiers (SMPA´s). The paper shows that it is possible to meet spectral mask requirements of -50dBc for WCDMA signals at carrier frequencies in digital dividend from 750MHz to 1GHz.
