Critical DAC Parameters for Multi-Carrier GSM/EDGE Transmitters


Abstract: The following article provides an insight of how the 260Msps, 14-bit digital-to-analog converter (DAC) MAX5195 with
LVPECL digital inputs fits into GSM/EDGE-based transceiver designs. The article details the exact SFDR, IMD, SNR and MTPR
requirements and how the MAX5195 high-dynamic performance
