All-electronic 100-GHz bandwidth digital-to-analog converter generating PAM signals up to 190-GBaud

We demonstrate an all-electronic digital-to-analog converter (DAC) with 100-GHz electrical bandwidth sampling at 240 GS/s, based on digital bandwidth interleaving. We test the DAC by generating up to 190-GBaud Nyquist shaped pulse amplitude modulated (PAM).
