Modulator and Demodulator Solutions for Real-Time Communication Toward 100 Gb/s: Realtime Modem Solution towards 100 Gb/s

Due to government and other agency regulations, microwave bands, which range in frequency from 6 to 42 GHz, often have a small bandwidth of a few hundred megahertz, which lowers the data rate for communications. On the other hand, high data rate communications can be realized in millimeter-wave (mm-Wave) frequencies (30–300 GHz). Tens of gigabits per second of bandwidth are available in mm-Wave bands, such as the D-band, from 110 to 170 GHz, and H-band, from 170 to 260 GHz [1] .
