Over 40-Gbps wireless communication in the D-band is described. 120-GHz-band transmitter and receiver modules employing direct modulation architecture are developed using 70-nm mHEMT technology for a RF amplifier and 0.1-μm pHEMT technology for an IQ modulator and a frequency doubler. The developed modules successfully demonstrate 64QAM transmission with a data rate of 42 Gbit/s occupying a bandwidth of less than 10 GHz (spectrum efficiency of 4.92 bit/s/Hz) and a BER of less than 10−3. The feasibility of 60 Gbps wireless transmission is also verified. To the best of our knowledge, this is the first time that over 40-Gbps D-band communication using a practical bandwidth of less than 10 GHz is achieved.
