Operation in the mm-wave and terahertz (THz) bands has gained great interest due to abundance of unutilized spectrum and resurgence of new applications in wireless/cellular communications, most notably 5G. If combined with spectrally efficient (de-)modulation techniques, mm-wave/THz wireless communication has the potential to achieve multi-gigabit-per-second wireless data-rate. In addition, the operation at higher frequency gives rise to smaller size passive components (most notably antennae), making it possible to design and implement massive phase-array or MIMO systems on a single die or single wafer. As the communication schemes including spectrally-efficient (de-)modulation and carrier aggregation techniques are making progress at RF frequencies, far more challenging requirements will be imposed on the oscillator and frequency synthesis design. Increasing the carrier frequency towards the mm-wave/terahertz regime only makes these requirements more stringent.

These seminar series cover two generic inter-related themes, namely (1) a comprehensive overview of mm-wave multi-antenna transceiver architectures which includes phased-array, MIMO, and beam-forming MIMO architectures; (2) a general, yet in depth, overview of frequency generation, synthesis, and high-efficiency radiation at mm-wave and sub-terahertz frequencies.
