Active Electronic Transceivers for THz Communication Systems

The presentation focuses on the design of analog transmit and receive frontends for THz wireless communication systems. The high-performance mm Wave monolithic integrated circuits, implemented in GaAs metamorphic high electron mobility transistor technologies with cutoff frequencies beyond 1 THz, integrate quadrature up and down conversion channels for either direct/zero IF or heterodyne architectures, LO frequency generation stages along with power amplifiers and low noise amplifiers operating at 240 and 300 GHz RF frequencies. On the system level, these transceiver components have enabled data transmission experiments with 64 Gbit/s bit rates over 850 m link distance and up to 100 Gbit/s over 15 m indoor distances, both, as pure electronic transmit and receive frontends, and in the prospective combination of photonic transmitters with electronic receivers.   Registration:   Where: Zoom session, link will be provided after the registration
