Event Description

Wireless communication is undergoing a fundamental transformation as the new spectrum in the millimeter-wave (mm-Wave) frequencies (30-300 GHz) opens up to serve as the backbone for the next-generation wireless infrastructure. The application range is expected to be extremely heterogeneous ranging from extremely high-speed cellular connectivity, automotive-to-anything (V2x), augmented reality (AR), virtual reality (VR) to wireless backhaul and last mile connectivity. As multiple spectral regions across 20-100 GHz become available, it will be essential to move from current frequency-specific designs that operate at known frequencies to dynamically spectrally-adaptive architectures that learn from the available spectral information.

At the hardware level, such reconfigurability is hugely challenging to achieve in the mm-Wave transceiver. Mainly, for the transmitter (Tx) architecture, there is a substantial trade-off between output power, energy efficiency, spectral reconfigurability and spectral efficiency (linearity). This thesis presents a generalized multi-port network synthesis approach to break these trade-offs in an mm-Wave power amplifier (PA) architecture for reconfigurable transmitter front-ends.
