The Federal Communications Commission has recognized that broadband access is a critical infrastructure and a foundational necessity for “economic growth, job creation, global competitiveness, and a better way of life.” While the spectrum available above 24 GHz presents opportunities to address the future demand for wireless infrastructure, exploiting these higher frequency bands requires strategies to realize small, low-cost, broad bandwidth, low power hardware. Although significant research effort over the past decade has focused on low-cost single-chip CMOS transceivers above 24 GHz, these devices have yet to experience the same widespread adoption as similar integrated transceivers operating in the lower frequency commercial bands (1-5 GHz), due in part to the increased complexity and power consumption of mmWave transceivers. The proposed research seeks to transform existing high-frequency transceiver hardware solutions by introducing several circuit and chip-level architectural techniques to integrate low power, broad bandwidth, and longer range beamforming transceivers in silicon CMOS technologies. These techniques will also have significant impact on other applications, including radar and imaging systems. Moreover, these system and circuit challenges provide an ideal backdrop to integrate much of this research with classes, preparing students for careers in industry and academia.
