요약5 billion People are connected to a wireless network through handheld devices, computers, and wearable devices. It is envisioned that the new generation millimeter-Wave (mm-Wave) network infrastructure will deliver multi-gigabit connectivity and enough channel capacity so that the user experience will be drastically improved, particularly in highly populated areas. In addition, future 5G and 6G enabled electronics that take advantage of the mm-Wave and sub-THz frequency spectrum will provide the technology necessary to achieve the full potential of the market opportunity in some consumer electronic areas, such as virtual/augmented reality, health care monitoring, and wearables. In addition, there are plenty of mission-critical Department of Defense (DoD) applications where mm-Wave and sub-THz hardware electronics are indispensable.New generation network infrastructure deployment targeted for 5G and 6G wireless communication is bringing new challenges to circuit and system designers that are yet to be addressed by conventional semiconductor technologies and circuit topologies. One of the main challenges is that battery energy density is not catching up to the power consumption needs of current electronic devices, particularly when the battery is constrained to a small form factor dictated by the size of consumer electronic. In addition, modern satellite constellations employ large transmitter arrays, which are exceptionally power hungry and rely on battery and solar cell power to operate. Moreover, network infrastructure such as cellphone towers and base stations, which are tethered to the lectical grid and do not have any battery constraints, often are extremely expensive to operate due to the high electricity and thermal management cost.Power amplifiers (PA) and transceiver (TRX) blocks are the most important components for any wireless data transmission system since they dictate the overall system efficiency, communication distance, bandwidth, and data rate. In addition, more than 80% of the energy in wireless systems is consumed by power amplifiers and this number will increase as newer network generations are being adopted. Therefore, for the nextgeneration networks (5G, 6G, and beyond) to be successfully deployed, new circuit design techniques and circuit/system topologies will need to be reimagined. The core of my research focuses on developing innovative system and block level architectures and design techniques that drastically increase the efficiency, linearity, and overall performance of PA/TRX blocks that will support next-generation mm-Wave/sub-THz wireless networks.First, we propose a cascadable self-similar high-order on-chip rat race hybrid coupler architecture that supports wideband operation by cancelling out the output phase imbalance and magnitude mismatch. Our proposed cascaded rat-race architecture can be further realized using a higher order implementation to extend the bandwidth of operation. Our cascaded rat-race mm-Wave implementations can support multi-band multi-standard 5G communication systems. This work was presented in the IEEE MTT-S International Microwave Symposium in 2018 [1].Secondly, by leveraging the block level co-design we implemented a wideband vector modulator phase shifter integrated with a power amplifier, pre-driver, and input/output Marchand balun covering a frequency range from 40GHz to 60GHz. In our proof-of-concept demonstration, the vector modulator provides a truly 0 magnitude and 40dB of dynamic range while covering 360째 of phase interpolation. The vector modulator is able to deliver sufficient output power to drive the next stage electronics.
