Abstract Details

2018, Doctor of Philosophy, Ohio State University, Electrical and Computer Engineering.
The growth of cellular and wireless communications over the last two decades has led to unprecedented congestion of the radio frequency (RF) spectrum. New frequency bands and bandwidth allocations are constantly being opened up to alleviate this congestion, but the demand for wireless data is increasing faster than spectrum availability. Despite fundamental hardware limitations, the complex and rapidly changing wireless environment necessitates three key requirements for RF transmitter: frequency-agility, capability of transmitting complex modulation schemes, and power efficiency. In this work, a four-way outphasing architecture is developed for the generation of complex modulated waveforms across a wide RF frequency range. This proposed architecture offers an ACLR improvement equivalent to a 2-bit phase resolution increase compared to traditional two-way outphasing architectures. In addition, this architecture is more resilient to PA amplitude and timing mismatch. This architecture is implemented in DARPA's Diverse Accessible Heterogeneous Integration (DAHI) process technology, featuring the heterogeneous integration of 45nm CMOS SOI and 0.2 μm GaN process technologies. The fabricated transmitter achieves greater than 33 dBm output power and a peak transmitter efficiency of greater than 41%.
