A Doherty Power Amplifier with Extended Bandwidth and Reconfigurable Back-off Level
(University of Waterloo, 2013-03-22)Emerging wireless standards are designed to be spectrally efficient to address the high cost of licensing wireless spectra. Unfortunately, the resulting signals have a high peak-to-average ratio that reduces the base station ... -
A Novel Power-Scalable Wideband Power Amplifier Linearization Technique
(University of Waterloo, 2019-08-29)Global mobile traffic is expected to continue to increase at an astonishing rate in the future, due to the ever-increasing number of mobile phone subscribers and the adoption of smart devices which generate significantly ... -
Push-Pull Based High Efficiency and High Power Broadband Power Amplifiers for Wireless Base Stations
(University of Waterloo, 2019-03-11)The monthly data throughput by 2021 is forecasted to be ten times that of December 2015. As a result of the on going dramatic increase in demand, service providers are assigned new frequency bands to accommodate more ... -
Real-Time FPGA-Based Testbed for Evaluating Digital Predistortion in Fully Digital MIMO Transmitters
(University of Waterloo, 2023-04-27)As one of the key enabling technologies of 5G networks, massive multiple-input, multiple-output (MIMO) transmitters use many transmit chains to ensure a very high data rate and acceptable signal quality. Realizing Massive ... -
Single Input Single Output Digital Pre-Distortion at Millimeter Wave Frequencies for Phased Arrays
(University of Waterloo, 2019-08-30)The limiting fact that is impeding the increase in data rate in the current generation of wireless communication is the limited available spectrum in the sub-6 GHz bands. This has motivated the shift to higher frequencies ...
