Electronics, 2023 We demonstrate in this work effective linearization on a millimeter-wave (mm-Wave) broadband monolithic gallium nitride (GaN) power amplifier (PA) using digital predistortion (DPD). The PA used is a two-stage common-source (CS)/2-stack PA that operates in the mm-Wave 5G FR2 band, and it is linearized with the generalized memory polynomial (GMP) DPD and

Digital Predistortion (DPD) Algorithm For 5G Applications [PDF]
, 2021 Abstract The wireless networks of upcoming fifth generation (5G) promises connection speeds and data rates that are one hundred times faster than the existing networks and much improved signal and connection quality. As there is the development of wireless communication systems, the requirement of Power Amplifier’s linearity is hard.

Digital Predistorters Go Multidimensional: DPD for Concurrent Multiband Envelope Tracking and Outphasing Power Amplifiers [PDF]
IEEE Microwave Magazine, 2019 Over at least the last two decades, digital predistortion (DPD) has become the most common and widespread solution to cope with the power amplifier's (PA's) inherent linearity-versus-efficiency tradeoff. When compared with other linearization techniques, such as Cartesian feedback or feedforward, DPD has proven able to adapt to the always-growing ...
