Adaptation of digital predistorter to linearize amplifiers using comparator
Jagla, Lukáš ; Ayöz, Suat (oponent) ; Götthans, Tomáš (vedoucí práce)
This master’s thesis presents a development of a new hardware implementing a comparator in the feedback path of DPD systems. A new architecture is proposed and selected features are verified by simulations. Subsequently, the suitable components are selected for high-speed performance and an acquisition module is proposed. A 4-layer PCB is well designed, manufactured, and prepared for further work. Afterwards, an appropriate firmware is developed for signal transmission and data acquisition. The obtained results serves for the evaluation of the proposed architecture and for its future implementation in real DPD systems.
