A concurrent dual-band uneven GaN Doherty power amplifier (PA) for two wide-spacing
frequencies application is proposed in this paper. To avoid an early load modulation-drop …

A method for the parameter extraction of a nonlinear-dynamical behavioral model is
considered. At this method, the model satisfactorily reflects the nonlinear signal distortions …

In modern communication systems, nonlinearity in power amplifiers (PAs) and in-phase and
quadrature-phase (I/Q) imperfections in the transmitter are of enormous concern. With the …

In this paper, a joint predistorter based on the multi-variable memory polynomial (MP) model
is proposed to compensate for the modulator in-phase/quadrature (I/Q) imbalance, the …

The nonlinear behavior of power amplifiers (PAs) and the in‐phase/quadrature (I/Q)
imbalance in I/Q modulators are considered as the main sources of distortions and …

There is an ever increasing need for enabling higher data rates in modern communication
systems which brings new challenges in terms of the power consumption and nonlinearity of …

This thesis investigates and proposes new models for the digital compensation of radio
frequency (RF) imperfections in broadband wireless transmitters, more specifically for non …
