      This paper proposes a novel three-dimensional digital predistorter (3D-DPD) suitable for compensating nonlinear distortion in dual-band (DB) envelope tracking (ET) power amplifiers (PAs). By taking into account the ...
    • A low-complexity memoryless model for envelope tracking RF power amplifiers 

      Montoro López, Gabriel; Gilabert Pinal, Pere Lluís; García García, José Ángel; Ruiz Lavin, Maria de las nieves; Marante, Reinel (European Microwave Association (EuMA), 2014)

      This paper presents a new kind of behavioral model structure for characterizing static nonlinearities in dynamically supplied RF power amplifiers. The proposed architecture is based on the combination of several basic cells ...
    • Comparison of model order reduction techniques for digital predistortion of power amplifiers 

      Gilabert Pinal, Pere Lluís; Montoro López, Gabriel; Wang, Teng; Ruiz, Nieves; García García, José Ángel (Institute of Electrical and Electronics Engineers (IEEE), 2016)
      Conference report
      Open Access
      This paper compares and discusses four techniques for model order reduction based on compressed sensing (CS), less relevant basis removal (LRBR), principal component analysis (PCA) and partial least squares (PLS). CS and ...
    • Digital predistorters go multidimensional: DPD for concurrent multiband envelope tracking and outphasing power amplifiers 

      Gilabert Pinal, Pere Lluís; Montoro López, Gabriel; Vegas Garcia, Ángel; Ruiz Lavin, Maria de las Nieves; García García, José Ángel (2019-05-01)
      Article
      Open Access
      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 ...
    • Seguimiento de la envolvente con ganancia constante mediante esquema outphasing en tecnología GaN HEMT 

      Benito, Adán L.; Ruiz, María Nieves; García García, José Ángel; Gilabert Pinal, Pere Lluís; Montoro López, Gabriel (Unión Científica Internacional de Radio (URSI), 2015)
      Conference report
