    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)
    Conference report

    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 ...
  • 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
    Restricted access - publisher's policy
    A UHF outphasing transmitter, based on parallelcircuit Class E power amplifiers (PAs) and implementing a constant-gain envelope tracking strategy, is presented in this paper. Using the nonlinear model of the selected ...
