This makes its response nonlinear, and therefore it is necessary to linearize it, in order to minimize the interference that nonlinearities cause outside the useful band (adjacent channel). The system used for this linearization occupies a high percentage of the hardware and software resources of the telecommunication equipment, so it is interesting to minimize its complexity in order to make it as simple as possible. This paper analyzes the differences between the laterally diffused MOSFET (LDMOS) and gallium nitride (GaN) power amplifiers, in terms of their nonlinearity graphs, and in terms of the greater or lesser difficulty of linearization. A correct choice of power amplifier will allow for minimization of the linearization system, greatly simplifying the complexity of the final design. info:eu-repo/grantAgreement/ES/MINECO-FEDER/TEC2015-65750-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.412 2019 ENGINEERING, ELECTRICAL & ELECTRONIC 125 / 265 = 0.472 2019 Q2 T2 0.303 2019 Electrical and Electronic Engineering 2019 Q2 Control and Systems Engineering 2019 Q3 Signal Processing 2019 Q3 Hardware and Architecture 2019 Q3 Computer Networks and Communications 2019 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Medrano Marqués, Nicolás Universidad de Zaragoza (orcid)0000-0002-5380-3013 5008 250 Universidad de Zaragoza Dpto.
