Resumo: | Abstract: The linearization of power amplifiers in RF used in the transmission of analog and digital signals is one of the segments that has evolved considerably in recent years. Keep adjacent channels with low spurious constituted by harmonic distortion and the intermodulation products is one of the great challenges of electronic engineering applied to telecommunications. Spurious signals are from the intrinsic nonlinearity in any semiconductor device excited by large signs. Various techniques have been used, but the combination of the pre-distortion with direct feed (feed-forward) is quite promising. Whereas more stringent specifications are imposed by regulators for the transmission of digital TV, the design of power amplifiers effectively linearized will be one of the major obstacles to be overcome by the designers in our country. This work presents a comparative study of the various linearization techniques based on numerical simulations supported by the software "Advanced Design System", Agilent Technologies and programs developed in Matlab. It is shown that the combination of techniques, pre-distortion and direct power, offers a promising alternative to implement linearizadores high efficiency. The work also contributes derived mathematical models of the basic theme of these two linearization techniques which are suitable for its numerical simulation |

Manter canais adjacentes com baixo n?vel de esp?rios constitu?dos pela distor??o harm?nica e pelos produtos de intermodula??o ? um dos grandes desafios da engenharia eletr?nica aplicada ?s telecomunica??es. Esp?rios s?o sinais decorrentes das n?o-linearidades intr?nsecas em qualquer dispositivo semicondutor excitado por grandes sinais. Diversas t?cnicas t?m sido utilizadas, mas a combina??o da pr?-distor??o com a alimenta??o direta (feed-forward) ? bastante promissora. Considerando que especifica??es mais rigorosas ser?o impostas pelos ?rg?os reguladores para a transmiss?o de TV digital, o projeto dos amplificadores de pot?ncia efetivamente linearizados ser? um dos grandes obst?culos a ser superado pelos projetistas em nosso pa?s. Esse trabalho apresenta um estudo comparativo entre as diversas t?cnicas de lineariza??o baseado em simula??es num?ricas apoiadas pelo software "Advanced Design System", da Agilent Technologies e em programas elaborados no Matlab. ? mostrado que a associa??o das t?cnicas, pr?-distor??o e alimenta??o direta, oferece uma promissora alternativa para implementar linearizadores de elevada efici?ncia. O trabalho tamb?m contribui com modelos matem?ticos extra?dos do tema b?sico destas duas t?cnicas de lineariza??o e que s?o adequadas para sua simula??o num?ricaSubmitted by Tede Dspace (tede@inatel.br) on 2016-09-28T17:52:00Z No. of bitstreams: 2 license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5) Disserta??o mestrado Cristian.pdf: 2680209 bytes, checksum: da4a3ca1ef2d77381bc2cca46c690b4c (MD5)Made available in DSpace on 2016-09-28T17:52:00Z (GMT).
