Efficiency enhancement by reconfigurable matching networks in LINC transmitters 2017 Access copy available to the general public Unrestricted This paper proposes the use of a transmitter based on a linear amplification with nonlinear components (LINC) architecture, in which the reconfigurable matching networks (RMNs) are included. By varying the RMN active cell number, it is possible to change the load impedance at the power amplifier (PA) output, improving the amplifier drain efficiency and therefore the efficiency of the whole system. A long-term evolution (LTE) downlink signal with a bandwidth of 1.4 MHz and a peak-to-average power ratio (PAPR) of 11.48 dB is applied in order to carry out the experiments. Results show that the use of the RMNs in a LINC architecture improves the efficiency at all tested frequencies, especially at 927 MHz reaching an enhancement of 36.50%. Regarding the distortion, the adjacent channel leakage ratio (ACLR) values increase in all cases, with an improvement of 3.5 dB at 958 MHz. Finally, in terms of error vector magnitude (EVM), the proposed architecture offers a value of 1.96% at 927 MHz. info:eu-repo/grantAgreement/ES/DGA/GCM-T97 info:eu-repo/grantAgreement/ES/MINECO/TEC2014-58341-C4-2-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.407 2017 TELECOMMUNICATIONS 35 / 87 = 0.402 2017 Q2 T2 ENGINEERING, ELECTRICAL & ELECTRONIC 98 / 260 = 0.377 2017 Q2 T2 0.301 2017 Computer Networks and Communications 2017 Q2 Signal Processing 2017 Q3 Computer Science Applications 2017 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0001-5849-5198 Carro, P.L.
