The variable elements used in this paper are varactors. To verify its operation, it is applied to a process of matching a laser modulator in three different frequency bands for C-RAN (Cloud Radio Access Networks) applications. Experimental results demonstrate, as expected, that losses may depend on the state in which they are driven. Consequently, a state that can guarantee a good match could also imply greater losses, leading to a certain trade-off. The application of genetic algorithms in this context points out that it may be convenient to optimize the insertion losses of the complete chain instead of the return losses. info:eu-repo/grantAgreement/ES/DGA/T31-17R info:eu-repo/grantAgreement/ES/MICINN/RTI2018-095684-B-100 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.476 2021 COMPUTER SCIENCE, INFORMATION SYSTEMS 79 / 163 = 0.485 2021 Q2 T2 TELECOMMUNICATIONS 43 / 92 = 0.467 2021 Q2 T2 ENGINEERING, ELECTRICAL & ELECTRONIC 105 / 274 = 0.383 2021 Q2 T2 0.927 2021 Computer Science (miscellaneous) 2021 Q1 Engineering (miscellaneous) 2021 Q1 6.7 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Carro, PL Universidad de Zaragoza (orcid)0000-0001-5849-5198 Garcia-Ducar, P Universidad de Zaragoza (orcid)0000-0002-7452-446X Valdovinos, A Universidad de Zaragoza (orcid)0000-0003-2664-6339 5008 800 Universidad de Zaragoza Dpto.
