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. 000119662 536__ $$9info:eu-repo/grantAgreement/ES/DGA/T31-17R$$9info:eu-repo/grantAgreement/ES/MICINN/RTI2018-095684-B-100 000119662 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000119662 590__ $$a3.476$$b2021 000119662 591__ $$aCOMPUTER SCIENCE, INFORMATION SYSTEMS$$b79 / 163 = 0.485$$c2021$$dQ2$$eT2 000119662 591__ $$aTELECOMMUNICATIONS$$b43 / 92 = 0.467$$c2021$$dQ2$$eT2 000119662 591__ $$aENGINEERING, ELECTRICAL & ELECTRONIC$$b105 / 274 = 0.383$$c2021$$dQ2$$eT2 000119662 592__ $$a0.927$$b2021 000119662 593__ $$aComputer Science (miscellaneous)$$c2021$$dQ1 000119662 593__ $$aEngineering (miscellaneous)$$c2021$$dQ1 000119662 594__ $$a6.7$$b2021 000119662 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000119662 700__ $$0(orcid)0000-0001-5849-5198$$aCarro, PL$$uUniversidad de Zaragoza 000119662 700__ $$0(orcid)0000-0002-7452-446X$$aGarcia-Ducar, P$$uUniversidad de Zaragoza 000119662 700__ $$0(orcid)0000-0003-2664-6339$$aValdovinos, A$$uUniversidad de Zaragoza 000119662 7102_ $$15008$$2800$$aUniversidad de Zaragoza$$bDpto.
