We present in this article an up-to-date general and brief scan of the main research activities on RF and microwaves in Latin America. First, we geographically identify the main research and development clusters on RF and microwaves in this large region of the world. We next describe the most recent and representative research work developed in the most active Latin American countries in this technical field; namely, Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Mexico, Peru, and Puerto Rico. To develop this updated survey on RF and microwaves in Latin America, we started from considering previous similar reviews available in the literature [ ],[ ], including some of them focused on specific Latin American countries [ ],[ ]. In our review, we essentially focus on the last five or six years of scientific research production. Given the synergistic relationship between the IEEE MTT-S and the level of activities and maturity in RF and microwaves, we finalize our article by summarizing the status as well as the main challenges and opportunities for MTT-S in Latin America.ITESO, A.C.
