Restricted technologyBrazil belongs to a select group of countries capable of producing radiation tolerant chips, as well as equipment, satellites, missiles and spacecraft, within the same system.This technological leap has been guaranteed by the company Santa Maria Design House (SMDH), headquartered in Santa Maria-RS, according to an announcement of the National Council for Scientific and Technological Development (CNPq) of Brazil, through which the state has funded projects in this high-tech company.The Santa Maria Design House, coordinated by Professor Joćo Baptista Martins dos Santos, is the result of a competition launched in 2008 by the CNPq for financing development projects with integrated components (chips) for the Aerospace, Defence and Communications.Autonomous researchOne of the four released so far by the technology group is the radiation-tolerant circuit. According to the National Research Council, for this type of circuit is necessary to have a library of cells to radiation tolerant. Since neither the U.S. space agency (NASA) and European Space Agency (ESA) provide such libraries (because they are considered strategic for the countries that have them), the Brazilian company is planning to develop a library of cells tolerant to radiation in Brazil .In addition to radiation tolerant chips for use in satellites, spacecraft, or guided missiles, the Santa Maria Design House has also developed a radiation-tolerant electronic switch.INPE orderThis equipment was commissioned by the National Institute for Space Research (INPE) to ensure the proper functioning of the devices subject to the effects of electromagnetic radiation or cosmic, like the circuits on board satellites. The INPE is responsible for the satellites in Brazil that the country has developed, launched and operated in partnership with China.The Brazilian radiation-tolerant circuit will begin to be tested by SMDH the first quarter of 2012.According to the coordinator Martins, after several years away from areas of research and development, Brazil is redeeming the delay, because of their current economic situation and high rate of growth."More and more foreign companies coming to Brazil in search of partnerships and strategic projects. The Brazilian community can expect major advances in microelectronics, particularly in the field of electronics technology," said the entrepreneur SMDH.
