The Development of Microwave Components for Earth Station Receiver

Historical aspects on the development of Microwave Integrated Circuits in Brazil

“…It is important to highlight that the funding received by the Laborat6rio de Microeletronica da 80s, there were several telecommunication companies responsible for the projects developed in the research centers and universities encompassed by the Brazilian Telecommunications Program. In the microwave field, some of these companies were: , the microwave research group from the Escola Politecnica, USP, presented an invited talk during the IEEE MTT-S Symposium in Los Angeles[5], where a large number of MIC components for Satellite Communications were described. Most of the circuits for Satellite Communications operated over the 3,7 to 4,2 GHz (down-link) and 5,9 to 6,4 GHz (up-link) frequency bands, and were manufactured with thin film microstrip lines on quartz substrate.III.…”
