Abstract :
This paper describes a S-Band Transmitter (TX) for the Technological Satellite (SATEC) using commercial SMD components emphasizing the designs concepts and tests results. The S-Band TX was designed to transmit GPS (Global Positioning System) data on BPSK format, modulated at 2.2044 GHz. The Transmitter was fully tested at INPE facilities within spatial requirements for flight qualifying. The tests results presented give the good performance of the equipment.
