The high power section of the TV-SAT-TDF-1 repeaters
Abstract
The high-power hardware for the repeaters of the German-French broadcast satellite TV-SAT/TDF-1 is described. The high-power section of the repeaters consists of FET driver amplifier, TWTAs, high-power isolator, high-power switch, output multiplexer, and RF harness. The repeater layout and resulting constraints for the bus concepts are derived based on the specific high-power features of the equipment. The relation between the electrical, mechanical, and thermal interfaces of the high-power equipment and the satellite structure, thermal control, and power conditioning is examined.
