DEVELOPMENT AND PERFORMANCE OF POWER PROCESSOR SYSTEM FOR 12-GIGAHERTZ, 200-WATT AMPLIFIER FOR COMMUNICATIONS TECHNOLOGY SATELLITE

摘要

This report describes the electrical and environmental requirements for a power processor system (PPS) designed to supply the appropriate voltages and currents to a 200-watt traveling wave tube (TWT) for a communication technology satellite. A block diagram of the PPS, the interface requirements between the PPS and spacecraft, the interface requirements between the PPS and 200-watt TWT, and the environmental requirements of the PPS are presented. Also included are discussions of protection circuits, interlocking sequences, and transient require¬ments. Predictions of the flight performance, based on ground test data, are provided.
