DESCRIPTION AND EXPECTED PERFORMANCE OF FLIGHT-MODEL, 12-GIGAHERTZ, OUTPUT STAGE TUBE FOR THE COMMUNICATIONS TECHNOLOGY SATELLITE

摘要

This report describes the flight model output stage tube for the Communications Technology Satellite. The tube was manufactured by Litton Industries, Electron Tube Division, San Carlos, California. It is designated model L-5394; the flight tube serial number is 2022 R-l. The output stage tube is a 12-GHz, 200-W, coupled cavity traveling wave tube. The tube has a multistage depressed collector for efficiency enhancement. Collector cooling is accomplished by direct radiation to space. Expected rf performance and factors affecting on orbit perform¬ance and life are discussed.
