ChinaSat-7

ChinaSat 7 or ZX 7 (Zhongxing 7) is a Hughes HS-376 model geostationary telecommunications satellite built for the China Telecommunications Broadcast Satellite Corporation (ChinaSat). It was the first satellite ChinaSat had ordered from a western spacecraft contractor, Hughes Space and Communications International, Inc., known today as Boeing Satellite Systems International, Inc. ChinaSat 7 was built to carry voice, fax, data, television signals, and other communications services across China and portions of Southeast Asia for ChinaSat, which is a division of China's Ministry of Post and Telecommunications. The spacecraft was manufactured at the Hughes Space and Communications Company facilities in El Segundo, Calif. ChinaSat 7 carried 24 active transponders (with six spares) operating in the C-band (6/4 GHz) and extended C-band (3.6 GHz) frequency range, powered by 16-watt traveling-wave tube amplifiers. Four channels had 72 MHz of bandwidth each, and the remaining 20 had 36 MHz capacity each. Radiated power over China was to have averaged 37 dBW.
