S-Band Gen IV Klystron High Power Amplifier for Satellite,Troposcatter and Terrestrial Gapfiller Applications S- Band The Gen IV High Power Amplifier (K4S74 and K4S71 Series) Unmatched Efficiency S-Band Gen IV — provides up to 1.2, 2.5 or 3.0 kW of power in a dual drawer package Uses less power and produces less heat than any other K-HPA. Features Power Saver and Power Tracker, optimizing K-HPA efficiency to meet your operating condition. Scopescreen provides a graphical log display. The Ethernet Option provides higher speed connections, can update and coordinate all clock settings, and enables a snapshot feature where user can create a file containing all settings, alarms and faults at a single point in time. Integrated Protection Switching Unmatched Size Greater efficiency and exceptional thermal margins have enabled CPI to design the smallest KPA on the market --- without the threat of overheating or a shorter klystron life. Easy Maintenance All areas of the amplifier are easily accessible and there are no large harnesses to get in the way. Separate RF and Power Supply drawers slide out from a standard rack. Greater Reliability Low temperatures are the key to longer lifetimes for klystrons and electronic parts. The CPI power supply design and high efficiency, multi-stage depressed collector klystron make these lower temperatures possible. Useful Displays Large, high quality, color, graphical display has a wide viewing angle and a sharp appearance. All important functions are clearly displayed, and an event log is included. Acoustically Quiet The quietest K-HPA in the industry. Worldwide Support Backed by over three decades of satellite communications experience, and CPI's worldwide 24-hour customer support network that includes sixteen regional factory service centers. 811 Hansen Way P.O.
