C-Band Gen IV Klystron High Power Amplifier for Satellite Communications C - Band The Gen IV High Power Amplifier Unmatched Efficiency C-Band Gen IV — provides up to 3.35 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. 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. 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. 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. 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. Useful Displays Large, high quality, color, graphical display has a wide viewing angle and asharp appearance. All important functions are clearly displayed, and an event log is included. Integrated Protection Switching Redundant switch controller eliminates the cost of external controllers. System status is shown on the display and switch controls are implemented locally on the front panel touch-pad, or remotely via the digital serial interface. 811 Hansen Way P.O.

Excess imbalance may cause an increase in residual RF noise (AM, FM and PM). Phase noise increase is typically 2.5 dB / % imbalance. 3 AC current harmonic content: less than 20%, primarily fifth and seventh harmonics. Harmonics must be considered when choosing UPS sources. 4 Lower power consumption can be achieved if power saver (included as standard) is employed when operating below rated output power.
