DBS-Band Gen IV Klystron High Power Amplifier
for Satellite Communications
D BS- Band
The Gen IV High
Power Amplifier
Unmatched Efficiency
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.
New Features and Options
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.
Acoustically Quiet
The quietest K-HPA in the industry.
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.
Worldwide Support
Backed by over three decades of satellite
communications experience, and CPI's worldwide
24-hour customer support network that includes
fifteen 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.
