VZU-6995AY
500W Compact High Power Amplifier
for Satellite Communications
DBS-Band
The VZU-6995AY
DBS-Band
500 Watt TWT High
Power Amplifier—
high efficiency in a
compact package.
Easy to Maintain
Provides 500 watts of power in a 5 rack unit
package, digital ready, for wideband, single- and
multi-carrier satellite service in the 17.3-18.4 GHz
frequency band. Ideal for transportable and fixed
earth station applications where space and prime
power are at a premium.
Modular design and built-in fault diagnostic
capability with convenient and clearly visible
indicators for easy maintainability in the field.
Efficient
Employs a high efficiency dual-depressed
collector helix traveling wave tube backed by
many years of field-proven experience in
airborne and military applications.
Worldwide Support
Backed by over three decades of satellite
communications experience, and CPI’s worldwide
24-hour customer support network that includes
twenty regional factory service centers.
Simple to Operate
User-friendly microprocessor-controlled
logic with integrated computer interface.
Digital metering, pin diode attenuation and
optional integrated linearizer for improved
intermodulation performance.
Global Applications
Meets International Safety Standard EN-60215,
Electromagnetic Compatibility 2004/108/EC
and Harmonic Standard EN-61000-3-2 to satisfy
worldwide requirements.
