200W Compact Low Power Amplifier
for Satellite Communications
The VZU-6992EC
200 Watt TWT
Low Power
Amplifierhigh efficiency
in a compact
Easy to Maintain
Provides 200 watts of power in a 3 rack unit
package, digital ready, for wideband, single- and
multi-carrier satellite service in the 13.75-14.5
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 behind front panel door for easy
maintainability in the field.
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
fourteen 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 89/336/EEC and
Harmonic Standard EN-61000-3-2 to satisfy
worldwide requirements.
