750W Compact Medium Power Amplifier
for Satellite Communications
X-Band
The VZX-6987A7
750 Watt TWT
Medium Power
Amplifier—
high efficiency in a
compact package.
Compact
Easy to Maintain
Provides 750 watts of power in a 5 rack unit
package, digital ready, for wideband, single- and
multi-carrier satellite service in the 7.9 - 8.4 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.
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.
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.
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.
