CPI VZX-2783C1

CPI 1.0kW X-Band TWT Amplifier
for Instrumentation Applications
X- Band
The VZX-2783C1
x-Band
1.0 kW TWT
High Power
Amplifier features
high efficiency and
power for EMC/EMI
testing.
Safety
Provides 1000 watts of power in the 8.0 to
12.75 GHz frequency band in a compact 19inch rack-mount dual drawer configuration for
wideband testing.
Conforms to international safety and EMC
compliance standards.
Efficient and Reliable
Employs a CPI dual-depressed collector helix
traveling wave tube which increases efficiency
by a nominal 20% over conventional single
collector TWTs, and a power supply designed
with a minimum number of parts for
maximum uptime.
Easy to Maintain
Modular design provides for easy installation
and maintainability in the field.
Worldwide Support
Backed by over two decades of satellite
communications experience, and CPI’s
worldwide 24-hour customer support
network that includes fifteen regional factory
service centers.
Simple to Operate
Integrated microprocessor control lets the user
adjust and monitor all operating parameters
from one easy-to-read local or remote panel,
using straightforward menu-driven commands.
