CPI VZL-2780C2

CPI 500W S/C-Band TWT Amplifier
for Instrumentation Applications
S/C - Band
The VZS/C-2780C2
S/C-Band
500 watt TWT
High Power Amplifier
features high
efficiency, small
size and an integral
computer interface.
Safety
Provides 500 watts of power in the 2.0 to
8.0 GHz frequency band in a compact 19-inch
rack-mount dual drawer configuration for
wideband testing.
Conforms to international safety and EMC
compliance standards.
Efficient and Reliable
Employs CPI dual-depressed collector helix
traveling wave tubes, increasing 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.
Includes a built-in interface and serial bus for
operation from the station computer.
