CPI 2.25 and 2.50 kW SuperLinear tm TWT Amplifiers
for Satellite Communications
X- Band
The TL22XI and
Up to 2.5 kW (1110 W
operating) TWT
Compact High Power
Amplifiers, featuring
high efficiency, small
size and integral
computer interface.
Global Applications
Provides 2250 or 2500 watts of equivalent
linear power (1000 or 1110 watts operating)
in a compact nine rack-unit package, digital
ready, for wideband, single- and multi-carrier
satellite service in the 7.9 – 8.4 GHz frequency
band. Designed to operate at up to 1260 watts
flange linear power for multi-carrier uplinks.
Ideal for transportable and fixed earth station
applications where space and prime power
are at a premium. 30% smaller than
traditional HPAs.
Meets International Safety Standard
EN-60215 and EMC Standard EEC 89/336
to satisfy worldwide requirements.
Efficient and Reliable
Employs an ultra-high efficiency dual-depressed
collector helix traveling wave tube backed
by many years of field-proven experience in
airborne and military applications. The collector
design is optimized for super-cool operation.
Easy to Maintain
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 two decades of satellite
communications experience, and CPI’s
worldwide 24-hour customer support
network that includes sixteen regional
factory service centers.
Simple to Operate
User-friendly microprocessor-controlled
logic with integrated computer interface,
digital metering, pin diode attenuation,
optional integrated linearizer for improved
intermodulation performance, and BUC option
for use with L-band modems.
