TL25XJ Modular

X-Band
2.5 kW Modular SuperLinear® TWTA
Compact
Provides 2500 watts of equivalent linear power (1110 watts
operating) in a modular, 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 CW 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.
Efficient and Reliable
CPI SuperLinear® TWTAs are among the most power
efficient in the industry. This amplifier is optimized for
maximum efficiency at linear output operating levels.
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.
Easy to Maintain
