2.25 kW Compact TWTA
Global Applications
Provides 2250 watts of CW power 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.
Ideal for transportable and fixed earth station
applications where space and prime power
are at a premium. 30% smaller than
traditional HPAs.
