2.25/2.50 kW TWT High Power Amplifier
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.
Provides 2250 or 2500 watts of power in the
7.9 to 8.4 GHz frequency band in a compact
19-inch rack-mount dual drawer configuration,
digital ready, for wideband, single- and multicarrier satellite service.
