2 . 2 5 k W S u p e r L i n e a r tm C o m p a c t T W TA
Global Applications
Provides 2250 watts of peak power (1000 watts
operating) in a compact nine rack-unit package,
digital ready, for wideband, single- and multicarrier satellite service in the 5.85 - 6.65 GHz
frequency band. Designed to operate at 1000
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.

(in any 40 MHz band)
1Prime power AC line unbalance not to exceed 3%. Excess imbalance may cause
an increase in residual RF noise (AM, FM and PM). Phase noise increase is typically 2.5 dB / %
2AC current harmonic content: less than 20%, primarily fifth and seventh harmonics. Harmonics
must be considered when choosing UPS sources.
