1.3.5 Block Up Converter Input Option
TheHPODamplifier,whendeliveredfromthefa ctorywithaninternalBlockUpConverter(BUC),
translates an L‐Band input carrier to the desired output frequency (C‐, X‐, or Ku‐). Local
Oscillator(LO)frequenciesareasfollows:
BUC-4000 C, X, Ku, Ka
Band Frequency LO Frequency Inverting
C-Band 5850 MHz-to-6650 MHz 4900 MHz No
X-Band 7900 MHz-to-8400 MHz 6950 MHz No
Ku-Band-W 13.75 GHz-to-14.50 GHz 12.800 GHz No
The same Ku‐Band BUC is installed independent of amplifier bandwidth. Therefore, the
“standard” 14.0 GHz‐to‐14.5 GHz HPOD has an L‐Band frequency range of 1200 MHz‐to‐1700
MHz that translates up to 14.0 GHz‐to‐14.5 GHz, while the “Extended” 13.75 GHz‐to‐14.5 GHz
HPODtranslatesL‐Bandfrequen
ciesfrom950MHz‐to‐1700MHzupto13.75GHz‐to‐14.5GHz.
