ENERAL

The Block Up Converter (BUC) translates the L-Band carrier output from the IDU (in the 950 to

1750 MHz range) to C- or Ku-Band frequencies typically between:

•

C-Band: 5.845 and 6.425 GHz and amplifies the carrier to the desired TX power level.

•

Ku-Band: 14.0 and 14.5 GHz and amplifies the carrier to the desired TX power level.

The local oscillator of the BUC locks to the 10 MHz reference signal from the IDU in order to

provide an accurate frequency translation. In the event the BUC cannot lock to the 10 MHz

reference, the output carrier is muted to prevent interference with adjacent carriers.
