What is a BUC?
A BUC (Block Up-Converter) takes an L-band input and transmits it upstream to the satellite on Ka, Ku, or C band.
BUC's are rated according to their output power. A low power Ka band BUC can transmit with as little as 2 watts, while a high power C-band BUC can transmit with as much as 200 watts.
The BUC is sometimes referred to as the TXB (Transmission Block).
