Norsat Ku-Band 4 Watt BUC

Norsat Ku-Band 4 Watt BUC

The high performance Norsat Block Upconverter (BUC) upconverts and amplifies an input signal range at L-band (950-1450 MHz) to an output block in the Ku-band frequencies, which is then fed into an antenna for radiation to the satellite. This robust BUC can consistantly operate in the most demanding of weather conditions. Easily mounts to directly to the feed assembly and features an integrated lock detector to shut off the transmitter in the event of failure for safe, compliant operation. This is an ideal BUC for most all VSAT applications.
