SpaceBridge SBB0800K 800W Ku-Band Outdoor GaN BUC

SpaceBridge SBB0800K 800W Ku-Band Outdoor GaN BUC

The SpaceBridge SBB0800K is an 800 W Ku-band outdoor block upconverter (BUC) powered by advanced Gen III GaN technology. Designed for satellite contribution, DTH distribution, cellular backhaul and HTS/UHTS VSAT hubs, it delivers high-linearity amplification for multicarrier and multi-transponder applications. Its IP67 enclosure, built-in 1:1 and 2:1 redundancy, and Ethernet monitoring support reliable operation in demanding outdoor installations.
