DESIGN OVERVIEW:
The Ka-Band BUCs are the next generation of the world’s most compact and efficient feed-horn & boom-arm mountable
Ka-Band BUCs in the industry handling the output power up to 40W. We’ve picked the most mature, reliable and provento be highly efficient amplifiers with internal overdrive protection. Its weatherproof and robust Hyper-Light package isconstructed with the most advanced materials and mechanical precision engineering in mind, taking the MTBF to the nextlevel of at least 15 years during normal operation. Each unit is vigorously tested at our California facility according to ourAcceptance Testing Procedure.
