The BJES10 Q-band Redundant LNA system consists of two separated main sub-blocks, such as LNA Plate

called as BJEL10, and Indoor Controller called as BJEI10, according to the block diagram below. The LNA Plate

is designed for hub-mounted conditions, as it is going to be assembled to the antenna, while the indoor

controller is located in a 19” rack, and it will be used in the control room to monitor and control the redundant

LNA system. The indoor controller has redundant hot swappable AC/DC power supply for higher reliability. The

complete system can handle two additional LNA units for tracking purposes.
