Power Amplifier and Low Noise Amplifier Power Supplies
The power amplifiers and LNAs are supplied with 48V DC via the AC/DC power supplies located at the
bottom of the rack. The number of modules contained in the shelves depends on the number of sectors
that are supported. The rack contains enough power supplies to support n+1 redundancy, meaning
that if a module were to fail, the remaining modules would be sufficient to support the load.
