Northrop Grumman Corporation SATCOM Antenna Interface Unit (AIU)

Description
Northrop Grumman's UHF SATCOM Antenna Interface Unit provides improved receive sensitivity and receive protection for the Ground Mobile Radio (GMR) system. The SATCOM AIU is a Line Replaceable Unit (LRU) that is part of a Joint Tactical Radio System (JTRS) Cluster 1 Joint Tactical Radio (JTR) Set. The SATCOM AIU includes a low noise amplifier (LNA) component and block filtering required to achieve the receive performance parameters for the UHF SATCOM waveforms. The AIU is mounted in close proximity to the antennas to minimize losses between the antennas and internal LNA. In addition to the receive path, a low loss bypass path is provided in transmit mode routing the transceiver to one of two output ports for a High Angle or Low Angle Antenna element. Control information from the transceiver is decoded to select the antenna port desired, transmit or receive mode and to route built in test status back to the transceiver.
