Abstract : The report presents the design philosophy, system and unit descriptions and the test results achieved for the AN/GRC-173(XW-1) digital Radio Set. The system consists of a Digital Group, Radio Group and Orderwire Group colocated within a modified S-141 shelter, and an Antenna Group mounted externally to the shelter. The Digital Group performs the function of interfacing with a mixture of digital data sources such as secure digitized TV, videophone, TDM equipment such as the Multiplexer Set AN/GSC-24(V), and produces a high-speed (235.93 MB/S) digital data stream for transmission and reception by the Radio Group and Antenna Group as DPSK modulated signals in the 36.0 to 38.6 GHz frequency band. Detailed functional descriptions of the units comprising the Digital Group and Radio Group as well as the individual circuit cards and components are presented. (Modified author abstract)
