Compact modular upgrade for GMR software defined tactical radio

摘要

A software-defined tactical radio solution meets the original JTRS SWaP goals by providing four complete software-defined 125 W (peak) radio channels in four modules that replace the four UT modules of the current GMR design, while retaining the GVA and NIU of the GMR. Two dual transceiver modules each include two transceivers based on OMAP processors. Two dual-channel power amplifier modules each include two 125 W (peak) amplifiers, each amplifier combining two GaN transistors combined in parallel. In embodiments, the OMAP processors include TM320C64xx DSP cores. In some embodiments, the OMAP processors are DM3730 processors. In various embodiments, each dual transceiver module includes a five Watt power amplifier. In embodiments, SINCGAR, SRW, and/or WNW waveforms are supported by software configuration. In some embodiments transceivers can be transitioned by software between waveforms.

1. A software-defined tactical mobile radio system that incorporates GMR components developed under the US Military JTRS program and meets the JTRS SWaP goals, the radio comprising:
a GMR Ground Vehicular Adaptor (GVA); a GMR Network Interface Unit (NIU) installed in the GVA; two Dual Integrated Core Engine Transceiver (DICE-T) universal transceiver modules, each DICE-T module being configured for installation in the GVA in place of a GMR UT module, each DICE-T module including two software defined radio transceivers, each of the software defined radio transceivers including a core engine (CE) based on an OMAP processor; and two dual-channel 125 W (peak) power amplifier (PA) modules, each PA module being configured for installation in the GVA in place of a GMR UT module, each PA module including two 125 W (peak) power amplifiers, each of the 125 W (peak) power amplifiers including two GaN transistors combined in parallel by two power combiners.
