DTM-DLM - Data Link Module “DTM-DLM” “DTM is a compact, FPGA based, modular and fully interoperable base band Data-Link System for a secured and anti-jamming anti radio communication. The “DTM-DLM” “DTM system is based on the DTM® architecture, to deliver an unmatched point-topoint point data communication using the CDMA (Code Division Multiple Access) technology. It can be embedded in platforms which are mobile, have a complex dynamics, evolve in in a very hostile environment conditions and where space is a big constraint. Functionalities The “DTM-DLM” range of products come as a plug-in plug module between the Radio-Frequency Frequency unit and the onboard computer of the platform and is equipped with different appropriate interfaces like RS422 and MIL1553B for Airborne application and Ethernet for ground application. The unit is finely designed to be deployed in aerial vehicle such as UAV, Missiles, Guided Munitions or any mobile platform: Applications In missiles, DTM-DLM can be used to receive target data updates or any commands from the ground firing unit or from airborne systems and provide downlink for video, imagery, data transmission, telemetry telemetry. • With its weight just less than 150gms and its size approximately 70mm x 65mm x 20mm can be a major solution for platforms where space is limited. • Provides a multi-channel channel secured communication with a cutting edge technology based on CDMA Gold code 1023. This ensures a low probability of interception. In UAV, in addition to above above, local recording of the compressed video data is possible for each sortie. • Offers an outstanding anti-jamming jamming sensitivity up to 27dB with 1023 code which allows the communication to be efficient even in the worst jamming scenario. Key Features • Innovative technology allows HIGH SPEED CDMA DMA for the given bandwidth or reduced bandwidth andwidth for the given data rate or increased anti jamming margin for the given data rate and bandwidth. • Configurable one or two way communication. • Different models to choose from HIGHT DATA RATE / LOW BANDWIDTH / HIGH ANTI ANTI-JAMMING / FHSS. • Compact dimension and light weight. • Universal 5V DC power supply. • High level of secured transmission. • Interfaces with civil and military protocols. • Incorporates multi-channel channel transceiver • Allow user interface code integration to save additional hardware. • Integration into RF unit saves space and testing cost. • Flight proven.
