ZYNQ UltraScale+ Digital RF Transceiver (UDRT)

A 3U VPX processor based on the Xilinx XQ-ZU19EG Multi-Processor System on Chip (MPSoC). A radiation-mitigated design, the processor includes on-board DDR4, NAND and redundant NOR memory, as well as a high-speed mezzanine site. Mezzanine cards include a 1 TB SSD or > 3 GSps Dual ADC/DAC with JES204B clocking; customization available. On-orbit since 2020.

On-Orbit Processing and RF

Trident’s UDRT is based on our powerful, flexible multifunction RF and processing architecture, providing programmability over all key RF/Processing features in a very small size, weight, and power footprint. A mission enabling design, the UDRT can be incorporated at the module level or used as part of Trident’s MFREU Products.

Mission Ready

TRL9 on several LEO missions (GEO 2022), a proven Radiation Effects Mitigated architecture, coupled with radiation tolerant components, redundancy and a robust mechanical design, provide a low C-SWaP, high reliability module for a wide range of applications. Hardware, Software, Firmware customization available with a wide range of FW/SW deployment options.
