Re-programmable Multi-Function RF
Trident’s SQDRT 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 SQDRT can be incorporated at the module level or used as part of Trident’s MFREU Products.
Mission Ready
TRL9 with multiple RF modalities, a mission-ready solution using radiation-hardened parts, redundancy, a robust mechanical design and multiple build options to
provide a low C-SWaP, high performance module. Reference designs and custom FW development available as well as custom integration for a wide range of missions.
