Satellites & Space Systems


Radiation in Space
There are several types of radiation experienced by semiconductors in space. Devices in satellites in orbit around our earth, or in exploration satellites visiting the most distant parts of our solar system, all experience some form of high-energy radiation bombardment. Three of the primary types of radiation are gamma radiation, neutron radiation, and heavy ion bombardment.
Failure Mechanisms
An energetic particle can cause damage to a semiconductor in three primary ways; it can cause traps in non-conducting layers, it can cause physical damage to the crystal – also called displacement damage, or it can generate a cloud of electron-hole pairs that will cause the device to momentarily conduct, and possibly burn out in the process.
Our Partners for Space Qualified Products 
Through our representation Allied Data Systems has a complete range of radiation hardened parts for use in space environments. These parts come from VPT Power for DC-DC Converters and Point of Load Converters, EPC Space for GaN discrete parts and DDC for space qualified Single Board Computers, Memory, Logic, Amplifiers, A/D and D/A converters. We are also able to organise specific testing for space certification.


VPT’s SV Series of DC-DC converters are mission proven in systems launching for LEO, MEO, GEO, and deep space missions. Qualified to MIL-PRF-38534 Class K on DLA SMDs, these off-the-shelf units help you get your system off the ground fast.
Combine VPT’s extensive family of DC-DC converters for space with VPT’s point of load converters for space to create a light weight, extremely efficient, space-ready power system.

DDC is a leading supplier of space qualified SBCs and radiation hardened components. Utilizing multiple radiation hardening techniques, DDC's space solutions incorporate one or more of the following elements: RAD-PAK® technology, Rad Hard by Design, Triple Mode Redundancy (TMR), and Error-Correction Codes (ECC). DDC's space-qualified and field proven solutions are engineered for space’s extreme environmental requirements, while reducing space, weight, and power consumption, along with total cost of ownership.
Radiation Hardening Techniques
Advanced Commercially-Available Components with RAD-PAK® Technology
DDC’s RAD-PAK® technology improves TID (Total Ionizing Dose) hardness by shielding the semiconductor die. RAD-PAK® enables the latest commercially-available electronic integrated circuits to be deployed on various space missions, by tailoring the shielding thickness to mitigate the specific space-radiation environment.

Radiation Hardened by Design & Process
DDC has successfully deployed mixed-signal and digital ASICs on multiple space missions via its portfolio of MIL-STD-1553 interface, motion feedback, and motor control and drive solutions. To mitigate TID & SEE (Single Event Effects) these Multi-Chip Modules (MCMs) incorporate ICs employing the latest state-of-the-art rad-hard by design techniques, as well as modern dielectrically-isolated semiconductor processes. DDC selectively applies rad-hard libraries and or processes that are proven to be radiation hardened to optimize performance.

Triple Mode Redundancy (TMR) & Error-Correction Codes (ECC)
In our high-reliability subsystems, DDC employs TMR and ECC to mitigate TID & SEE. In both methods, failure-free operation is ensured by the use of redundancy. In the case of TMR, the output of three processors is run through a voting algorithm, and an error in one processor may then be “outvoted” by the other two processors. Additionally, incorrect data is resolved by applying Error Correction Codes and computing algorithms with redundant data-bits. With multiple error correction tools, the level of correction can be tailored to the severity of the environment.
