With one of the industry’s most comprehensive portfolios of space products, Microsemi provides radiation hardened and radiation-tolerant solutions ranging from diodes, transistors and power converters, to FPGAs, ASICs, RF components, custom semiconductor packaging, and integrated power distribution systems.
Microsemi’s space-proven, radiation-tolerant FPGAs provide a wide range of gate counts and hardwired multiply-accumulate blocks for fast, efficient digital signal processing. They also feature QML qualification to classes Q and V, and are available in a variety of package types and sizes. Our FPGAs have survived more than 20 million device-hours of independent reliability testing, and performed flight critical functions in space systems orbiting around the Earth, Moon, Mars, Venus and the sun. They also have been used on missions to the surface of Mars, and into the furthest reaches of the solar system. Microsemi’s innovations include radiation-hardening-by-design techniques that protect against single event upset (SEU) radiation effects, novel packaging technologies to enable integration of FPGAs into hybrids and multi-chip modules, and high-density ceramic column grid array packaging. Product family specifications include:
Precise Timing and Frequency Solutions
Microsemi has been designing and building Space Qualified Oscillators and Cesium Clocks for over 40 years. High-performance frequency and timing products make modern communications and navigation possible, and set the standards by which time it's self can be measured everywhere. Our cesium clocks have worked on GPS Block I and II, IIA, and IIF Satellites. Microsemi OCXOs have been used in multiple satellites such as GPS III, SBIRS, MUOS, PAN, COSMO, KOMPSAT, STEREO, and numerous classified programs.
Radiation-Hardened Power Supplies
Microsemi has delivered thousands of highly reliable standard and custom radiation-hardened DC-DC power supplies to support space missions and military and commercial avionics system development programs. We offer:
Rad-hard Bipolar Transistors and Diodes, and Solar Diodes
Microsemi’s discrete solutions are qualified to MIL-PRF-19500, and the company has more DLA slash sheet qualifications than any other manufacturer of space-level discrete products. We were the first diode manufacturer selected by the U.S. military services as a source of supply to qualify product to the highest specified reliability level. We have expanded our offering to include a growing range of space solutions and capabilities including:
Integrated Custom Products
Microsemi’s integrated custom products have been used in a broad array of space systems including satellite payloads and sub-orbital rockets. Leveraging our extensive expertise in MIL-PRF-38534 class K multichip system-in-package technology, we combine radiation-tolerant and radiation-hardened silicon into space-saving, reduced-weight, class K-compliant sub-systems. Typical products have included solutions with multiple organizations of memories, gate arrays and processors in various hermetically-sealed ceramic packages.
Microsemi’s facility in Phoenix, Arizona is Defense Microelectronics Activity (DMEA) accredited as a trusted supplier of radiation-tolerant FPGAs. This location is fully ITAR compliant and includes a DOD secure area.
Microsemi currently offers nearly 30 radiation-hardened MOSFETs qualified to Defense Logistics Agency (DLA) slash sheets 601, 603, 614, 615 and 630, and we are pursuing additional qualifications. We offer numerous customer benefits including:
Hybrids for Space Applications
Microsemi designs and manufactures high-reliability micro-circuits qualified to MIL- PRF-38534 performance requirements. We produce standard and custom power conversion products including linear regulators and switching converters that are qualified for use in harsh radiation environments. We offer customers the following capabilities:
Radiation Hardened Integrated Circuits
Microsemi has a long history of providing successful and reliable industry-standard, radiation-tolerant integrated circuits including:
Our access to several radiation-tolerant process technologies has enabled us to offer custom sensor and driver ASIC solutions with voltages ranging up to 120V. These ASICs provide space-saving solutions for key embedded satellite functions including high-side drivers, motor control and telemetry.
RF Integrated Solutions
Microsemi has a long history of supplying RF and microwave diodes, transistors and control devices for domestic and international space applications. We offer dedicated service and provide the necessary performance, packaging and testing that is required for these demanding applications. Key features include:
Our latest generation of RF microwave transistors is based on silicon carbide (SiC) and gallium nitride (GaN) wide band gap materials, enhancing system performance and reliability. These innovative devices allow manufacturers to reduced component count, size, and weight, while providing increased bandwidth and reduced operating temperature.
Microsemi also provides low noise and high-power RF amplifiers, converters and transceivers, and multifunction RF transceivers through 110 GHz for high-reliability defense applications.
