Microsemi provides device support for the next-generation Iridium NEXT satellite constellation project

Electronic enthusiasts 8:1, a leading provider of differentiated semiconductor technology solutions for power, safety, reliability and performance, congratulations to Iridium CommunicaTIons Inc., Thales Alenia Space, SpaceX and its project subcontracting The company successfully launched the first batch of 10 Iridium NEXT satellites. Iridium NEXT is the Iridium next-generation satellite constellation that replaces and enhances its existing near-Earth orbit satellite network covering the globe. The project uses more than 200,000 devices from Microsemi, which are ideal for satellite communications applications.

As the largest commercial satellite constellation in space, Iridium NEXT uses more than 2,000 anti-radiation Megumi Mori programmable logic devices (FPGAs) including RTSX32SU, RTAX1000S and RT3PE3000L, as well as many JANS and JANTXV diodes, such as the popular 1N6638. , 1N5806 and 1N6640 gapless sealed diodes. These Microsemi devices are deployed for various satellite bus and payload applications on the Iridium NEXT satellite, while Microsemi's commercial FPGAs are used in SpaceX carrier rockets.

Ken O'Neill, director of aerospace marketing at Microsemis, said: "We warmly congratulate the Iridium NEXT team on the successful launch of the first 10 satellites. We are proud of our 60 years of space heritage and extensive space products. We are honored that high-reliability innovative FPGAs, power discretes, systems and power modules play a very important role in these next-generation commercial communications satellites. We will continue to fulfill our commitment to the aerospace and defense markets. , to provide customers with reliable products to help them complete their tasks in the most demanding environments."

Microsemi's discrete products include more than 8,000 certified product list (QPL)/certified manufacturer list (QML) devices, accounting for 60% of all certified products in the US Defense Logistics Agency (DLA) QPL/QML list. According to a report by Databeans, Inc. titled "2016 Military and Avionics Semiconductors," Microsemi is a leading supplier to the defense and aerospace semiconductor markets, accounting for approximately 20% of the market.

Microsemi's aerospace products include diodes, rectifiers, Zener diodes, transient voltage suppressors (TVS) and MOSFETs. In addition, its FPGAs offer several different density and performance level options, giving customers the flexibility to choose the optimal size for their application. These wide-ranging devices reflect the company's focus on providing differentiated solutions to the market, with commercial satellite communications being part of its ongoing commitment. In addition to discrete products, power DC to DC, hybrid, and FPGA combinations, the company's oscillators, motor control and telemetry devices are also ideal for specific satellite applications.

Microsemi is leading space innovation for more than sixty years

Microsemi has one of the industry's most comprehensive portfolio of space products, offering radiation-tolerant FPGAs, radiation-tolerant mixed-signal ICs, radiation-tolerant DC-DC converters, precision timing and frequency solutions, linear and POL hybrid circuits, and custom hybrid solutions. Solutions and radiation-resistant discrete devices, including the broadest portfolio of JANS Class diodes and bipolar products. Microsemi is committed to supporting products throughout the product lifecycle of a customer's project. The company continues to innovate and expand its product portfolio, adding the new LX7730 radiation-tolerant telemetry controller IC, providing key features for sensor monitoring, attitude and payload control, and the RTG4TM high-speed signal processing radiation-tolerant FPGA family. RTG4's reprogrammable flash technology provides comprehensive radiation-initiated configuration flip immunity in the most demanding radiation environments, unlike SRAM FPGA technology, which eliminates the need for configuration cleaning.
