Radiation tolerant products are key as Juno enters Jupiter orbit

A wide variety of Microsemi’s radiation tolerant products were used in mission critical applications during Juno’s launch and journey across the solar system, and continue to support the historic mission in the hostile, intense radiation environment around Jupiter.

Over the next few months, Juno's mission and science teams will complete the transition to the final 14 day science orbit and initiate formal collection of scientific data. Microsemi’s radiation tolerant field programmable gate arrays (FPGAs) from the RTSX-SU and RTAX-S product families are in use within the space vehicle’s command and control systems, and in various instruments which have now been deployed and are returning scientific data. Microsemi’s high and low voltage radiation hardened power supply modules support guidance and controls systems on board the Juno spacecraft. In addition, a broad range of Microsemi’s portfolio of high reliability discrete diode and transistor technologies are used in many of the mission critical avionics and platform functions.

“We are honoured yet again to support NASA’s mission as we leverage Microsemi’s nearly 60 years of experience providing high reliability semiconductor solutions for groundbreaking US space programmes,” said James J. Peterson, Chairman and CEO of Microsemi. “This demonstrates the high quality of our radiation tolerant and radiation hardened products, as well as our commitment to our space customers who depend on our expertise to complete their missions even in the most hostile and inhospitable environments.”
