Janet Barth spent most of her career at the Goddard Space Flight Center, in Greenbelt, Md.—which put her in the middle of some of NASA’s most exciting projects of the past 40 years.

She joined the center as a co-op student and retired in 2014 as chief of its electrical engineering division. She had a hand in Hubble Space Telescope servicing missions, launching the Lunar Reconnaissance Orbiter and the Magnetospheric Multiscale mission, and developing the James Webb Space Telescope.

A Diamond "Blanket" Can Cool the Transistors Needed for 6G

Gallium nitride transistors have struggled to handle the thermal load of high-frequency electronics

High-power radio-frequency electronics are a hot commodity, both figuratively and literally. The transistors needed to amplify 5G and future 6G signals are struggling to handle the thermal load, causing a bottleneck in development. Engineers in the United States and England have teamed up to demonstrate a promising solution—swaddling individual transistors in a blanket of thermally conductive diamond to keep them cool.

“Thermal issues are currently one of the biggest bottlenecks that are plaguing any kind of microelectronics,” says team lead Srabanti Chowdhury, professor of electrical engineering at Stanford University. “We asked ourselves ‘can we perform device cooling at the very material level without paying a penalty in electrical performance?’”
