Wolfspeed GaN HEMT RF flyer

The 50V RF GaN HEMT from Wolfspeed is designed and manufactured with specific technical choices, making it a unique product

Wolfspeed (Infineon) offers a broad range of GaN RF products that are in high demand throughout the energy, ele-ctronics, industrial, transportation, and military telecommunications sectors. The company’s new CGHV40100 is a unique gallium-nitride (GaN) high-electron-mobility transistor operating from a 50-volt rail and up to 3-GHz.

The CGHV40100 includes a single GaN-on-SiC HEMT die with an area of 4.17mm2. To make the source connection, the device is manufactured on ultra-thin wafer with gold vias. The HEMT shows the typical GaN epitaxy structure for lateral device and a source-connected field plate.
