Cree/Wolfspeed Releases X-Band Radar Devices


Availability of four new GaN on SiC MMIC devices enable designers to improve RF system size, weight, and power

Cree/Wolfspeed is introducing four new multi-stage GaN on SiC MMIC devices, extending its range of RF solutions for a diverse array of pulsed and continuous wave X-band phased array applications, including marine, weather surveillance and emerging unmanned aerial system radars.

Using Wolfspeed GaN on SiC technology, these new devices deliver high power-added efficiency (PAE) in small, industry standard packages that allow designers to achieve maximum performance with smaller systems that consume less power.

“Cree/Wolfspeed’s new X-band offerings provide today’s design engineers with a wide breadth of options for systems requiring high efficiency transmit solutions in challenging form factors such as those needed for active phased array radar applications,” said Jim Milligan, senior director foundry, aerospace and defense at Cree l Wolfspeed. “Using Wolfspeed GaN on SiC solutions enables them to meet the critical RF system requirements related to smaller size, lighter weight, and higher power (SWaP) while reaching new levels of performance.”

The X-band portfolio offers solutions that support multiple stages of gain, thereby reducing the number of devices needed in a transmit chain. They come in a variety of power levels to optimise system performance and are offered in multiple platforms to optimize system architecture. See Table 1 for more product details and performance data.
