Wolfspeed launches multi-stage GaN-on-SiC MMICs for X-band phased-array radar
Cree | Wolfspeed of Durham, NC, USA has introduced four new multi-stage gallium nitride on silicon carbide (GaN-on-SiC) monolithic microwave integrated circuit (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, the 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, says the firm.
“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,” says Jim Milligan, senior director foundry, aerospace & defense at Cree | 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,” he adds.
The firm’s X-band portfolio offers solutions that support multiple stages of gain, reducing the number of devices that are needed in a transmit chain. They come in a variety of power levels to optimize system performance and are offered in multiple platforms to optimize system architecture.
