Foundry Partners - Wolfspeed, A Cree Company

Wolfspeed, A Cree CompanyCree Overview Video on YouTube — In this video, Jeremy Fisher, Manager of the MMIC Design and Test Group at Cree, describes what Cree provides for mutual customers of Keysight EEsof EDA and Cree.

GaN-based HEMTs

Broadband performance - Enables high power, multi-octave bandwidth amplifiers

Wolfspeed's (a Cree Company) GaN HEMT MMIC processes are available for MMIC development using full-wafer service (FWS) or a shared multi-project MASK SET (SM) fabrication service. The process features high-power density (4 Watts/mm) transistors, slot vias, high reliability up to 225ºC operating junction temperatures, and scalable unit cells (1 to 8mm/Cell). The value of such MMICs is more power bandwidth and higher efficiency within a smaller footprint compared to other MMIC technologies.

Wolfspeed, a Cree Company has been assessed by the Department of Defense (DoD) to Manufacturing Readiness Level 8 and higher.
