Wolfspeed, A Cree Company

Foundry Partner Wolfspeed - Jeremy Fisher

Wolfspeed Provides PDKs for Keysight ADS  — In this video, Jeremy Fisher, the Manager of the MMIC Design and Test Group, discusses how Wolfspeed, A Cree Company partners with Keysight Technologies.

Electrothermal Simulation using the Wolfspeed ADS PDK

Electrothermal Simulation using the Wolfspeed ADS PDK  — This is a short demonstration of how the Wolfspeed ADS PDK is configured to work with the ADS electrothermal simulator to co-simulate electrical and thermal performance. This allows designers to quickly understand the impact of thermal effects on their circuit designs, and account for those effects during the design process.

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.
