Cree earns U.S. Dept. of Defense MRL 8 designation

Cree, Inc., a leader in gallium nitride (GaN) RF devices, has earned the U.S. Department of Defense (DoD) manufacturing readiness level eight (MRL 8) designation. Awarded for its production of GaN monolithic microwave integrated circuits (MMICs), this designation verifies Cree’s ability to provide assured, affordable and commercially viable production capabilities and capacities for items essential to national defense.

New Cree GaN HEMT die available via distribution

 Cree, Inc. has made seven new GaN HEMT die available through distribution via Mouser. Manufactured on silicon carbide (SiC) substrates using a either 0.4 or 0.25 μm gate length fabrication process, the gallium nitride (GaN) high electron mobility transistor (HEMT) die exhibit superior performance properties compared to silicon (Si) or gallium arsenide (GaAs) die, including: higher breakdown voltage, higher saturated electron drift velocity, higher thermal conductivity, and higher efficiency.

Cree introduces highest power and frequency plastic packaged GaN transistors

Cree, Inc. introduces the industry’s highest power continuous wave (CW) GaN HEMT RF transistors packaged in a dual-flat no-leads (DFN) format. Aimed at the cost-sensitive sub-100W commercial radar and data link amplifier market segments, the new 6- and 25-watt DFN transistors effectively obsolete the use of inefficient GaAs transistors in C- and X-Band frequencies and also enable the practical replacement of short life tube-based technology for commercial radar applications such as weather, marine and surveillance.
