Cree Inc.

 Dr. Christopher Harris, European business development manager at Cree, Inc., will present “Using Cree^® GaN Large Signal Models in Microwave Office Simulation Tools” at the RF/Microwave PA Forum at European Microwave Week.  

 Cree, Inc., a leading global supplier of silicon carbide (SiC) and gallium nitride (GaN) wafers and devices, has developed a family of 50 V discrete GaN high electron mobility transistor (HEMT) die for operation up to 6 GHz.  

Cree, Inc. is enhancing its support of the European market by extending its partnership with APC Novacom.

 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, 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.

As high data rate applications put more strain on LTE wireless networks, innovative solutions such as small cell base stations (BTS) and carrier aggregation will be needed to bridge the bandwidth gap in high traffic areas. In response to broader bandwidth demand, Cree, Inc. introduces a family of GaN HEMT RF transistors that delivers industry-leading bandwidth and high efficiency performance to support today’s busy LTE networks.

Cree has added four new gallium nitride (GaN) high electron mobility transistors (HEMTs) to its product portfolio at Digi-Key, the sole distributor for Cree RF components. Respectively based on Cree’s high power density 50V, 0.25μm and 0.4μm GaN on silicon carbide (SiC) foundry processes, the new X-Band and S-Band components exhibit high efficiency, high power gain, and wide bandwidth capabilities.
