Device Models for Enhancement Mode GaN Transistors
Efficient Power Conversion Corporation (EPC) have announced that the company has made available updated device models for all of its enhancement mode gallium nitride (eGaNTM) transistors on its web site.
These updates improve the robustness of the models without changing the core equations. Performance predictions with the new models will be consistent with previous versions of EPC SPICE models.
The TGA2572 delivers 20W for Ku-band (14-16 GHz) defense and commercial communications systems. The new device is fabricated using TriQuint’s production-released GaN on SiC process; it typically offers 30% PAE and 24dBm of small signal gain. Offered in die and packaged forms, TGA2572 samples will be available in early 2011. Contact product marketing for details.
“TriQuint’s gallium nitride portfolio offers the performance and reliability that defense and aerospace customers demand,” remarked Grant Wilcox, TriQuint Marketing Manager. “Our new TGA2572 delivers high gain as well as excellent power added efficiency. As a leader in both GaN and GaAs technologies, you can rely on TriQuint to provide the design assistance, service and product leadership demanded for high-reliability mission effectiveness.”
TriQuint’s expertise in gallium nitride (GaN), gallium arsenide / high-voltage GaAs pHEMT, surface acoustic and bulk acoustic wave (SAW / BAW), low- cost packaged devices and monolithic microwave integrated circuits (MMICs) has made us a leading supplier of RF system components to Boeing Company, Lockheed Martin Corporation, Northrop Grumman, Raytheon and other major defense contractors. TriQuint supplies RF innovation for consumer retail products including mobile devices, wireless LAN, triple-play CATV systems, optical and
TSPICE, PSPICE, LTSPICE, and Spectre device models are provided to help designers of advanced eGaN-based power conversion circuits and systems understand the value of the EPC eGaN power transistor family and reduce their time-to-market with benchmark products.
EPC has also written an application note to help users understand eGaNTM transistor capabilities and the applicability of the SPICE models. This application note is available at http://epc-co. com/epc/documents/product-training/Circuit_ Simulations_Using_SPICE.pdf.
