Wide Bandgap Semiconductor Materials & Microwave PAs - Webinar

Find out more at http://explorerf.com/gallium-nitride1.... This is a FREE webinar on wide bandgap semiconductor materials and devices with a specific focus on Gallium Nitride (GaN) High Electron Mobility Transistors (HEMTs) as applied to Microwave Power Amplifiers. The topics presented in this webinar are summarised below: Introduction High Power Microwave PAs Vacuum Electron Devices VS Solid State Transistors Solid State PAs Performance Limitations Desirable Semiconductor Material Properties Wide Bandgap Materials (SiC, GaN, Diamond) High Electron Mobility Transistors (HEMTs) Heterostructures and Modulation Doping Performance Enhancements at Microwave Frequencies Gallium Nitride (GaN) HEMTs Structure Pros & Cons Polarisation Effects Surface States Virtual Gate Buffer Traps Current Collapse Challenges of Pulse I-V characterisation Drain Current Transients Experimental Examples: Cree and Nitronex Improvements Reducing Trapping Effects Enhancing Performance with Field Plates Commercial availability Conclusions Find out more at http://explorerf.com/gallium-nitride.... The videos featured in my multimedia textbook "Conquer Radio Frequency" are now available on my YouTube channel! They are presented in sections, each corresponding to one of the five chapters, which may be easily accessed from the channel's home page    / rfmicrowave  . A link to download the e-book is also provided in each video description. The material may also be accessed at http://explorerf.com/crf.html Francesco Fornetti
