Novel Structure
GaN epi-wafer high electron mobility transistor structures with an AlGaN back-barrier improve electron confinement – extremelyy important for telecommunication devices operating at very high frequencies, above 40 GHz. Thus, the already highly competitive QuanFINE structure that we can provide to our customers takes another step to achieve excellence when combined with our AlGaN back-barrier, pushing the performance limits of telecommunication devices even further.
The AlGaN back barrier technology is a further enhancement of SweGaN’s proprietary QuanFINE structure. Please contact us for more information on our AlGaN back barrier technology
Enhanced carrier confinement for RF devices
