Yole_GaN-Si_marketpostion_may2016

 

Two years ago, Yole Développement (Yole) and its sister company KnowMadepredicted
that GaN-on-Si would be widely adopted by power electronics and RF applications
because of its lower system cost and CMOS compatibility. The global market for GaN RF applications reached US$298.5 million in
2015 and is expected to still grow dramatically. Yole thinks that this market size may be the reason that there is a
dispute
between MACOM and Infineon and potentially others. It all started when MACOM
acquired Nitronex in February 2014. This transaction provided MACOM with the GaN-on-Si
technology process and materials for RF and other applications. At the end of
March, the company announced an IP licensing program. Today, the Nitronex
patents are widely used within the power electronics and RF sectors. Within
this context, MACOM could very well initiate many other legal actions. This
will be worth following. You can find out more in the GaN-on-Silicon
Substrate Patent Investigation report
from Yole.

First redundant power supply with GaN FETs

 

In
significant transistor news, Telcodium partnered with Transphorm to introduce the
first-ever redundant power supplies using GaN FETs. This is what the industry
has been waiting for, a power supply that replaces a typical three-module power supply architecture (two
power supply bricks and one IBC) with a single power module with redundant AC
feeds. The module operates at 94% system efficiency, is 30% smaller than the
two brick design, and eliminates the standalone IBC. Telcodium says the design pairs
a patented front-end circuitry with the JEDEC-qualified 650V GaN FET, available from Transphorm. The
resulting AC Series enables data center, server and telecommunication
manufacturers to develop smaller, high-performing systems that can virtually
eliminate power supply-related failures. For Series details, see telcodium.com. 

 

GaN Systems launches resource for placing GaN

 

GaN
Systems launches an online portal and
newsroom
solely focused on GaN power innovation. It helps keep the media
and power design engineers up-to-date with respect to GaN innovations, and
designing GaN transistors into electronic systems. Power industry professionals
will have access to a central repository that contains press releases, videos,
articles, newsletters, market dynamics and other resources about GaN
transistors and GaN innovations.
