Update on RF-driven Plasma Lighting


Green technology has the potential to drive the next generation of research and development, boosting the high-tech economy, reducing our dependence on fossil fuels, lowering carbon emissions and addressing global warming. With these benefits in mind, RF-driven plasma lighting is gaining interest. The microwave light has an efficiency of more than 50 percent, compared with fluorescent tubes' efficiency of about 15% and traditional light bulbs, which emit only about 5 % of their energy conversion as light. This week we look at Ceravision Ltd., a leading innovator in this technology.

Competition Heats-up in GaN Foundry Services

Recent announcments from the major GaN foundry service providers indicate considerable market interest in these devices.

At last year’s IMS in Atlanta, both TriQuint and Cree rolled out competing GaN foundry services amid strong interest in the high-power RF technology. This year, RFMD took the stage to introduce their own GaN foundry services, which they did in a press conference hosted by Robert Van Buskirk, President of the company’s Multi-Market Products Group. As reported in this month’s cover story, “The New Power Brokers”, interest in GaN devices is being fueled by the high power density and high-temperature operation of these transistors.

The New Power Brokers: RFMD on GaN

Dave Aichele from RFMD talks to Microwave Journal about their GaN technology, the markets and the competition.
MWJ: What are the most significant benefits of GaN/LDMOS/HVFET? How does this compare to other high power devices?   RFMD: GaN based amplifiers provide the following significant benefits 1)       Higher efficiency for pulsed, CW saturated and linear applications which improve thermal requirements and energy usage.   GaN is...
