Midea Innovation: World's First Solid State RF Microwave Oven
Since Raytheon Company introduced the world's first commercial microwave oven in 1947, the traditional technology of magnetrons and transformers has been the technology of choice. There have not been any revolutionary innovations, including the shape and appearance, until now.
Today, Midea proudly announces that through exceptional collaboration between Midea Company, the innovation leader in the global microwave industry, and Freescale Semiconductor, the world leader in RF power semiconductors, the world’s first solid state RF microwave oven is now available. Midea will be demonstrating this technology at International Microwave Symposium 2012, in Montreal, Canada, June 19-21, in Freescale’s booth #901.
Midea RF microwave oven has disrupted the technology model of the industry
Midea has created a new age in the microwave oven industry, leveraging years of innovation of LDMOS technology in the communications industry. The solid state RF microwave oven has no magnetron or heavy transformer. Among key breakthroughs, was the invention of an oscillation scheme that produces 2450 MHz, in the ISM band designated for industrial, scientific and medical uses, including commercial microwave ovens. This breakthrough is paramount to the digital camera replacing the film camera.
“We are happy to collaborate with Midea in this evolution of the microwave oven industry,” said Ritu Favre, vice president and general manager of Freescale’s RF Division. “As the leader in RF power semiconductors, this represents a continued effort to support businesses that go beyond traditional cellular infrastructure applications.”
Seven key technology breakthroughs in Midea RF microwave oven
Midea has made seven key breakthroughs in core technology research through the close collaboration between microwave oven experts at Midea and RF power experts at Freescale Semiconductor. They include RF high-power synthesis technology, RF output power adjustable technology, RF microwave oven heating efficiency promotion technology, heating frequency automatic control technology, the technology of RF microwave feeding, RF power source load rigid lifting technology and RF microwave oven matching technology.
Unique features in product performance and function
Compared to traditional microwave ovens, the Midea solid state RF microwave oven has many advantages including high intelligence, long life, low voltage operation, low noise, full DC operation capability and small volume. It has the fundamental innovation in overall form factor and appearance, green electricity and ease of use.
The intellectual property in Midea RF microwave oven
So far, Midea Company has applied for seven patents in RF microwave oven technology, including four invention patents.
Midea has successfully developed the commercial application in the world
At present, Midea is first to develop a commercial application of an RF microwave oven at 2450 MHz band with three power levels including 150W , 300W and 600W output. Midea plans to continue research and development in order to launch higher output power microwave ovens using Freescale solid state RF power semiconductor technology.
