Head of RF Energy Alliance announces magnetrons will be replaced by RF

Oregon, 22 March 2016

In an interview on solid-state RF energy, Dr. Klaus Werner explained that across multiple areas of applications, including cooking ovens, RF power will enable new applications or greatly improve existing ones.  “Magnetrons will eventually be replaced by solid-state RF power amplifier modules,” said Dr. Klaus, Executive Director RF Energy Alliance (RFEA), an association founded in 2014 with the goal of presenting solid-state RF energy’s true potential as a clean, highly efficient and controllable heat and power source.

RF solid-state power has numerous applications, including industrial heating and drying, ignition, lighting, and domestic and commercial cooking.  The fact that RF power offers the potential to improve product performance or enable new possibilities has stirred a lot of interest from companies across multiple industries worldwide, including some of the best known domestic appliance brands.

However, as with many new technologies, integrating RF power into new applications requires problem-solving skills.  “Achieving the desired performance at a competitive price isn’t always a trivial task,” explained Ben Zickel, CTO of Goji Research, the R&D affiliate of Goji.  “As a pioneer in the field of RF cooking, we had the privilege to be among the first to research and develop the technology in this space, and over the years we developed many important solutions to help bringing the technology to the market.”

Compared to the magnetron, the power source microwave ovens, which are sold by the million each year, RF technology is still far more expensive. “But the gaps are narrowing,” explained Ben.  “The work the RFEA does and investments by multiple players across the value chain will all contribute to the price reduction necessary for RF power to eventually replace the magnetron and improve the cooking experience in many millions of households worldwide.”

About RF Cooking

RF cooking utilizes a high power solid-state amplifier which, as part of a complete RF module, transmits radio wave energy into an object to heat it. Unlike the magnetron in a microwave oven, the digital RF module can accurately control the frequency, amplitude and phase of the radio-waves. When combined with Goji’s proprietary closed-feedback sensing algorithm, the RF module enables more uniform and consistent cooking results, while shortening and simplifying the cooking process.
