Sir James Dyson, best known as the inventor of the bagless vacuum cleaner, said “Manufacturing is more than just putting parts together. It's coming up with ideas, testing principles and perfecting the engineering, as well as final assembly.” He couldn’t have said it better. The manufacturing of any product starts even before you have assembled the first component: it starts at the drawing board level. RF solid-state power modules are, of course, no exception. Just as you design the product to meet performance targets, usability, reliability and certification, you must also design for mass manufacturing and testing.
In the heart of every RF solid-state cooking appliance is an RF module. This high power amplifier-transceiver is capable of converting DC power into high power RF energy, with high-level control over frequency, amplitude and phase. Though the RF module is a critical component in the appliance, it is by no means the only one. Cooking appliances have multiple electronic and mechanical parts and the RF module must live in the same environment with a suitable mechanical, electrical and RF interface. Thus, unlike power amplifiers in other markets, RF modules must meet very strict requirements in areas such as space, temperature and price.

Our scientists and engineers at Goji Research have worked on Goji’s technology for over a decade now. By going through multiple design iterations and finalizing production transfer with a world-class electronics manufacturer, we have a learned a lot about the design and serial manufacture of RF modules.
The path of development and production of new technologies such as the RF module is riddled with challenges, some anticipated and some not. To address these effectively, we have created a culture that promotes innovation and out-of-the-box problem solving, yet respects our product development processes. Through this approach, we have successfully passed many obstacles along the way and have developed a truly unique product. Moreover, we have accumulated the unrivaled learning and experience which gives us our expertise, one of the unique values we bring our customers today.
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.
Goji develops and markets RF cooking technologies for household, commercial and industrial applications in the food industry. The novel Goji™ technology facilitates controlled and responsive heating, delivering unprecedented cooking performance. The company holds a broad IP portfolio, with over 200 issued and pending patents on its technology. Goji provides a full range of licensing, design and manufacturing services to commercial and white goods appliance manufacturers. For more information, visit www.gojifoodsolutions.com.
