Microwave heating technology is close to a revolution. Solid state electronics can now deliver comparable power levels to the magnetron tubes which has been the engine of the microwave ovens since the first products were launched. The new technology brings with it many new techniques that can significantly enhance the control of energy delivery. These techniques represent scope for innovation that will change the user’s experience of cooking and heating with high power RF energy. There is no one-size-fits-all approach and, as with any technology, the critical factor in a successful product introduction lies in understanding the application-specific requirements. There is still place for both technologies, magnetron tubes and solid state transistors and the selection of the proper technology solution that meets demanding customer and infrastructure requirements can only be done in hands of qualified professionals.
