Solid-State Microwave Oven (Yes, An Oven) Makes Debut At IMS2012

Leonard Pelletier, applications support manager for Freescale's RF Division, introduces us to a new solid-state microwave oven design (a rarity at IMS!) that uses a Freescale RF transistor as an energy source, in place of the traditional magnetron. Advantages of this solid-state approach include increased longevity (mean time to failure of approximately 20 years, versus 500 hours for magnetron-based designs), ruggedness (for high-vibration applications, including mobile homes, airplanes, and other vehicles), and the ability to create alternative oven form factors. In addition, Pelletier shows us a Doherty configuration, 900 MHz RF transistor for cellular infrastructure applications that operates on a 48-volt VDD-based bias line, achieving power densities approaching 400 W.
