Low-Voltage Magnetron Application for Microwave Cooking

System requirements for domestic electronic ovens are outlined with emphasis on low cost and long life. A low-voltage magnetron permits operation from a voltage doubler supply, thus avoiding use of an expensive plate transformer. Magnetron design factors include frequency, power, and tolerance to a wide range of load impedance. A complete RF generator is described which meets the desired specifications. This paper is directed to oven designers. Emphasis will be on RF generator characteristics that influence the oven design.
