Abstract :
Packaged magnetrons, until a few years ago, had their weight reported in pounds. As the demand for miniaturization increased, however, it became desirable to incorporate ruggedness, tunability, and thermal stability into a magnetron weighing only a few ounces. This paper describes the development and achievement of such a tube: an X-band beacon magnetron, cylindrically shaped, which weighs less than six ounces. Particular attention will be paid to those phases of miniaturization which required revision of traditional design approaches.
