I was asked the other day about a miniature magnetron for a ‘thought-invention’ by a friend. Putting aside (for now) safety and power supply considerations, can they even be miniaturised? Say you wanted a 50- 100W one instead of the usual 1000W.
My intial thoughts, unqualified, are that much of the physical size is related to heat sinking, bulky magents and the resonant cavities, whose size are dictated by the wavelength of microwaves. So no, in other words.
A search online revealed many normal-size magnetrons and an awful lot of unrelated devices called ‘magnetron’ because it sounds cool. Exercise bikes, for example.
