            Abstract : 
Several methods have been developed for tuning multiple-cavity magnetron oscillators over wide frequency ranges. The most successful of these involves simultaneous variation of both the inductance and capacitance of all the resonant cavities by a single tuning motion. Tuning ranges of better than 1.4 to 1 have been obtained with good efficiency throughout. As an example, a magnetron is described which tunes from 760 to 1160 megacycles, delivering over 2 kilowatts continuous-wave power at any frequency setting.
