Japanese Patent JPS5720660
Kind Code:
B2
Abstract:
A coaxial magnetron of the type including a circular electric mode cavity coupled to a vane resonator system is tuned by means of a tuning structure movable in the circular electric mode cavity. The tuning structure includes an array of electrically conductive reactive loading elements, such as vanes, reactively loading the resonator and an adjacent array of field perturbing elements. Relative motion is effected between the two arrays of elements to effect a cyclical variation or modulation of the reactive loading on the cavity and thus the output frequency of the tube.
