<p>A magnetron comprises a cathode (2) and an anode (1) having a plurality of circumferentially spaced resonant cavities (4). An output arrangement includes a generally cylindrical resonant cavity (6) disposed co-axially at one end of the plurality of resonant cavities (4) and within an axial magnetic field. Means are provided for coupling energy directly from each adjacent pair of resonant cavities (4) into the cylindrical cavity (6) and for coupling energy from the cylindrical cavity (6) out of the magnetron. The use of a cylindrical resonant cavity (6) ensures that energy can be coupled symmetrically from each adjacent pair of cavities (4).</p> |
