Abstract
A magnetron includes a decoupling plate (16) located between the end hat (15) of the magnetron cathode (21) and an output coupling member (11). The use of the decoupling plate (16) presents a high impedance and gives a resonant circuit which is arranged to be resonant at the operating frequency of the magnetron. This prevents or reduces power loss due to capacitive coupling. In another arrangement, the decoupling plate (20) is mounted be a post (21) on the end hat (15) of the magnetron cathode (1).
Claims10
A magnetron comprising:
- a cathode coaxially surrounded by an anode;
- an axial output having an output coupling member connected to the anode;
- and a decoupling plate located between the end of the cathode and said member.
A magnetron as claimed in any preceding claim wherein the plate is of copper.
A magnetron as claimed in any preceding claim and operative at X band.
A magnetron as claimed in any preceding claim wherein anode includes a plurality of anode vanes and the said member includes a disc and electrical connections to connect the disc with alternate anode vanes.
A magnetron substantially as illustrated in and described with reference to FIG. 2,3 or 4 of the accompanying drawings.
