Magnetron has the first set of blades 20, which are connected by outputs 52 with a coaxial output device 51 of communication, and the second set of blades 19, which (in one version) alternate with blades of the first set and are not connected with the output communication device. Blades of each set are retained, for instance, by bracing rings, which may be distributed along the length of the anode under one potential relative to each other, and polarity of one set of blades is opposite to polarity of the other set. An additional capacitance link is introduced by means of axial extenders 19a at the ends of the set of blades 19, which are not connected with the output communication device, and by selecting the size the cathode is substantially disconnected from the output communication device due to the opposite polarity of two sets of blades. |

Magnetron with regulated power Present invention relates to electronic devices. The cathode of a magnetron is divided into electrical or thermal sections of arbitrary shape, size or location, connected to voltage proportional to the required power. According to this method, the filament-type cathode of the magnetron is made from a ring with a slit. Filament voltage is applied at the ends of the ring, depending on the power output from the electron-emitting layer deposited on the filament. |

Proposed oscillator has magnetron incorporating main cathode in interaction space and auxiliary thermionic cathode insulated from main one. Inserted between main and auxiliary cathodes is resistor which is connected in parallel with diode. Such connection of diode in parallel with cathode makes it possible to enhance current in direction of injection in interaction space and to set magnetron in working mode. Diode is rated at current injected in magnetron interaction space sufficient for its triggering. |
