Embodiment 1

[0039] The embodiment of the present invention provides a frequency-locked phase-locked structure, such as figure 1 As shown, it includes an intermediate conversion section 2 and several energy couplers, and two adjacent energy couplers are connected through an intermediate conversion section 2;

[0040] The length and impedance of the intermediate transformation section 2 are adjustable.

[0041] In the embodiment of the present invention, through the above-mentioned frequency-locked-phase-locked structure, the high-frequency fields of multiple magnetrons are efficiently coupled to form a whole. Standing waves (or two traveling waves in opposite directions) can be tightly coupled through an appropriate intermediate conversion section 2, so as to achieve high-efficiency frequency-locking and phase-locking.

[0042]In the embodiment of the present invention, the magnetron with multiple output ports includes an energy exporter and at least one energy coupler, and the energy cou...

Embodiment 2

[0052] An embodiment of the present invention provides a magnetron structure composed of the frequency-locked phase-locked structure in Embodiment 1, including n frequency-locked phase-locked structures and no less than n-1 magnetrons;

[0053] Two adjacent magnetrons are connected through the frequency-locked-phase-locked structure.

[0054] The magnetron structure provided by the present invention makes the efficiency of the magnetrons that fight each other higher. On the whole, the magnetrons are not only frequency-locked and phase-locked, but also have higher efficiency than before. That is to say, under the same anode voltage and current conditions, a magnetron with higher efficiency can output more microwave power, and does not lose energy in the mutual coupling process. If a magnetron under a single working condition The power of the power is normalized to 1, then due to the increase in efficiency after phase locking, and the phase locking process does not lose energy, ...

Embodiment 3

[0059] The embodiment of the present invention provides a simulation example of the magnetron structure in Embodiment 2. The magnetron structure works under the pulse wave condition, the operating frequency of the magnetron is 35GHz, and the operating voltage is 10-13kV. The mode is π-mode, the output power of each magnetron is high, close to 10kW, and the efficiency can reach 30%. After frequency-locking and phase-locking through this technology, the operating frequency of the magnetron is locked at 34.9GHz, the phase between the magnetrons is constant and the tuning length is 0° or 180° according to the difference of the intermediate conversion section 2, and the phase of each magnetron The power is close to 10kW, and the efficiency can reach more than 30%.

Abstract

The invention discloses a frequency-locking phase-locking structure and a magnetron structure formed by the frequency-locking phase-locking structure, the frequency-locking phase-locking structure comprises a middle conversion section and a plurality of energy couplers, and two adjacent energy couplers are connected through the middle conversion section; and the length and the impedance of the middle conversion section are adjustable. The invention provides a high-efficiency frequency-locking phase-locking technology which hardly loses the power and efficiency of the original magnetrons, so that microwave output signals of a plurality of magnetrons are coherent, the output signals of the magnetrons can be used for power synthesis, the high-efficiency frequency-locking phase-locking method enables the output signals of large-scale magnetrons to be coherent, and the output signals of the large-scale magnetrons can be used for power synthesis. And the equivalent omnidirectional radiation power of the output coherent signal is increased along with the number N square of the magnetrons.

Description

technical field [0001] The invention belongs to the technical field of microwave sources in vacuum electronic devices, and in particular relates to a frequency-locked-phase-locked structure and a magnetron composed of the same. Background technique [0002] With the development of electronic technology, semiconductor devices have basically replaced electric vacuum devices in low power, low frequency, and low voltage applications, but in high power applications, electric vacuum devices, especially magnetrons, still have an absolute advantage. The magnetron is an electric vacuum device used to generate microwave energy. When the magnetron is working, a DC voltage of several hundred volts to tens of kilovolts is applied between the cathode and the anode. At the same time, the interaction space must be placed between the in a uniform DC magnetic field parallel to the tube axis. Therefore, when the magnetron is working, the DC electric field and the DC magnetic field in the inte...
