Anode voltage is one of the important factors that determine the operating frequency of magnetron. In the magnetron, the value of anode voltage will directly affect the acceleration degree and motion trajectory of electrons in the magnetron, and then affect the oscillation frequency of the microwave. In general, the higher the anode voltage, the more energy the electron gets in the magnetron, and the faster it moves, which leads to an increase in the oscillation frequency of the microwave, that is, the operating frequency of the magnetron increases.



Positive correlation between anode voltage and frequency: In most cases, an increase in anode voltage will lead to an increase in the operating frequency of the magnetron. This is because the increase in anode voltage causes the electrons to gain more energy in the electric field, which increases the oscillation frequency of the electrons. When the anode voltage rises, the energy obtained by the electrons in the electric field increases and the speed of motion increases, resulting in an increase in the cyclotron frequency of the electrons in the magnetic field.

The increase of cyclotron frequency further promotes the formation and stability of microwave oscillation, and makes the operating frequency of magnetron increase correspondingly.

Anode voltage selection range: However, the anode voltage is not the higher the better. Too high an anode voltage may cause the electrons inside the magnetron to move too violently, and may even cause escape or collision effects of electrons, resulting in reduced performance or failure of the magnetron. Therefore, in practical applications, it is necessary to select the appropriate anode voltage range to ensure the stable operation and efficient performance of the magnetron.



In some experimental studies, the specific effect of anode voltage on the operating frequency of magnetron has also been observed. For example, under certain conditions, when the anode voltage gradually increases from a lower value, the operating frequency of the magnetron will increase accordingly. However, when the anode voltage exceeds a certain threshold, the operating frequency of the magnetron may no longer increase significantly, and may even show a downward trend. This may be due to the high anode voltage triggering other physical effects inside the magnetron.

In the design and use of magnetrons, in addition to the anode voltage, but also need to consider the impact of other factors on the operating frequency, such as magnetic field strength, cathode temperature, cavity structure and so on. These factors interact with the anode voltage to determine the operating frequency and performance of the magnetron.



There is a close correlation and interaction between the operating frequency of the magnetron and the anode voltage. In practical applications, it is necessary to select the appropriate anode voltage range and operating parameters according to the specific needs and conditions to achieve stable operation and high efficiency of the magnetron.
