which magnetrons should be replaced together

A magnetron is an electric vacuum device used to generate microwave energy. Its structure includes a cathode, anode, energy output device and magnetic circuit system.

The method and frequency of magnetron replacement depends on factors such as its type, use, operating status and wear. Under normal circumstances, when replacing the magnetron, you do not need to replace both magnetrons at the same time. You only need to replace the damaged or aging one. However, in some special cases, it may be necessary to replace both together, for example:

If the magnetrons work in pairs, such as in a bipolar pulse generator, in order to ensure the synchronization and matching of the two magnetrons, they need to be replaced together.

If the magnetrons are working in series, such as in a high-voltage direct current transmission system, both need to be replaced together to ensure voltage balance and stability.

If the magnetrons are working in parallel, such as in a microwave oven, both need to be replaced together to ensure power distribution and efficiency.

If the magnetron is used in a linear accelerator, such as a particle accelerator in medicine or industry, both of them need to be replaced together to ensure the quality and stability of the particle beam. Because the output power and frequency of the magnetron will attenuate with time, if only one is replaced, the output of the two magnetrons will be inconsistent, affecting the focus and synchronization of the particle beam.

If the magnetron is used in a microwave oven, in order to ensure uniform distribution of microwaves and heating effect, both need to be replaced together. Because the magnetrons of microwave ovens work in parallel, if only one is replaced, the output power and phase of the two magnetrons will not match, causing microwave interference and attenuation.

If the magnetron is used for radar, in order to ensure the detection range and accuracy of the radar, both need to be replaced together. Because the magnetrons of the radar work in pairs, one is used to transmit microwaves and the other is used to receive microwaves. If only one is replaced, the operating frequency and sensitivity of the two magnetrons will be inconsistent, affecting the radar's signal-to-noise ratio and resolution
