[0028] Example

[0029] See Figure 1 This embodiment discloses a high-power, high-directivity waveguide coupler, including a main channel 10, a secondary channel 20, a coaxial converter 30, and an isolation window 40. The main channel 10 is an elongated structure with both ends connected. The secondary channel 20 is provided on one side of the main channel 10. The main channel 10 and the secondary channel 20 are integrally formed from the same material.

[0030] Multiple coupling holes 50 are provided between the main channel 10 and the secondary channel 20, and a coaxial converter 30 is provided at each end of the secondary channel 20. Both coaxial converters 30 are located on the side of the secondary channel 20 away from the main channel 10.

[0031] The main channel 10, the secondary channel 20, and the coupling aperture 50 connecting the main channel 10 and the secondary channel 20 enable high-power transmission and high directivity of pulsed radio frequency signals. At the same time, the structure is simple, compact, and reliable.

[0032] An isolation window 40 is provided between each of the two coaxial converters 30 and the two ends of the secondary channel 20. By providing the isolation window 40, a high degree of airtightness can be achieved.

[0033] In this technical solution, the waveguide consists of a main channel 10, a secondary channel 20, and a coaxial converter 30. The waveguide main channel 10 and the waveguide secondary channel 20 are connected through a coupling aperture 50, and then connected to the waveguide coaxial converter 30 through an isolation window 40, thereby achieving high power, high directivity, and high sealing performance.

[0034] Preferably, both the main channel 10 and the sub-channel 20 have rectangular cross-sections, and the coupling aperture 50 is located on the side where the main channel 10 and the sub-channel 20 have narrow sides. This design enables high directivity of pulsed radio frequency signals.

[0035] Preferably, a set of stepped matching blocks 90 are provided at both ends of the secondary channel 20. By setting the stepped matching blocks 90, a 90° bend output can be achieved. The stepped matching blocks 90 are two-stage steps and are located on the side closer to the main channel 10.

[0036] In one specific embodiment:

[0037] A rectangular step 60 is provided at the connection between the coaxial converter 30 and the secondary channel 20. The sealing performance is enhanced by setting the rectangular step 60.

[0038] Preferably, to further enhance the sealing performance, a sealing groove 70 is provided at the connection between the coaxial converter 30 and the secondary channel 20, and a sealing ring 80 is provided in the sealing groove 70.

[0039] In another specific embodiment:

[0040] The secondary channel 20 has a U-shaped cross-section, with both ends forming a 90° angle with the middle. The aforementioned stepped matching block 90 is located at this angle, on the side closer to the main channel 10. Both ends of the secondary channel 20 extend away from the main channel 10, and each end of the secondary channel 20 is connected to a coaxial converter 30.

[0041] This design, along with the matching stepped matching block 90, enables precise 90° elbow output.

[0042] In another specific embodiment:

[0043] The coaxial converter 30 is detachably connected to the sub-channel 20. This detachable connection is typically achieved using screws, allowing the waveguide coupler to switch modes.

[0044] In another specific embodiment:

[0045] All the coupling holes 50 are linearly distributed along the length of the main channel 10 and are evenly distributed in the middle of the main channel 10. High power transmission is achieved by uniformly distributing the coupling holes 50.

[0046] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
