[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0024] like Figures 1 to 3 As shown, an ultra-high power bidirectional coupler according to an embodiment of the present invention comprises a cavity 1, a main line connector 2, a main line 3, a branch line connector 4 and a branch line 7. The input port of the cavity 1 is provided with the main line connector 2, the output port of the cavity 1 is provided with the main line connector 2, the main line 3 is provided in the cavity 1, and the inner cores of the two main line connectors 2 are both connected to the main line 3;

[0025] The branch line 7 is provided in the cavity 1 , and the coupling port of the cavity 1 is provided with two branch line connectors 4 , and the inner cores of the two branch line connectors 4 are connected to the branch line 7 .

[0026] In this embodiment, when an input signal is transmitted within cavity 1 through main line connector 2 and main line 3, electromagnetic induction is induced on branch line 7. Due to this electromagnetic induction, an output signal corresponding to the input signal on main line 3 is generated on branch line 7. Conversely, when an output signal is transmitted within cavity 1 through branch line connector 4 and branch line 7, electromagnetic induction is also induced on main line 3, generating a reverse signal corresponding to the output signal on branch line 7. In this way, input signals can be transmitted between main line 3 and branch line 7, achieving bidirectional communication.

[0027] As a result, this ultra-high-power bidirectional coupler achieves broadband operation, operating over a wide frequency range. It can be used in feedback circuits to optimize and adjust system performance. It can control the transmission and coupling of signals in different directions, and in RF circuits, it can synthesize or separate signals of different frequencies. It can be used for power distribution and monitoring, for example, by simultaneously monitoring transmitted and reflected power and sampling signal power for power measurement and monitoring. By monitoring reflected power, it can be used for detection and protection systems, for example, to prevent damage to power amplifiers due to open-circuit reflections. The power loss introduced during signal transmission is relatively small.

[0028] Alternatively, as Figure 2 As shown, the ultra-high power bidirectional coupler further includes an inner cover plate 5 , which is assembled on the cavity 1 and is used to shield the main line 3 .

[0029] In this embodiment, by providing an inner cover plate 5, the interior of the cavity 1 can be sealed, thereby shielding the main line 3 and other structures in the cavity 1, preventing dust and other impurities from entering the cavity 1, which is conducive to maintaining the stable operation of the ultra-high power bidirectional coupler.

[0030] Alternatively, as Figure 2 As shown, the ultra-high power bidirectional coupler further includes an outer cover plate 6 , which is located outside the inner cover plate 5 and assembled on the cavity 1 .

[0031] In this embodiment, an outer cover plate 6 is provided on the outside of the inner cover plate 5 to shield the inner cover plate 5, and the interior of the cavity 1 can be further sealed, thereby shielding the main line 3 and other structures in the cavity 1, preventing dust and other impurities from entering the cavity 1, which is conducive to maintaining the stable operation of the ultra-high power bidirectional coupler.

[0032] Alternatively, as Figure 2 As shown, the main line 3 and the branch line 7 are both configured as guide rods.

[0033] In this embodiment, by arranging both the main line 3 and the branch line 7 as guide rods, it is convenient to connect the main line 3 with the main line connector 2 and to connect the branch line 7 with the branch line connector 4 .

[0034] Alternatively, as Figure 1 and Figure 3 As shown, the two main line connectors 2 are respectively located at the left and right ends of the cavity 1 , and the two branch line connectors 4 are respectively located at the left and right ends of the front side of the cavity 1 .

[0035] In this embodiment, by arranging two main line connectors 2 at the left and right ends of the cavity 1 and arranging two branch line connectors 4 at the left and right ends of the front side of the cavity 1, it is convenient to accurately install the main line connector 2 and the branch line connector 4 at different positions of the cavity 1 without interfering with each other.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
