Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of power combiners, and in particular to a 96-in-1 Ku-band waveguide spatial power combiner. Background Art

Obviously, the described embodiments are only part of this solution, not all of it. Based on the embodiments of this solution, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of this solution.
[0045] Throughout the specification, claims, and accompanying figures of this solution, the term "including" and any variations thereof mean "including, but not limited to," and are intended to cover non-exclusive inclusions and are not limited to the examples listed herein. Furthermore, the terms "first" and "second," etc., are used to distinguish between different objects, not to describe a specific order.
[0046] The following describes the implementation of the present disclosure in detail with reference to the accompanying drawings:
[0047] Figure 1 : This is a schematic structural diagram of the input perspective of a 96-in-1 Ku-band waveguide spatial power combiner provided by an embodiment of the present disclosure. Figure 2This is a schematic diagram of the output perspective of a 96-in-1 Ku-band waveguide spatial power combiner provided by an embodiment of the present disclosure. Figure 1 and Figure 2 The 96-in-1 Ku-band waveguide spatial power combiner includes: a one-to-two power splitter module 1, multiple one-to-three power splitters 2, multiple four-in-one power combining modules 3, multiple three-in-one power combiners 4, and a two-in-one power combining module 5;
[0048] The input end of the one-to-two power splitter module 1 is used to receive Ku-band signals, and the output end of the one-to-two power splitter module 1 is electrically connected to the input ends of multiple one-to-three power splitters 2;
[0049] The output ends of the multiple 1-to-3 power splitters 2 are electrically connected to the input ends of the multiple 4-in-1 power combining modules 3, and the output end of the 1-to-3 power splitter 2 is correspondingly connected to the input end of one 4-in-1 power combining module 3;
[0050] The output ends of the multiple four-in-one power synthesis modules 3 are electrically connected to the input ends of the multiple three-in-one power synthesizers 4 respectively; the output ends of the four-in-one power synthesis modules 3 correspond one to one with the input ends of the three-in-one power synthesizers 4;
[0051] The output ends of the multiple three-in-one power combiners 4 are electrically connected to the input ends of the multiple two-in-one power combining modules 5; the output ends of the three-in-one power combiners 4 correspond one to one with the input ends of the two-in-one power combining modules 5;
[0052] The output end of the two-in-one power synthesis module 5 is used to output a synthesis signal.
[0053] In this embodiment, the Ku-band signal refers to an electromagnetic wave signal with a frequency range of 12-18 GHz. The function of the one-to-two power splitter module 1 is to split a Ku-band signal into multiple signals. The one-to-two power splitter module 1 may include multiple one-to-two power splitters. A one-to-two power splitter, also known as a one-to-two power divider, can equally split a single signal into two identical signals. In other words, it evenly distributes the input microwave signal to the two output ports, ensuring that the two output signals have a certain degree of consistency in amplitude and phase.
[0054] For example, in the Ku band, it can distribute the signals in the frequency band to the two branches in a certain proportion, which may be equal proportions in this embodiment, to meet the requirements of subsequent power synthesis.
[0055] In this embodiment, the structure of each 1-to-2 power splitter can be the same or different, depending on its position in the overall structure. Similarly, the function of the 1-to-3 power splitter 2 is to split a Ku-band signal into three signals. In this embodiment, the division can be equal proportions.
[0056] The four-in-one power synthesis module 3 is used to divide the signal received at its input end into four to obtain four first signals, and synthesize the four first signals into one second signal to output to the input end of the three-in-one power synthesizer 4;
[0057] The first signal and the second signal have different powers.
[0058] In this embodiment, the four-in-one power combining module 3 should be understood as a module that integrates several one-to-four power splitters and several four-in-one power combiners, where the number of "several" can also be one. It can be understood that the input of the four-in-one power combining module 3 is a first signal, and the output is also a second signal, the difference being that the power of the second signal is higher than that of the first signal. The input signal is divided into one and combined into four in the four-in-one power combining module 3, thereby achieving a power amplification effect.
[0059] Each three-in-one power combiner 4 can combine three signals into one signal and output it to the two-in-one power combination module 5. Specifically, the three-in-one power combiner 4 is used to first divide one signal into two equal signals, and then divide the two signals according to 2:1 and 1:2 respectively to obtain three equally divided signals. It can be understood that the signal output from the two side ports of the three-in-one power combiner 4 is essentially a signal with a power of 2X, and the signal output from the middle port is essentially a signal with a power of 2X synthesized by two signals with a power of X.
[0060] In this embodiment, in contrast to the aforementioned one-to-two power splitter module 1, the two-in-one power combiner module 5 is used to combine multiple signals into one signal. The two-in-one power combiner module 5 may also contain multiple two-in-one power combiners. In this embodiment, the structure disclosed herein is symmetrically arranged in both the upper and lower parts and in both the left and right parts.
[0061] The structural parameters of the three-in-one power combiner 4 in this embodiment can be obtained through iterative calculation, for example, through the Newton iteration method. During the iteration process, standing wave, power division effect and phase difference can be used as iterative evaluation criteria.
[0062] From the above, it can be concluded that the present disclosure distributes the input Ku-band signal power to multiple branches through a power divider, and then uses multiple power combiners to combine the powers of these branches, so as to realize combining multiple smaller power sources into a larger power output, thereby meeting the system's demand for high-power output.
[0063] Figure 3 This is a schematic diagram of the input perspective of the second 96-in-1 Ku-band waveguide spatial power combiner provided by the embodiment of the present disclosure. Figure 3, in one embodiment of the present disclosure, the one-to-two power splitting module 1 includes a multi-stage one-to-two power splitter;
[0064] The output end of the one-to-two power splitter of the upper stage in the multi-stage one-to-two power splitter is connected to the input end of the one-to-two power splitter of the lower stage;
[0065] The output end of the last-stage one-to-two power splitter in the multi-stage one-to-two power splitter is connected to the input end of the one-to-three power splitter 2 .
[0066] The one-to-two power splitting module 1 includes a plurality of first-level one-to-two power splitters 101, a plurality of second-level one-to-two power splitters 102, and a plurality of third-level one-to-two power splitters 103.
[0067] The input end 10 of the first-stage one-to-two power splitter 101 is the input end of the one-to-two power splitter module 1; the output end of the first-stage one-to-two power splitter 101 is connected to the input end of the second-stage one-to-two power splitter 102;
[0068] The output end of the two-stage one-to-two power splitter 102 is connected to the input end of the three-stage one-to-two power splitter 103;
[0069] The output end of the three-stage one-to-two power splitter 103 is the output end of the one-to-two power splitter module 1 .
[0070] In this embodiment, the power splitters at each level are connected in sequence, and the functions implemented by the power splitters at each level are the same, that is, one input signal is output as two signals. The difference lies in their different structures due to their different spatial distribution.
[0071] In this embodiment, the input terminal 10 of the first-stage one-to-two power splitter 101 is the input terminal of the one-to-two power splitter module 1, that is, the port for receiving Ku-band signals. The first-stage one-to-two power splitter 101 distributes the received Ku-band signal into two signals, which are then input to the second-stage one-to-two power splitter 102. The second-stage one-to-two power splitter 102 further splits the signal into two signals, one of which is input to the third-stage one-to-two power splitter 103. The third-stage one-to-two power splitter 103 further splits the signal into two signals. The output terminal of the third-stage one-to-two power splitter 103 is the output terminal of the one-to-two power splitter module 1.
[0072] The number of the first-stage one-to-two power splitters 101 is a first number; the number of the second-stage one-to-two power splitters 102 is a second number; the number of the third-stage one-to-two power splitters 103 is a third number;
[0073] The first number sequence is a geometric number sequence, which is a number sequence consisting of a first quantity, a second quantity, and a third quantity in sequence.
[0074] The common ratio of the first sequence is 2, and the first quantity is 1;
[0075] The first quantity is smaller than the second quantity; the second quantity is smaller than the third quantity.
[0076] In this embodiment, the number of the first-stage one-to-two power splitters 101 is 1. Since it has two output terminals, the number of the second-stage one-to-two power splitters 102 is 2. Similarly, the number of the third-stage one-to-two power splitters 103 can be 4. Therefore, the common ratio of the first sequence is 2.
[0077] That is, after the power distribution of the one-to-two power splitter module 1, one input signal can be divided into eight signals.
[0078] From the above, it can be concluded that the present disclosure adopts a multi-stage one-to-two power splitter to realize the step-by-step distribution of the signal, reducing the path length of the signal during transmission, thereby reducing signal loss, reducing the superposition and interference of the signal during transmission, and helping to improve the output signal quality.
[0079] Figure 4 This is a schematic diagram of the output perspective of the second 96-in-1 Ku-band waveguide spatial power combiner provided by the embodiment of the present disclosure. Figure 4 In one embodiment of the present disclosure, the two-in-one power combiner module 5 includes: a plurality of first-level two-in-one power combiners 501, a plurality of second-level two-in-one power combiners 502, and a plurality of third-level two-in-one power combiners 503;
[0080] The input end of the first-stage two-in-one power combiner 501 is the input end of the two-in-one power combining module 5; the output end of the first-stage two-in-one power combiner 501 is connected to the input end of the second-stage two-in-one power combiner 502;
[0081] The output end of the two-stage two-in-one power combiner 502 is connected to the input end of the three-stage two-in-one power combiner 503;
[0082] The output end of the three-stage two-in-one power combiner 503 is the output end of the two-in-one power combining module 5 .
[0083] Similar to the one-to-two power splitter module 1 , the two-in-one power combiner module 5 also includes a multi-stage two-in-one power combiner, and the functions of the two-in-one power combiner are not described in detail.
[0084] The output end 50 of the three-stage two-in-one power combiner 503 is the output end of the two-in-one power combining module 5 , and is used to output a combined signal.
[0085] The number of the first-stage two-in-one power combiners 501 is the fourth number; the number of the second-stage two-in-one power combiners 502 is the fifth number; the number of the third-stage two-in-one power combiners 503 is the sixth number;
[0086] The second number sequence is a geometric sequence, which is a sequence consisting of the fourth number, the fifth number, and the sixth number in sequence.
[0087] The common ratio of the second sequence is 0.5, and the fourth number is 4;
[0088] The fourth quantity is greater than the fifth quantity; the fifth quantity is greater than the sixth quantity.
[0089] In this embodiment, contrary to the number of power dividers of each level in the aforementioned one-in-two power splitting module 1, the number of first-level two-in-one power combiners 501 in the two-in-one power combining module 5 is 4, the number of second-level two-in-one power combiners 502 is 2, and the number of third-level two-in-one power combiners 503 is 1.
[0090] The two-in-one power combining module 5 can combine eight channels of signals into one channel.
[0091] From the above, it can be concluded that the two-in-one power synthesis module 5 in the present disclosure adopts a multi-stage two-in-one power synthesizer to realize the step-by-step synthesis of signals, and realizes efficient conversion from multiple inputs to one output. The power synthesizer adopts a multi-stage structure, and the synthesizers at each stage are directly connected, which reduces the path length of the signal during the synthesis process, thereby reducing signal loss.
[0092] Figure 5 This is a schematic diagram of the structure of an isolator provided in an embodiment of the present disclosure, referring to Figure 5 ,In this embodiment, a 96-in-1 Ku-band waveguide spatial power combiner further includes: a plurality of isolators 6;
[0093] The isolator 6 comprises a first port 601 and a second port 602;
[0094] The first port 601 is used to connect the output end of the 1-to-3 power splitter 2 and the input end of the 4-in-1 power combining module 3;
[0095] The second port 602 is used to connect the output end of the four-in-one power combiner module 3 and the input end of the three-in-one power combiner 4 .
[0096] In this embodiment, an isolator 6 is provided between the one-to-three power splitter 2 and the four-in-one power combining module 3, and between the four-in-one power combining module 3 and the three-in-one power combiner 4. The isolator 6 ensures that the signal can only flow from the output end of the one-to-three power splitter 2 through the first port 601 and the second port 602 of the isolator 6 to the three-in-one power combiner 4, preventing the signal from being transmitted in the opposite direction, avoiding interference and power loss caused by reflected signals, and ensuring the stability and efficiency of the power combining process.
[0097] In one embodiment of the present disclosure, the number of one-to-three power splitters 2 is 8, the number of four-in-one power combining modules 3 is 24, the number of three-in-one power combiners 4 is 8, and the number of isolators 6 is 24.

[0099] Figure 7 This is a schematic diagram of the working process of a 96-in-1 Ku-band waveguide spatial power combiner provided by the embodiment of the present disclosure, with reference to Figure 1-4 as well as Figure 7 In this embodiment, the input signal is input to the input end of the one-way power splitter module 1, that is, the input end 10 of a first-level one-way power splitter 101, which divides one signal into two upper and lower signals. After passing through two second-level one-way power splitters 102, the left and right signals are divided into four signals. After passing through four three-level one-way power splitters 103, the front and back signals are divided into eight signals. After passing through eight four-in-one power combining modules 3, the signals are divided into 24 signals. After passing through the one-way four power splitters integrated in the 24 four-in-one power combining modules 3, the signals are divided into 96 signals. Finally, the integrated four-in-one power combiner is used to combine the signals into 24 signals.
[0100] Secondly, it passes through eight three-in-one power combiners 4 in sequence to be combined into eight signals, passes through four first-level two-in-one power combiners 501 to be combined into four signals, passes through two second-level two-in-one power combiners 502 to be combined into two signals, and finally passes through a three-level two-in-one power combiner 503 to be combined into one signal, and the combined signal is output through the output terminal 50 of the three-level two-in-one power combiner 503.
[0101] It can be concluded from the above that the present disclosure ensures unidirectional signal transmission through the isolator 6, making the power synthesis process more stable, reducing the phase fluctuation and amplitude change caused by signal reflection, and improving the reliability of the present disclosure.
