[0020] In the following description, specific details such as specific system architectures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present disclosure. However, those skilled in the art should clearly understand that the present disclosure can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present disclosure.

[0021] To make the objectives, technical solutions, and advantages of the present disclosure clearer, the following will be described through specific embodiments with reference to the accompanying drawings.

[0022] Please refer to Figure 1 , Figure 1 which is a schematic flowchart of a simulation method of a triple-waveguide synthesizer provided by an embodiment of the present disclosure. The method may include S101 to S103.

[0023] S101: Based on the first ladder parameter and the second ladder parameter, use the electromagnetic simulation model to obtain the first power ratio. The first ladder parameter is the power ladder structure parameter of the first branch waveguide, and the second ladder parameter is the ladder structure parameter of the second branch waveguide. The first power ratio is the ratio of the power of the first branch waveguide to the power of the second branch waveguide.

[0024] As Figure 2 and Figure 3 shown, in this embodiment, the structure of a triple-waveguide synthesizer includes:

[0025] A first-level waveguide unit and a second-level waveguide unit. The first-level waveguide unit includes a left-side waveguide unit and a right-side waveguide unit. The left-side waveguide unit includes: a first branch waveguide Z1 and a second branch waveguide Z2. The left-side waveguide unit further includes: a first ladder structure J1, a second ladder structure J2, and a third ladder structure J3. Among them, the ladder structure parameter corresponding to the first ladder structure J1 is the first ladder parameter, the ladder structure parameter corresponding to the second ladder structure J2 is the second ladder parameter, and the ladder structure parameter corresponding to the third ladder structure J3 is the third ladder parameter.

[0026] The right waveguide unit and the left waveguide unit have a symmetric structure.

[0027] The secondary waveguide unit includes a third branch waveguide Z3, a fourth branch waveguide Z4, and a main waveguide Z0. The secondary waveguide unit also includes: a fourth stepped structure J4 and a fifth stepped structure J5. Among them, the stepped structure parameters corresponding to the fourth stepped structure J4 are the fourth stepped parameters, and the stepped structure parameters corresponding to the fifth stepped structure J5 are the fifth stepped parameters.

[0028] The method described in this embodiment is for the left waveguide unit, and corresponding operations can be carried out on the right waveguide unit in the same way.

[0029] In this embodiment, the microwave signal input from the main waveguide Z0 is equally divided by 1:1 by the secondary waveguide unit to obtain two branch microwave signals. Among them, the left branch microwave signal is further equally divided into two microwave signals with a power ratio of 2:1 by the primary waveguide unit, that is, the power ratio of the microwave signal output from the first branch waveguide Z1 to the microwave signal output from the second branch waveguide Z2 is 2:1. The same is true for the right branch microwave signal. Among them, the second branch waveguides Z2 corresponding to the left and right sides share an output end, so finally three microwave signals with a ratio of 1:1:1 will be formed.

[0030] In this embodiment, the first power ratio refers to the ratio of the output powers of the first branch waveguide Z1 and the second branch waveguide Z2, which is determined by the waveguide structure parameters and can be calculated through an electromagnetic simulation model. The first stepped parameter refers to the structure parameters that affect the power distribution of the first branch waveguide Z1, which can include the width of the branch waveguide, the size of the coupling hole, the slope of the tapered transition section, etc. These parameters directly determine the characteristic impedance of the waveguide and thus affect the power distribution ratio. The second stepped parameter refers to the structure parameters that affect the power distribution of the second branch waveguide Z2, which is similar to the first stepped parameter.

[0031] Exemplarily, a three-dimensional model of the triple-waveguide synthesizer is established using professional electromagnetic simulation software such as a high-frequency structure simulation tool, and the structures of the main waveguide Z0, the primary waveguide unit, and the secondary waveguide unit are accurately drawn, and the material parameters are defined, such as the metal conductor, the dielectric constant of the dielectric substrate, the thickness, etc.

[0032] Draw the secondary waveguide unit: For example, if the width of the main waveguide Z0 is designed to be 10 mm, the widths of the symmetric branch waveguides are designed to be equally divided at a ratio of 1:1, such as 5 mm, to ensure equal power division.

[0033] Draw the primary waveguide unit: For example, the width of the left first branch waveguide Z1 is designed to be 6 mm, the width of the second branch waveguide Z2 is designed to be 4 mm (initially meeting the 2:1 power ratio), and the third stepped structure J3 is designed to have an adjustable length.

[0034] The width of the first branch waveguide Z1 and the width of the second branch waveguide Z2 are set as scanning variables, and the parameter scan is performed. The first power ratio under each set of parameters is calculated through the output port power value.

[0035] The parameters of the waveguide unit on the right are completely symmetrical with those on the left, ensuring phase synchronization and power balance of the left and right signals. Simulate the synthesis of three signals to check whether the power at the common output end is equal. If not, fine-tune the matching section of the secondary waveguide.

[0036] Taking processing errors into consideration, verify that the power ratio fluctuation is smaller than the preset fluctuation threshold and the phase difference fluctuation is smaller than the preset phase fluctuation threshold to ensure the design's tolerance to process deviations.

[0037] In summary, through hierarchical parameter adjustment and symmetrical structure design, this method can efficiently realize accurate modeling of the three-in-one waveguide synthesizer, ensuring that the power allocation and phase consistency meet the stringent requirements of high-frequency microwave systems.

[0038] S102: If the difference between the first power ratio and the first target power ratio does not exceed the first power constraint range, determine the first phase value using the electromagnetic simulation model based on the third step parameter. The third step parameter is a phase step structure parameter of the first branch waveguide Z1.

[0039] In this embodiment, the first-level target power ratio refers to the power distribution ratio expected by the design, which is an important indicator for the synthesizer to achieve the predetermined function, such as requiring the two-way output power to reach two to one. The first power constraint range refers to the allowable power ratio deviation range, which is used to screen the parameter combination that preliminarily meets the power distribution requirements, such as allowing the actual power ratio to fluctuate within 5% above and below the target phase value. The first phase value is the phase value of the output signal of the first branch waveguide Z1 obtained by electromagnetic simulation.

[0040] The third-step parameters are structural parameters specifically used to adjust the standing wave as a whole. They correspond to the stepped structures at specific locations in the waveguide (such as the cross-sectional mutation area). Such structures adjust the standing wave ratio by changing the local equivalent impedance and propagation characteristics of the waveguide. The third-step parameters may include step height, step position, number of steps, etc. These parameters directly affect the reflection, transmission phase and mode distribution of electromagnetic waves in the waveguide. The goal of the third-step structure J3 is to reduce the standing wave ratio by optimizing the impedance matching at the waveguide connection to ensure efficient transmission of the signal in the form of traveling waves. The third-step parameters are decoupled from the power allocation parameters (first-step parameters, second-step parameters), and mainly affect the impedance continuity of the waveguide system, thereby adjusting the standing wave ratio without significantly changing the set power allocation ratio.

[0041] The third-step parameters have a significant impact on the first-phase value of the first-branch output. When the third-step parameters are changed, the electromagnetic field distribution and propagation constant in the corresponding waveguide change, resulting in a significant change in the phase delay of the signal when passing through the stepped structure. In the branch waveguide, this phase modulation effect will be directly reflected in the phase value of the branch output. By adjusting the third-step parameters, the phase deviation of each branch can be effectively calibrated to ensure the phase consistency of the multiplexed signals during synthesis, thereby optimizing the power synthesis efficiency and suppressing standing waves.

[0042] With the first-step parameters and the second-step parameters fixed, the third-step parameters are adjusted so that the corresponding phase values meet the constraint conditions to obtain the structural parameters of the synthesizer with better comprehensive index.

[0043] In this embodiment, when the first power ratio is close to the first-level target power ratio, it indicates that the power distribution basically meets the requirements. At this time, the third-step parameters mainly affect the signal phase. By changing the third-step parameters, the electrical length of the signal transmission in the waveguide will be changed, thereby changing the signal phase. The first-phase value under different parameters can be determined using the electromagnetic simulation model.

[0044] Exemplarily, in this embodiment, the electromagnetic simulation model is first used to obtain the first power ratio based on the first-step parameters and the second-step parameters. Then, in this embodiment, it is compared with the first-level target power ratio. If the difference is within the first power constraint range, the next step is entered. The possible value range of the third-step parameters can be determined in advance. For example, the waveguide length can vary within a certain length interval. Within the value range, the values of the third-step parameters are selected one by one and simulated using the electromagnetic simulation model. After each simulation, the phase value of the output signal of the first-branch waveguide Z1 is extracted from the results as the first-phase value. Combining all the simulation results, the first-phase values that meet the phase requirements and their corresponding third-step parameters are screened out.

[0045] S103: If the difference between the first-phase value and the target phase value does not exceed the first-phase constraint range, the third-step parameters, the first-step parameters, and the second-step parameters corresponding to the first-phase value are added to the first-level candidate parameter combination. The target parameter combination is determined from the first-level candidate parameter combination. The target parameter combination is used as the structural parameters of the triple-waveguide synthesizer.

[0046] In this embodiment, the target phase value is the phase value of the microwave output by the third branch waveguide Z3 as designed, which is used to ensure the phase matching of the output signals of the first branch waveguide Z1 and the third branch waveguide Z3. The first phase constraint range refers to the maximum deviation range allowed between the first phase value and the target phase value. The first-level candidate parameter combination is a set composed of three sets of structural parameters that all satisfy the power distribution constraint and the phase constraint, specifically including the first step parameter, the second step parameter, and the third step parameter. The target parameter combination is the optimal parameter group selected from the first-level candidate parameter combinations, and it is necessary to comprehensively consider the performance indicators, processing feasibility, and environmental adaptability of the synthesizer, and finally use it as the structural parameters for actual manufacturing.

[0047] Exemplarily, in the design of a triple-waveguide synthesizer, power distribution and phase consistency are two core indicators. This embodiment realizes collaborative optimization through hierarchical parameter adjustment, specifically including: only when the power ratio and phase value of the first branch waveguide Z1 simultaneously satisfy the design constraints, the corresponding parameter combination is retained, avoiding the situation where a single indicator meets the standard but the overall performance is not excellent. The power-related parameters and the phase-related parameters are decoupled and optimized through electromagnetic simulation. In this embodiment, the first step parameter and the second step parameter are first used to ensure that the power distribution meets the standard, and then the third step parameter is used to calibrate the phase, and finally a candidate parameter library that simultaneously meets the two indicators is formed.

[0048] Exemplarily, this embodiment provides a method of adjusting the power first and then the phase. For example:

[0049] A1: Initialize the first step parameter, the second step parameter, and the third step parameter.

[0050] A2: Determine the first power ratio according to the first step parameter and the second step parameter.

[0051] A3: Calculate the difference between the first power ratio and the first-level target power ratio. If the difference does not exceed the first power constraint range, execute A4.

[0052] A4: Determine the first phase value according to the three-step parameter.

[0053] A5: Calculate the difference between the first phase value and the target phase value. If the difference does not exceed the first phase constraint range, execute A6.

[0054] A6: Use the current first step parameter, second step parameter, and third step parameter as the parameter combination and add it to the first-level candidate parameter combination.

[0055] A7: Adjust the third step parameter and repeat A4 to A7 until the number of parameter combinations in the first-level candidate parameter combination reaches the first target number.

[0056] A8: Adjust the first-stage parameters and the second-stage parameters, and repeat the execution of A2 to A7 until the number of parameter combinations in the first-level candidate parameter combinations reaches the second target number. The first target number is less than the second target number.

[0057] A9: Determine the target parameter combination from the first-level candidate parameter combinations, and construct a triple-waveguide synthesizer according to the target parameter combination.

[0058] In this embodiment, a simulation method for a triple-waveguide synthesizer further includes:

[0059] Based on the third-stage parameters, use the electromagnetic simulation model to determine the first phase value. If the difference between the first phase value and the target phase value does not exceed the first phase constraint range, then based on the first-stage parameters and the second-stage parameters, use the electromagnetic simulation model to obtain the first power ratio.

[0060] If the difference between the first power ratio and the first-level target power ratio does not exceed the first power constraint range, then add the first-stage parameters, the second-stage parameters, and the third-stage parameters corresponding to the first power ratio to the first-level candidate parameter combinations. Determine the target parameter combination from the first-level candidate parameter combinations. Use the target parameter combination as the structural parameters of the triple-waveguide synthesizer.

[0061] This embodiment provides a method of adjusting the phase first and then the power.

[0062] Exemplarily, B1: Initialize the first-stage parameters, the second-stage parameters, and the third-stage parameters.

[0063] B2: Determine the first phase value according to the three-stage parameters.

[0064] B3: Calculate the difference between the first phase value and the target phase value. If the difference does not exceed the first phase constraint range, then execute B4.

[0065] B4: Determine the first power ratio according to the first-stage parameters and the second-stage parameters.

[0066] B5: Calculate the difference between the first power ratio and the first-level target power ratio. If the difference does not exceed the first power constraint range, then execute B6.

[0067] B6: Use the current first-stage parameters, second-stage parameters, and third-stage parameters as a parameter combination, and add them to the first-level candidate parameter combinations.

[0068] B7: Adjust the first-stage parameters and the second-stage parameters, and repeat the execution of B4 to B7 until the number of parameter combinations in the first-level candidate parameter combinations reaches the third target number.

[0069] B8: Adjust the third-stage parameters, and repeat the execution of B3 to B7 until the number of parameter combinations in the first-level candidate parameter combination reaches the fourth target number. The third target number is less than the fourth target number.

[0070] B9: Determine the target parameter combination from the first-level candidate parameter combination, and construct a triple-waveguide synthesizer according to the target parameter combination.

[0071] In this embodiment, a simulation method for a triple-waveguide synthesizer further includes:

[0072] Based on the third-stage parameters, use the electromagnetic simulation model to determine the first phase value. Based on the first-stage parameters and the second-stage parameters, use the electromagnetic simulation model to obtain the first power ratio.

[0073] If the difference between the first phase value and the target phase value does not exceed the first phase constraint range, and the difference between the first power ratio and the first-level target power ratio does not exceed the first power constraint range, then add the first-stage parameters, the second-stage parameters, and the third-stage parameters to the first-level candidate parameter combination. Determine the target parameter combination from the first-level candidate parameter combination. Use the target parameter combination as the structural parameters of the triple-waveguide synthesizer.

[0074] This embodiment provides a method for adjusting power and phase simultaneously.

[0075] Exemplarily, C1: Initialize the first-stage parameters, the second-stage parameters, and the third-stage parameters.

[0076] C2: Determine the first power ratio according to the first-stage parameters and the second-stage parameters, and determine the first phase value according to the third-stage parameters.

[0077] C3: Calculate the phase difference between the first phase value and the target phase value, and calculate the power difference between the first power ratio and the first-level target power ratio. If the power difference does not exceed the first power constraint range and the power difference does not exceed the first phase constraint range, then execute C4.

[0078] C4: Use the current first-stage parameters, second-stage parameters, and third-stage parameters as a parameter combination, and add it to the first-level candidate parameter combination.

[0079] C5: Adjust the first-stage parameters and the second-stage parameters, and repeat the execution of C2 to C5 until the number of parameter combinations in the first-level candidate parameter combination reaches the fifth target number.

[0080] C6: Determine the target parameter combination from the first-level candidate parameter combination, and construct a triple-waveguide synthesizer according to the target parameter combination.

[0081] It can be concluded from the above that in this embodiment, through hierarchical parameter adjustment, the electromagnetic simulation model is used to accurately calculate the influence of the first-step parameters and the second-step parameters on the power ratio between the first branch waveguide Z1 and the second branch waveguide Z2, ensuring that the output power ratio meets the design requirements and satisfies the stringent standards for power distribution in high-frequency microwave systems.

[0082] In this embodiment, the third-step parameters are regarded as the key to phase adjustment. By changing the electromagnetic field distribution and propagation constant in the waveguide, the signal phase delay amount is changed, and the electromagnetic simulation model is used to determine the first phase value under different third-step parameters, ensuring that the phases of multiple signals are consistent during synthesis, optimizing the power synthesis efficiency, and suppressing standing waves.

[0083] This embodiment comprehensively considers two core indicators of power distribution and phase consistency, realizes collaborative optimization through hierarchical parameter adjustment, forms a candidate parameter library that meets both indicators, and screens out the optimal parameter combination from it, taking into account the performance indicators of the synthesizer, processing feasibility, and environmental adaptability. This embodiment also provides various methods such as adjusting power first and then phase, adjusting phase first and then power, and adjusting power and phase simultaneously. Designers can flexibly select according to the actual situation, enhancing design flexibility and improving adaptability to different design requirements.

[0084] In an embodiment of the present disclosure, a simulation method for a three-in-one waveguide synthesizer further includes:

[0085] If the difference between the first power ratio and the first-level target power ratio exceeds the first power constraint range, the first-step parameters and the second-step parameters are adjusted based on the magnitude relationship between the first power ratio and the first-level target power ratio. The first-level target power ratio is 2:1. The first power constraint range is a preset power ratio deviation range.

[0086] Based on the adjusted first-step parameters and the adjusted second-step parameters, the electromagnetic simulation model is used to update the first power ratio until the difference between the updated first power ratio and the first-level target power ratio does not exceed the first power constraint range.

[0087] In this embodiment, a simulation method for a three-in-one waveguide synthesizer further includes:

[0088] If the difference between the first phase value and the target phase value exceeds the first phase constraint range, the third-step parameters are adjusted.

[0089] Based on the adjusted third-step parameters, the electromagnetic simulation model is used to update the first phase value until the difference between the updated first phase value and the target phase value does not exceed the first phase constraint range.

[0090] The first phase constraint range is a preset phase deviation range.

[0091] In this embodiment, when the power distribution or phase consistency does not meet the design requirements, this embodiment enters the iterative adjustment process:

[0092] By changing the structural parameters of the first branch waveguide Z1 and the second branch waveguide Z2, the energy distribution capabilities of the two are adjusted. If the actual power ratio is greater than the target value, it means that the first branch waveguide Z1 obtains too much energy, and it is necessary to reduce the energy acquisition ability of the first branch waveguide Z1 or enhance the energy acquisition ability of the second branch waveguide Z2, and vice versa.

[0093] By adjusting the structural parameters of the first branch waveguide Z1, the time delay of signal transmission can be changed to make its output phase consistent with the output phase of the third branch waveguide Z3, eliminating the phase difference loss during synthesis.

[0094] In this embodiment, by hierarchically adjusting the waveguide structural parameters and combining electromagnetic simulation iteration, the collaborative optimization of power distribution and phase consistency can be efficiently realized. First, by adjusting the parameters of the first two ladders, the energy is ensured to be distributed according to the target ratio, and then the phase difference is accurately calibrated through the parameters of the third ladder. This step-by-step adjustment strategy avoids complex global optimization calculations, improves the design efficiency, and the finally obtained parameter combination can directly guide the device processing, ensuring that the synthesizer has high-precision power balance and phase synchronization performance in practical applications.

[0095] In an embodiment of the present disclosure, a simulation method for a three-in-one waveguide synthesizer further includes:

[0096] Based on the first waveguide width of the main waveguide Z0, the second waveguide width of the third branch waveguide Z3 and the third waveguide width of the fourth branch waveguide Z4 are adjusted. The third branch waveguide Z3 and the fourth branch waveguide Z4 have a symmetric structure, and the second waveguide width is equal to the third waveguide width.

[0097] Based on the adjusted second waveguide width and the adjusted third waveguide width, the second power ratio is obtained by using the electromagnetic simulation model.

[0098] If the difference between the second power ratio and the secondary target power ratio does not exceed the second power constraint range, the adjusted second waveguide width corresponding to the second power ratio is added to the candidate waveguide widths.

[0099] The second power ratio is the ratio of the power corresponding to the third branch waveguide Z3 to the power corresponding to the fourth branch waveguide Z4. The secondary target power ratio is 1:1.

[0100] The input ends of the third branch waveguide Z3 and the fourth branch waveguide Z4 are both connected to the output end of the main waveguide Z0, and the input end of the main waveguide Z0 is used to receive microwave signals.

[0101] The input end of the first branch waveguide Z1 and the input end of the second branch waveguide Z2 are both connected to the output end of the third branch waveguide Z3.

[0102] In this embodiment, a simulation method for a three-in-one waveguide synthesizer further includes:

[0103] Randomly select a target waveguide width from the candidate waveguide widths as the waveguide width of the third branch waveguide Z3, and adjust the fourth ladder parameter of the third branch waveguide Z3.

[0104] Based on the adjusted fourth ladder parameter, obtain a second phase value using an electromagnetic simulation model.

[0105] Select the optimal phase value closest to the target phase value from all the obtained second phase values, and add the adjusted fourth ladder parameter and the target waveguide width corresponding to this optimal phase value to the secondary candidate parameter combination.

[0106] The target phase value refers to the phase value of the microwave input by the main waveguide Z0. The fourth ladder parameter is the ladder structure parameter of the third branch waveguide Z3. The ladder structure parameters of the third branch waveguide Z3 and the fourth branch waveguide Z4 are the same.

[0107] In this embodiment, the main waveguide Z0 refers to the signal input channel of the synthesizer, and the first waveguide width of the main waveguide Z0 determines the basic characteristic impedance of signal transmission. The third branch waveguide Z3 and the fourth branch waveguide Z4 are symmetric branch structures of the secondary waveguide unit, and their physical dimensions are the same to ensure that the input signal is evenly distributed.

[0108] The fourth ladder parameter is the ladder structure parameter of the third branch waveguide Z3. Since the third branch waveguide Z3 and the fourth branch waveguide Z4 are symmetric structures, their ladder structure parameters are exactly the same, and both are used to adjust the phase characteristics of the branch waveguide to ensure that the output signal is in phase with the input signal of the main waveguide Z0. The second power ratio refers to the output power ratio of the third branch waveguide Z3 and the fourth branch waveguide Z4. Ideally, it should be 1:1, and power equalization is achieved by adjusting their waveguide widths. The candidate waveguide widths refer to the set of waveguide widths that meet the requirements of the second power ratio after being screened by power constraints and can be used as the basic parameters for subsequent phase optimization.

[0109] Exemplarily, the secondary waveguide unit, as the pre-stage power distribution module of the synthesizer, realizes equal power distribution of the signal through symmetric structure design, and adjusts the phase of the branch waveguide through the fourth ladder parameter to ensure that the branch output signal is in phase with the input signal of the main waveguide Z0.

[0110] In this embodiment, by adjusting the width ratio of the main waveguide Z0 to the branch waveguides, the output powers of the third and fourth branch waveguides Z4 are ensured to be equal, forming a symmetric power input condition, and providing a stable pre-stage signal for the asymmetric power distribution of the first-stage waveguide unit.

[0111] Based on the equal power distribution, in this embodiment, the electrical length of signal transmission is adjusted through the fourth-order step parameters, aligning the phase of the branch output signal with the phase of the input signal of the main waveguide Z0, and avoiding the decrease in the synthesis efficiency caused by the phase difference.

[0112] Through the symmetric structure design and parameter hierarchical optimization of the second-stage waveguide unit, this embodiment realizes the systematic adjustment from power distribution to phase calibration. This phased optimization strategy effectively solves the power-phase coupling problem in the symmetric structure, improves the quality of the pre-stage signal of the synthesizer, provides a stable input condition for the asymmetric power distribution of the first-stage waveguide unit, and finally ensures that the triple-waveguide synthesizer has high-precision power balance and phase consistency during multi-channel signal synthesis, meeting the engineering requirements of high-frequency microwave systems for high-performance devices.

[0113] In an embodiment of the present disclosure, determining a target parameter combination from the first-stage candidate parameter combinations includes:

[0114] Determining the target parameter combination from the first-stage candidate parameter combinations by using the Newton iteration method.

[0115] In this embodiment, determining the target parameter combination from the first-stage candidate parameter combinations by using the Newton iteration method includes:

[0116] Calculating the standing wave value, power distribution value, and phase loss value corresponding to the first-stage candidate parameter combinations.

[0117] Based on the standing wave value, power distribution value, and phase loss value, determining the target parameter combination from the first-stage candidate parameter combinations by using the Newton iteration method.

[0118] The standing wave value is the power loss value and phase deviation value caused by the standing wave phenomenon. The power distribution value is an index of power distribution.

[0119] In this embodiment, the standing wave value refers to the standing wave phenomenon caused by impedance mismatch in the waveguide system, and the standing wave value can include the power loss value and phase deviation value. The power loss value refers to the energy loss caused by reflection. For example, the larger the voltage standing wave ratio, the larger the return loss and the higher the power loss. The phase deviation value refers to the signal phase distortion caused by the standing wave field distribution. For example, the phase fluctuation intensifies near the standing wave nodes. The power distribution value is an index to measure the power distribution accuracy, that is, the deviation degree between the first power ratio of the first branch waveguide Z1 and the second branch waveguide Z2 and the target power ratio. The phase loss value refers to the synthesis efficiency loss caused by the difference between the first phase value output by the first branch waveguide Z1 and the target phase value. For example, the larger the phase difference, the higher the vector synthesis loss.

[0120] Newton's iteration method is an efficient multi-variable optimization algorithm. By constructing an objective function that includes standing wave value, power value, and phase loss value, and using the parameter gradient information for iterative update, it can quickly converge to the optimal solution.

[0121] In this embodiment, based on the standing wave value, power value, and phase loss value, Newton's iteration method is used to determine the target parameter combination from the first-level candidate parameter combinations, specifically including:

[0122] Substitute the standing wave value, power value, and phase loss value into the objective function, and use Newton's iteration method to determine the target parameter combination from the first-level candidate parameter combinations.

[0123] The objective function is:

[0124]

[0125] Among them, F represents the comprehensive evaluation value of the first-level candidate parameters. is the weight coefficient, and the sum of the weight coefficients is 1. is the actual power ratio, is the phase difference, is the absolute value of the phase difference, and VSWR is the voltage standing wave ratio.

[0126] Exemplarily, in this embodiment, the three indicators of standing wave value, power value, and phase loss value are weighted and combined into an objective function, and the weights are set according to engineering requirements, such as a power splitting weight of 35%, a phase weight of 20%, and a standing wave weight of 40%.

[0127] In this embodiment, a set of parameters is randomly selected from the first-level candidate parameter combinations as the initial solution, and the influence gradient and curvature of each parameter on the objective function are analyzed to determine the direction and step size of parameter adjustment. By continuously correcting the parameter combination, the objective function value is minimized, and finally the optimal solution that simultaneously satisfies power distribution accuracy, phase consistency, and low standing wave is obtained. Calculate the first-order partial derivative of each parameter with respect to the objective function, such as the influence rate of the width of the first branch waveguide Z1 on the power value and the standing wave value, and the influence rate of the length of the first branch waveguide Z1 on the phase loss value and the standing wave value. Calculate the second-order partial derivative (Hessian matrix) between parameters to reflect the parameter coupling relationship.

[0128] Set the convergence threshold, such as the change in the objective function value is less than 0.01, and the maximum number of iterations, such as 50 times. Calculate the initial objective function value, gradient vector, and Hessian matrix. Solve the increment equation to obtain the parameter adjustment amount; update the parameter combination according to the parameter adjustment amount to ensure that the parameters are within the physically feasible range. Perform electromagnetic simulation on the updated parameter combination, calculate the new and updated objective function value; if the difference between the updated objective function value and the previous objective function value is less than the convergence threshold or the maximum number of iterations is reached, terminate the iteration; otherwise, continue to calculate the gradient and Hessian matrix.

[0129] If a certain index improves slowly during the iteration process, its weight can be temporarily increased to guide the optimization direction. Set hard constraints on parameters such as waveguide width and length. If the parameters exceed the boundary during the iteration, they are automatically corrected to the boundary values and the iteration continues.

[0130] Perform machining tolerance simulation on the optimized target parameter combination to verify whether the index fluctuation is within the allowable range. If the objective function values of multiple candidate parameter combinations are close, preferentially select the scheme with symmetric structure and regular parameters to reduce the machining difficulty.

[0131] In this embodiment, the Newton iteration method is used to optimize the first-level candidate parameter combination, which can efficiently handle the multi-parameter coupling problem and find the optimal balance point among power distribution, phase consistency, and standing wave performance. This embodiment uses gradient information to adjust parameters directionally. Compared with random search or single-parameter scanning, the convergence speed is faster, and it can avoid falling into local optimal solutions. Combining the previous hierarchical constraint screening, a complete design process of rough selection - fine tuning - verification is formed. The finally obtained target parameter combination can guide the precision machining of the triple-waveguide synthesizer to ensure its low-loss and high-precision signal synthesis performance in high-frequency microwave systems.
