Description
Microwave network connection methods, systems and related equipment Technical Field
[0001] This invention relates to the field of wireless communication technology, and in particular to a method, system and related equipment for connecting microwave networks. Background Technology
[0002] With the development of wireless communication technology, the demand for radio frequency (RF) devices in various consumer electronics products is increasing, and the number of integrated electronic components in these products is also growing. Correspondingly, in the design process of RF devices, designers are placing increasingly higher demands on the computational efficiency of simulation software. Taking surface acoustic wave (SAW) filters as an example, a typical SAW filter is composed of multiple discrete components packaged together. Therefore, simulation software needs to connect these discrete components, such as resonators, DMS filters, capacitors, and inductors, and use the electrical performance of the exposed ports as the electrical performance of the device. All of this requires calculating the scattering parameters after the microwave network is connected.
[0003] The current mainstream simulation algorithms include the following two methods:
[0004] Method 1: Calculate the detailed scattering parameters of the two microwave networks, Network A and Network B, using the following formula.
[0005] Method 2 involves calculating the overall scattering parameter matrix of the circuit connections of any microwave network, dividing each port into internal ports and exposed ports, and indexing the exposed ports in the overall scattering parameter matrix to obtain the actual scattering parameter matrix of the circuit.
[0006] The two main methods currently used are primarily aimed at calculating scattering parameters after connecting microwave networks, but each method has its limitations. Method 1 can efficiently calculate series connections between two microwave networks, but in real-world circuits, not only series connections but also parallel connections between multiple devices are very important. Therefore, to address the inability of Method 1 to calculate parallel connections, a power divider is often introduced into multiple parallel microwave networks for calculation.
[0007] Method 2 provides a general circuit calculation approach with the advantage of simulating any circuit without adding a power divider to the circuit connection. However, its disadvantages include the need to introduce port devices to determine the output port during simulation, and the fact that it concatenates the scattering parameters of all microwave networks in the circuit into a large matrix, thus generating a huge amount of computation.
[0008] Although the two mainstream methods mentioned above offer high computational efficiency and general simulation algorithms, they also have limitations in circuit conditions and relatively low simulation efficiency.
[0009] Therefore, there is an urgent need for a new method, system, and related equipment for connecting microwave networks to solve the above-mentioned technical problems. Summary of the Invention

[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0042] Example 1
[0043] Please refer to Figure 1. The present invention provides a method for connecting a microwave network, the method comprising the following steps:
[0044] S1. Obtain the scattering parameters of multiple microwave networks to be connected, and establish a sparse block diagonal matrix based on the scattering parameters.
[0045] In this embodiment of the invention, assuming there are N microwave networks that need to be connected, the corresponding scattering parameters can be named [S] according to the microwave network number. 1 ]…[S N ]. Among them, each scattering parameter [S] i Each of these is a square matrix, with the number of rows and columns representing the number of ports in the microwave network. It should be noted that one or more microwave networks are possible; "multiple" refers to two or more networks as described here.
[0046] Fill all scattering parameters into the sparse block diagonal matrix [S]. This step only creates the sparse block diagonal matrix and does not require calculation. The sparse block diagonal matrix [S] is shown below:
[0047] S2. Analyze the circuit port connection relationships in each microwave network to be connected to obtain an equipotential port list.
[0048] In this embodiment of the invention, the equipotential port list is used to represent the various ports in a microwave network that are directly connected by wires. For example, when two microwave networks N... m With N n When port i and port j are connected (usually referred to as connected in series), the contents of the equivalent potential list are:
[0049] When three microwave networks N m N n With N o When ports i, j, and k are connected (usually referred to as parallel connection), the contents of the equivalent potential list are...
[0050] When a microwave network N m When two internal ports, i and j, are internally connected (usually in a loop), the contents of the equivalent potential list are...
[0051] When a microwave network N m When one port i is not connected to any device (commonly referred to as an open circuit), the contents of the equivalent potential list are as follows:
[0052] S3. Reorder the sparse block diagonal matrix according to the equipotential port list to obtain the first sparse block diagonal matrix.
[0053] In this embodiment of the invention, the sparse block diagonal matrix [S] is reordered, that is, elementary row and column transformations are performed on the sparse block diagonal matrix [S], thereby clustering the equipotential ports in the lower right corner of the sparse block diagonal matrix [S]. For example, the sparse block diagonal matrix [S] is:
[0054] The first and third rows are assumed to be equipotential ports. After moving them to the lower right corner of the matrix through elementary row and column transformations, the following first sparse block diagonal matrix can be obtained:
[0055] S4. Divide the first sparse block diagonal matrix into four sub-matrices according to whether the port attributes are at the same potential, to obtain a second sparse block diagonal matrix including the four sub-matrices.
[0056] In this embodiment of the invention, the sparse block diagonal matrix [S] can be reordered to obtain the first sparse block diagonal matrix [S]′. Based on whether its port attributes are at the same potential, the matrix can be written in the form of a block matrix to obtain the second sparse block diagonal matrix:
[0057] In this configuration, the lower right corner of the second sparse block diagonal matrix is the equal potential port, while the upper left corner of the second sparse block diagonal matrix is the unequal potential port.
[0058] It should be noted that the present invention is not limited to the number of microwave networks (or the dimension of the sparse block diagonal matrix). As long as it is determined whether the port attribute is at the same potential, the first sparse block diagonal matrix is transformed into the second sparse block diagonal matrix as shown above, which includes four sub-matrices.
[0059] S5. Obtain a transfer matrix representing the power distribution of the equipotential port of the microwave network to be connected;
[0060] In this embodiment of the invention, in step S5, the transfer matrix is calculated using the port impedance of the equipotential port of each microwave network to be connected.
[0061] For example, the expression for the transition matrix [T] in the common cases of 1-port common potential, 2-port common potential, and 3-port common potential is as follows:
[0062] S6. The transfer matrix and the second sparse block diagonal matrix are calculated according to a preset rule to obtain a scattering parameter matrix, and the multiple microwave networks to be connected are connected through the scattering parameter matrix.
[0063] In this embodiment of the invention, in step S6, the preset rule is to make the transition matrix and the second sparse block diagonal matrix satisfy the following condition: [S]″=[S′ eu ]([T]-[S′ uu ]) -1 [S′ ue ]+[S′ ee ];
[0064] Where [S]″ represents the scattering parameter matrix, [S′] eu ]、[S′ uu ]、[S′ ue ] and [S′ ee [] represents the submatrix, and [T] represents the transition matrix.
[0065] Specifically, please refer to Figures 2-4. Figure 2 is a schematic diagram of the circuit structure of a T-type filter in the related technology. This T-type filter consists of two inductors, L1 and L2, and a capacitor C. If the connection is made using method one or method two mentioned in the background technology, the result is shown in Figures 3 and 4. Method one requires adding a T-type power divider (T in Figure 3) to the circuit, while method two requires adding port networks (circles in Figure 4) on both sides of the inductors L1 and L2.
[0066] Taking the circuit diagram of a common T-type filter in Figure 1 as an example, this T-type filter consists of two inductors L1 and L2 and a capacitor C. It can be seen that in this invention, a total of three 2-port microwave networks participate in the calculation, therefore the dimension (3*2) of the sparse block diagonal matrix is 6*6, and there are three equipotential ports, hence [S′ ee The dimension of [S′] is 6-3=3, therefore the actual matrix involved in the calculation is [S′]. eu ]([T]-[S′ uu ]) -1 [S′ ue ]+[S′ ee The dimensions are all 3*3.
[0067] In the microwave network connection method shown in Method 1, there are three 2-port networks and one 3-port network involved in the calculation, so the dimension of the S matrix (3*2+3) is 9*9. In the circuit connection method shown in Method 2, there are three 2-port networks and two 1-port networks (the circles in the figure represent 1-port devices), so the dimension of the S matrix (3*2+2*1) is 8*8.
[0068] It can be seen that the microwave network connection method proposed in this invention has significant advantages in terms of computational dimension and higher computational efficiency. This invention can calculate the internal connections, parallel connections, series connections, open circuits, and other circuit conditions of microwave networks. Furthermore, the calculation process does not require the introduction of port devices, nor does it require concatenating the scattering parameters of all microwave networks into a large matrix before calculation, thus ensuring high-efficiency computation.
[0069] Compared with existing technologies, this invention obtains the scattering parameters of multiple microwave networks to be connected and establishes a sparse block diagonal matrix based on the scattering parameters; analyzes the connection relationship of circuit ports in each microwave network to be connected to obtain an equipotential port list; reorders the sparse block diagonal matrix according to the equipotential port list to obtain a first sparse block diagonal matrix; divides the first sparse block diagonal matrix into four sub-matrices according to whether the port attributes are equipotential to obtain a second sparse block diagonal matrix including the four sub-matrices; obtains a transfer matrix to represent the power distribution of the equipotential ports of the microwave networks to be connected; calculates the transfer matrix and the second sparse block diagonal matrix according to preset rules to obtain a scattering parameter matrix, and connects multiple microwave networks to be connected through the scattering parameter matrix. This invention not only removes the limitation that circuit types only support series connections, but also enables simultaneous calculation of commonly used connection methods such as series connection, parallel connection, and open circuit connection, improving the flexibility in handling circuit connections; furthermore, it establishes the scattering parameters as a sparse block diagonal matrix, and divides the sparse block diagonal matrix into four smaller sub-matrices. The computation time complexity of the sub-matrices is lower, which can significantly reduce the computation time and improve the computation efficiency, thereby improving the connection efficiency of microwave networks.

Among them, each scattering parameter [S] i Each of these is a square matrix, with the number of rows and columns equal to the number of ports in the microwave network.
[0074] Fill all scattering parameters into the sparse block diagonal matrix [S]. This step only creates the sparse block diagonal matrix and does not require calculation. The sparse block diagonal matrix [S] is shown below:
[0075] 202. The parsing module is used to parse the circuit port connection relationship in each of the microwave networks to be connected, and obtain an equipotential port list.
[0076] In this embodiment of the invention, the equipotential port list is used to represent the various ports in a microwave network that are directly connected by wires. For example, when two microwave networks N... m With N n When port i and port j are connected (usually referred to as connected in series), the contents of the equivalent potential list are:
[0077] When three microwave networks N m N n With N o When ports i, j, and k are connected (usually referred to as parallel connection), the contents of the equivalent potential list are...
[0078] When a microwave network N m When two internal ports, i and j, are internally connected (usually in a loop), the contents of the equivalent potential list are...
[0079] When a microwave network N m When one port i is not connected to any device (commonly referred to as an open circuit), the contents of the equivalent potential list are as follows:
[0080] 203. Reordering module, used to reorder the sparse block diagonal matrix according to the equipotential port list to obtain the first sparse block diagonal matrix.
[0081] In this embodiment of the invention, the sparse block diagonal matrix [S] is reordered, that is, elementary row and column transformations are performed on the sparse block diagonal matrix [S], thereby clustering the equipotential ports in the lower right corner of the sparse block diagonal matrix [S]. For example, the sparse block diagonal matrix [S] is:

[0084] In this embodiment of the invention, the sparse block diagonal matrix [S] can be reordered to obtain the first sparse block diagonal matrix [S]. ′ Based on whether its port attributes are at the same potential, the matrix can be written in the form of a block matrix, resulting in the second sparse block diagonal matrix:
[0085] In this configuration, the lower right corner of the second sparse block diagonal matrix is the equal potential port, while the upper left corner of the second sparse block diagonal matrix is the unequal potential port.
[0086] It should be noted that the present invention is not limited to the number of microwave networks (or the dimension of the sparse block diagonal matrix).
