Description

Technical Field

[0001] The present invention is applicable to the field of wireless communication technology, and in particular relates to a microwave network connection method, system and related equipment. Background Art

[0002] With the development of wireless communication technology, the demand for RF devices in various electronic consumer products is increasing, and the number of electronic components integrated in electronic consumer products is also increasing. Correspondingly, in the design process of RF devices, designers have higher and higher requirements for the calculation efficiency of simulation software. Taking the surface acoustic wave filter as an example, a surface acoustic wave filter is generally composed of multiple discrete device packages. Therefore, in the simulation software, it is necessary to connect multiple discrete devices such as resonators, multi-mode surface acoustic wave filters (DMS), capacitors, inductors, etc., and use the electrical performance of the exposed port of the circuit as the electrical performance of the device, which requires the calculation of 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 two microwave networks Network A and Network B after they are connected using the following formula: :

[0005]

[0006] Method 2 is to calculate the overall scattering parameter matrix of the circuit connection of any microwave network, divide each port into internal ports and exposed ports, and index the exposed ports in the overall scattering parameter matrix to obtain the actual scattering parameter matrix of the circuit.

[0007] The two current mainstream methods are mainly used to solve the problem of calculating scattering parameters after microwave networks are connected, but both methods have certain shortcomings. The method introduced in method 1 can efficiently calculate the circuit series example of two microwave networks, but in actual circuits, there are not only circuit series, but also parallel connection between multiple devices is also a very important connection form. Therefore, in order to solve the problem that method 1 cannot calculate the circuit in parallel, it is often necessary to introduce a power divider in multiple parallel microwave networks for calculation.

[0008] The method introduced in Method 2 provides a general circuit calculation method, which has the advantage that any circuit can be simulated without adding a power divider in the circuit connection. However, its disadvantage is that port devices need to be introduced during the simulation process to determine the output port. Another disadvantage is that the scattering parameters of all microwave networks in the circuit are spliced ​​into a large matrix, which also generates a huge amount of calculation.

[0009] Although the above two mainstream methods provide high computing efficiency and general simulation algorithms respectively, they also have limited circuit conditions and low simulation efficiency.
